I had a year old version of MSYS2/MinGW that was using PyInstaller with Python3.7 to compile a C GTK application in Windows (python was needed for a plotting script) and everything worked fine until pacman refused to update any packages since I kept getting the error:
error: hook /usr/share/libalpm/hooks/mingw-w64-x84_64-gtk-query-immodules-3.0.hook line 2: invalid value Path
error: hook /usr/share/libalpm/hooks/mingw-w64-x84_64-gtk-update-icon-cache.hook line 2: invalid value Path
Errors occurred, no packages were upgraded.
I looked those up and the general response for it is: "The issue is usually provoked when you don't maintain your system at regular intervals - and I am not thinking yearly - because such neglect will often result in similar problems. The issue stems from a change in pacman code..."
So I decided to start from a fresh MSYS2 install and used the following lines from both an MSYS2 shell and a MinGW-x64 shell, and each of them fails at a different point:
pacman -Syu
pacman -Su
pacman -S nano
pacman -S mingw-w64-i686-gtk3

pip install pyinstaller
In the case of the MSYS2 shell, the pip install pyinstaller fails with:

How to fix: PyInstaller in MSYS2 MinGW 'Your platform is not yet supported'
In the case of a MinGW shell, I can install everything fine, but I cannot compile the C code because I get the error:
fatal error: sys/wait.h: No such file or directory
7 | #include <sys/wait.h>
| ^~~~~~~~~~~~
compilation terminated.
Which means that MinGW doesn't know where to look for this file. It is located in:
msys64/usr/include/sys
but I suppose that only works for an MSYS2 shell? And yet my year old MinGW shell will compile the C code without this error, but despite every effort (following the bash history for package installation for the working version, manually copying over package folders, on and on) I continue to come up against this error. Just copying the folder above into the MinGW include folder results in further issues and is clearly sloppy. I want a repeatable way to get this to work, and I have repeated the process outlined above on several computers and have got the exact same result every time - so I expect anyone starting with a fresh MSYS2 install will run up against the same problems. Any help in getting this to run would be very much appreciated as I am getting frustrated with all of the dead ends.
I was finally able to get this figured out. The first thing to know is that the initial compiling must be done in the MSYS2 shell. Once you successfully compile it in the MSYS2 shell, you can then compile in the MINGW shell without issue. I am not sure why that is so, but I anticipated it would be the case.
I solved the PyInstaller issue by downloading Python 3.7 from http://repo.msys2.org/ and installing it using:
pacman -U python-3.7.2-1-x86_64.pkg.tar
I also needed Python 3.7 installed in Windows, and the path edited in my .bashrc file:
export PYTHON_HOME=C:\\Users\\Leigh\\AppData\\Local\\Programs\\Python\\Python37
export PATH="$PYTHON_HOME:$PYTHON_HOME\\Scripts:$PATH"
I am not sure if PyInstaller is compatible with Python 3.8 yet. I posted an issue to their GitHub page, and it is here for reference in case it is resolved:
https://github.com/pyinstaller/pyinstaller/issues/4996
PyInstaller then worked, but I was met with another issue that I posted to Stack Overflow, but figured out as well. That is here:
MSYS2 gcc fatal error in cc1.exe: cygheap base mismatch detected
After that issue was resolved I could compile my program in MSYS2. Switching over to a MINGW shell, I found that it now compiled there as well.
sys/wait.h isn't there in MinGW, but you can use the one from: https://github.com/win32ports/sys_wait_h
I am trying to build the boost python library on my ubuntu. However, when I execute
./b2 --with-python
It always returns me errors related to
./boost/python/detail/wrap_python.hpp:57:11: fatal error: pyconfig.h: No such file or directory
# include <pyconfig.h>
^~~~~~~~~~~~
I tried to look up online, e.g., https://github.com/boostorg/build/issues/289
Follow their suggestion I check my "project-config.jam"
And I found
# Python configuration
import python ;
if ! [ python.configured ]
{
using python : 3.7 : /home/lowlimb/anaconda3 :/home/lowlimb/anaconda3/include/python3.7m;
}
Which is correct, thus I really don't know how to fix this issue.
Can anyone provide me some advice?
In addition to installing the python dev libs as suggested by the other answers, you can specify the python path directly:
CPLUS_INCLUDE_PATH=/usr/include/python3.7 make
Or in your case something like:
CPLUS_INCLUDE_PATH=/home/lowlimb/anaconda3/include/python3.7 ./b2
This worked for me when compiling a projects using Boost Python where I got the same error.
pyconfig.h is installed with sudo apt install python-dev
To build with a specific python version, you can do
./bootstrap.sh --with-python=<path to python>
e.g.
