I wanted to use OpenAL in Python, therefore I tried to install PyAL through the Pycharm project settings.
I got the error message:
No matching distribution found for PyAL
s the requirement PyAL (from version: )
Is this a known issue or am I doing something wrong?
Reference:
Pycharm Community Edition 2016.1.4
pip version 8.1.2
Python 3.5
There is no source or binary distribution for PyAL
Maybe you should download it from bitbucket
The homepage sais:
PyAL is easy to install and integrate within your own projects. Just follow Python's standard procedure of installing packages or look for a prebuilt package for your operating system or distribution.
Unfortunately this is not true. The only way to install PyAL is to download the source and run the setup.py
python setup.py install

I'm having a hard time setting up python packages. EasyInstall from SetupTools is supposed to help that, but they don't have an executable for Python 2.6.
For instance to install Mechanize, I'm just supposed to put the Mechanize folder in C:\Python24\Lib\site-packages according to INSTALL.txt, but runnning the tests does not work. Can someone help shed some light on this? Thanks!
The accepted answer is outdated. So first, pip is preferred over easy_install, (Why use pip over easy_install?). Then follow these steps to install pip on Windows, it's quite easy.
Install setuptools:
curl https://bootstrap.pypa.io/ez_setup.py | python
Install pip:
curl https://bootstrap.pypa.io/get-pip.py | python
Optionally, you can add the path to your environment so that you can use pip anywhere. It's somewhere like C:\Python33\Scripts.
Newer versions of Python for Windows come with the pip package manager. (source)
pip is already installed if you're using Python 2 >=2.7.9 or Python 3 >=3.4
Use that to install packages:
cd C:\Python\Scripts