./bootstrap.sh --with-python=python3
to use your system's python3 or
./bootstrap.sh --with-python=$VIRTUAL_ENV/bin/python
to use the python from your virtual environment.
In order to build Boost-Python or more generally, use Python from C/C++, you need the Python development files:
$ sudo apt install python3.7-dev
I had python 2.7 before and then I installed python 3.4.The OS is windows 10
I have renamed
C:\python27\python.exe to python2.exe (when I run python2 --version it shows correct version)
and
C:\python34\python.exe to python3.exe (when I run python3 --version it shows correct version)
I have set the path variable manually and there is no space etc.
I was trying to create a virtual environment and assign python34 to this new environment.
I was going through this SO reference -- Using VirtualEnv with multiple Python versions on windows
prompt>> virtualenv -p c:\Python34\python3.exe casenv
But I got an error--
Fatal error in launcher: Unable to create process using '"'
Do I need to install virtualenv again for python34 or somewhere I need to set virtualenv path for each python installation.
Any help is highly welcomed.
In my case, i had installed python 3.6 and uninstalled python 2.7 when i got this error.
Completely deleting the C:\Python2.7 directory did the trick.
This error is usually caused because of python directory of different versions stored at same location.
i.e in my case I was using python 3.5.X for development and when I updated to 3.7.6 I got this error.
People on internet suggest that it is because of pip but main cause is 2 or more python directory.
The following steps should fix it:
Uninstall previous python version (or use virtual environment if you want to play with multiple python version)
Delete the python directory you are not using (as it causes confusion for terminal to understand which python path it should pick to execute the command)
and this should fix the error of
fatal error in launcher unable to create process using ' '
Pip version: 10.0.0
Python version: 3.6.5 64 bit
Operating system: Windows 7 Ultimate, Service Pack 1, 64-bit
Description:
After upgrading pip to the version 10.0.0 (from Pycharm, that is using pip as a package) any attempts to start updated pip cause an error:
Fatal error in launcher: Unable to create process using '""c:\program files\python 3.6\python.exe" "C:\Program Files\Python 3.6\Scripts\pip.EXE"'
Command python -m pip works as expected.
I found text "Fatal error in launcher" only in executables:
src\pip_vendor\distlib\t32.exe
src\pip_vendor\distlib\t64.exe
and in the pip.exe itself.
After
python -m pip uninstall pip
easy_install.exe pip
error disappeared.
It is interesting, that initially pip.exe had almost the same size as t64.exe, now it significantly shorter.
If someone came after installing a newer version like 3.X and uninstalled the older version, what you need to do is to delete the old version's folder from C Drive.
Clean Fix (Windows)
The fastest way to fix the issue you were facing is to uninstall and reinstall.
Why it happened?
You probably moved the directory where python was installed.
You probably have both environmental variables listed in Environmental Variables.
Things to consider
You can only use 1 active version of python at a time if you use the MSI installer.
If you downloaded the zip file of Python, you can have unlimited versions in your computer BUT you can only have 1 active version under Environmental Variables.
You can always use any version of Python explicitly by writing the direct path to the specific location of the version of Python.
http://xgboost.readthedocs.org/en/latest/python/python_intro.html
On the homepage of xgboost(above link), it says:
To install XGBoost, do the following steps:
You need to run make in the root directory of the project
In the python-package directory run
python setup.py install
However, when I did it, for step 1 the following error appear:
make : The term 'make' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the
spelling of the name, or if a path was included, verify that the path is correct and try again.
then I skip step1 and did step 2 directly, another error appear:
Traceback (most recent call last):
File "setup.py", line 19, in <module>
LIB_PATH = libpath['find_lib_path']()
File "xgboost/libpath.py", line 44, in find_lib_path
'List of candidates:\n' + ('\n'.join(dll_path)))
__builtin__.XGBoostLibraryNotFound: Cannot find XGBoost Libarary in the candicate path, did you install compilers and run build.sh in root path?
Does anyone know how to install xgboost for python on Windows10 platform? Thanks for your help!
In case anyone's looking for a simpler solution that doesn't require compiling it yourself:
download xgboost whl file from here (make sure to match your python version and system architecture, e.g. "xgboost-0.6-cp35-cp35m-win_amd64.whl" for python 3.5 on 64-bit machine)
open command prompt
cd to your Downloads folder (or wherever you saved the whl file)
pip install xgboost-0.6-cp35-cp35m-win_amd64.whl (or whatever your whl file is named)
If you find it won't install because of a missing dependency, download and install the dependency first and retry.
If it complains about access permissions, try opening your command prompt as Administrator and retry.
This gives you xgboost and the scikit-learn wrapper, and saves you from having to go through the pain of compiling it yourself. :)
Note that as of the most recent release the Microsoft Visual Studio instructions no longer seem to apply as this link returns a 404 error:
https://github.com/dmlc/xgboost/tree/master/windows
You can read more about the removal of the MSVC build from Tianqi Chen's comment here.
So here's what I did to finish a 64-bit build on Windows:
Download and install MinGW-64: http://sourceforge.net/projects/mingw-w64/
On the first screen of the install prompt make sure you set the Architecture to x86_64 and the Threads to win32
I installed to C:\mingw64 (to avoid spaces in the file path) so I added this to my PATH environment variable: C:\mingw64\mingw64\bin
I also noticed that the make utility that is included in bin\mingw64 is called mingw32-make so to simplify things I just renamed this to make
Open a Windows command prompt and type gcc. You should see something like "fatal error: no input file"
Next type make. You should see something like "No targets specified and no makefile found"
Type git. If you don't have git, install it and add it to your
PATH.
These should be all the tools you need to build the xgboost project. To get the source code run these lines:
cd c:\
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
git submodule init
git submodule update
cp make/mingw64.mk config.mk
make -j4
Note that I ran this part from a Cygwin shell. If you are using the Windows command prompt you should be able to change cp to copy and arrive at the same result. However, if the build fails on you for any reason I would recommend trying again using cygwin.
If the build finishes successfully, you should have a file called xgboost.exe located in the project root. To install the Python package, do the following:
cd python-package
python setup.py install
Now you should be good to go. Open up Python, and you can import the package with:
import xgboost as xgb
To test the installation, I went ahead and ran the basic_walkthrough.py file that was included in the demo/guide-python folder of the project and didn't get any errors.
I installed XGBoost successfully in Windows 8 64bit, Python 2.7 with Visual Studio 2013 (don't need mingw64)
Updated 15/02/2017
With newer version of XGBoost, here are my steps
Step 1. Install cmake https://cmake.org/download/
Verify cmake have been installed successfully
$ cmake
Usage
cmake [options] <path-to-source>
cmake [options] <path-to-existing-build>
...
Step 2. Clone xgboost source
$ git clone https://github.com/dmlc/xgboost xgboost_dir
Step 3. Create Visual Studio Project
$ cd xgboost_dir
$ mkdir build
$ cd build
$ cmake .. -G"Visual Studio 12 2013 Win64"
Step 4. Build Visual Studio 2013 project
Open file xgboost_dir/build/ALL_BUILD.vcxproj with Visual Studio 2013
In Visual Studio 2013, open BUILD > Configuration Manager...
choose Release in Active solution configuration
choose x64 in Active solution platform
Click BUILD > Build Solution (Ctrl + Shift +B)
After build solution, two new files libxgboost.dll and xgboost.exe are created in folder xgboost_dir/lib
Step 5. Build python package
Copy file libxgboost.dll to xgboost_dir/python-package
Change directory to xgboost_dir/python-package folder
Run command python setup.py install
Verify xgboost have been installed successfully
$ python -c "import xgboost"
Old Answer
Here are my steps:
git clone https://github.com/dmlc/xgboost
git checkout 9bc3d16
Open project in xgboost/windows with Visual Studio 2013
In Visual Studio 2013, open BUILD > Configuration Manager...,
choose Release in Active solution configuration
choose x64 in Active solution platform
Rebuild xgboost, xgboost_wrapper
Copy all file in xgboost/windows/x64/Release folder to xgboost/wrapper
Go to xgboost/python-package, run command python setup.py install
Check xgboost by running command python -c "import xgboost"
I just installed xgboost both for my python 2.7 and python 3.5, anaconda, 64bit machine and 64 bit python.
both VERY simple, NO VS2013 or git required.
I think it works for normal python, too.
If you use python 3.5:
1: download the package here, the version depends on your python version, python3.5 or python 3.6, 32bit or 64bit.
2: use the command window, use cd to make the download folder as your pwd, then use
pip install filename.whl
OK, finished.
For more detailed steps, see this answer
if you use python 2.7, you do NOT need to download the VS2013 to build it yourself, because I have built it, you can download the file I built and install it directly
1: Download it here by google drive
2: Download it, decompress it, paste it here:
"your python path\Lib\site-packages"
Then you should have something look like this:
3: In python-package folder showed above, use cmd window, cd there and run
python setup.py install
use this code
import xgboost
in your python to check whether you have installed mingw-64 or not, No error information means you have installed the mingw-64 and you are finished.
If there are error information
"WindowsError: [Error 126] "
That means you have not installed mingw-64, and you have one more step to go.
Download the mingw-64 here: http://sourceforge.net/projects/mingw-w64/
Choose x86_64 instead of the default "i686" when you installed the mingw-64,
then add "your install path\x86_64-6.2.0-posix-seh-rt_v5-rev1\mingw64\bin;" to your PATH, it should be something like this:
"C:\Program Files\mingw-w64\x86_64-6.2.0-posix-seh-rt_v5-rev1\mingw64\bin;"
(this is mine).
Don't forget the ";" in the PATH.
Then you are finished,you can use
import xgboost
in your python to check that, Yeah!
PS: if you don't know how to add path, just google it to get solutions. Don't worry, it's very simple.
If You are installing XGBoost for a particular Project and You are using Pycahrm then you need to follow the procedures given below:
Download xgboost‑0.72‑cp36‑cp36m‑win_amd64.whl from Here (as I am using Python 3.6 if you use different version of Python like 2.7 then you need to install xgboost‑0.72‑cp27‑cp27m‑win_amd64.whl).
Copy the to your Project Interpreter directory. You can find the directory of Project Interpreter by clicking File -> Settings -> Project Interpreter from Pycharm.
Open Command Prompt. Go to directory to you Project Interpreter from cmd. Write the following command: pip install xgboost-0.72-cp36-cp36m-win_amd64.whl
On windows 10 , with python 3.6, below command worked.
From Anaconda Prompt, below command can be used directly. The screenshot is attached as proof.
pip install xgboost
After build the c++ version, copy the release dll and lib files in ../windows/x64/Release/..(if you build x64 version) to ../wrapper/ then run python setup.py install
I followed the steps listed in https://www.kaggle.com/c/otto-group-product-classification-challenge/forums/t/13043/run-xgboost-from-windows-and-python. I will summarize what I did below.
1) Download Visual Basic Studio. You can download the community edition at visual studio website. There is a "free visual studio button on the upper right corner"
2) Copy all content from the git hub repository of xgboost/tree/master/windows and Open Visual studio existing project on Visual studio
3) There are a couple of drop down menus you need to select ( "Release" and "X64" and then select build --> build all from the upper menu. It should look something like the attached screenshot.
4) if you see the message ========== Build: 3 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========, it is all good
5) Browse to python-packages folder where the setup file for XGB resides and run the install command 'python setup.py install'.
You can find a similar thread at Install xgboost under python with 32-bit msys failing
Hope this helps.
To add to the solution by Disco4ever for those attempting to build on 32bit Windows machines.
After doing step 6 and creating a config.mk file you need to go into this file and edit the following lines to remove the -m64 flag
export CXX=g++ -m64
export CC=gcc -m64
Adding "git checkout 9a48a40" to Disco4Ever's solution above worked for me:
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
git checkout 9a48a40
git submodule init
git submodule update
This was originally posted by Cortajarena here:
https://github.com/dmlc/xgboost/issues/1267
Also, for what it's worth, I originally had 32 bit Python running on my 64 bit machine and I had to upload 64 bit Python for XGBoost to work.
Thanks to disco4ever answer. I was trying to build xgboost for Python Anaconda environment in my windows 10 64 bit machine. Used Git, mingw64 and basic windows cmd.
Everthing worked for me till the copy step: cp make/mingw64.mk config.mk, as I was using windows cmd I modified it to copy c:\xgboost\make\mingw64.mk c:\xgboost\config.mk
when I proceeded to the next step : make -j4, I got error that build failed. At this stage after so much frustration just tired something different by clicking on build.sh (shell script). It started executing and auto finished.
Then I executed the same step make -j4, to my awe build was successful. I have seen the most awaited xgboost.exe file in my xgboost folder.
I then proceeded with further steps and executed python setup.py install. finally everything installed perfectly. Then I went to my spyder and checked whether it is working or not. But I was one step away to my happiness because I was still seeing the import error.
Closed all command prompts (Anaconda, Git bash, Windows CMD, cygwin terminal) then again opened spyder and typed 'import xgboost'. SUCCESS, No ERROR.
Once again thank you for everyone.
You can install xGBoost using either Visual Studio or minGW. Since, the official xgboost website says that MSVC build is not yet updated, I tried using mingw64.
I am running xgboost (python package) on my win7 x64. Steps I followed were:
1) Follow Disco4Ever's steps for ming64 installation (mentioned above in the answers).
2) Install Git for windows. windows download link. This will also install Git Bash. Add git-installation-directory\cmd to your system environment variable PATH list.
3) Now clone xGBoost in desired location. Type the following in cmd:
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
git submodule init
git submodule update
cp make/mingw64.mk config.mk
make -j4
4) In xgboost's root directory there should be a shell script named "build". Open it. It'll open up a Git Bash and start building. After building, xgboost.exe file will be created.
5) Now install python package :
cd python-package
python setup.py install
You can test by importing xgboost in python.
It took a whole day, but I successfully installed xgboost on windows 7 64-bit box using TDM-GCC with OpenMP enabled, instead of MingW following this link - http://dnc1994.com/2016/03/installing-xgboost-on-windows/
Here's a very helpful link with important points to pay attention to during installation. It's very important to install "openmp". Otherwise you'll get error message.
The link provides a step by step instruction for installing. Here's some quote:
Building Xgboost
To be fair, there is nothing wrong about the official guide for
installing xgboost on Windows. But still, I’d love to stress several
points here to save your time.
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
wget https://www.dropbox.com/s/y8myex4bnuzcp03/Makefile_win?dl=1
cp Makefile_win Makefile
cp make/mingw64.mk config.mk
mingw32-make
Makefile_win is a modified version (thanks to Zhou Xiyou) of the
original Makefile to suit the building process on Windows. You can
wget it or download it here. Be sure to use a UNIX shell for thi
because Windows CMD has issue with mkdir -p command. Git Bash is
recommended. Be sure to use --recursive option with git clone. Be sure
to use a proper MinGW. TDM-GCC is recommended. Note that by default it
wouldn’t install OpenMP for you. You need to specifiy it otherwise the
building would fail.
Another helpful link is the official procedure: official guide
Good luck!
I would like to add a small workaround to Disco4ever 's solution.
For me I was unable to perform cloning in cygwin. So the workaround is perform it in command prompt in windows and do the rest of the task in cygwin.
Use cd c:\xgboost in the 3rd line to make it work in cygwin. So the updated last part is like this.
cd c:\
git clone --recursive https://github.com/dmlc/xgboost
cd c:\xgboost
git submodule init
git submodule update
cp make/mingw64.mk config.mk
make -j4
And after installation is complete you can uninstall git and cygwin but xgboost and mingw64 must be kept as it is.
Note that: before "make -j4" use gcc -v to check your gcc version.
As to me, My environment is win10 + anaconda(python 2.7), when I run make -j4. It shows std::mutex error. After I use gcc- v It echo gcc4.7(anaconda's default gcc).After I choose my gcc to mingw64's 6.2 gcc ,then it works.
Finally, I use "/d/Anaconda2/python.exe setup.py install" install xgboost python packet.
You can install XGBoost using following 3 steps:
Gather information of your system (python version and system architecture - 32 bit or 64 bit)
download related .whl from https://www.lfd.uci.edu/~gohlke/pythonlibs/
e.g. if your python version is 3.7 and windows is 32 bit, then suitable file is:
xgboost‑0.72‑cp37‑cp37m‑win32.whl
run pip install yourdownloadedfile.whl
You can also find detailed steps here.
I use Jupyter notebook and I found a really simple way to install XGBoost within Anaconda:
Install Anaconda
Open Anaconda Navigator
In Environments, update the index and search for xgboost (in not-installed)
Pick libxgboost and py-xgboost and click 'Apply'
Done
I installed pynum and scipy (on osx Lion with python 2.7), but when I tried to build matplotlib
git clone https://github.com/matplotlib/matplotlib.git
cd matplotlib
python setup.py build
python setup.py install
I've got these errors:
/System/Library/Frameworks/ApplicationServices.framework/Frameworks/ATS.framework/Headers/ATSTypes.h:242: error: declaration for parameter ‘FMFontDirectoryFilter’ but no such parameter

Could somebody please tell me what is the problem?
P.S.
At first I tried to install it in this way:
pip install -e git+https://github.com/matplotlib/matplotlib#egg=matplotlib-dev
but it does not worked for me
I always find this process more painful than it should be, but I've done it a few times now and I believe that these steps should get you set up:
Get Xcode 4.3.2, it's required for some of the later steps.
Download the latest version of python for OSX from python.org
Grab the Scipy superpack.
Uninstall any previous versions of numpy/matplotlib/scipy that you currently have. That includes doing cd /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ and moving any numpy/matplotlib/scipy directories or eggs into a temp directory.
cd ~/Downloads(or wherever you downloaded the superpack script to) and run sh install_superpack.sh. Answer no to the question are you installing from a repository cloned to this machine or you'll be confused about why the script keeps failing.
That should be it! You should now be able to boot up the python console and import numpy, scipy, matplotlib.
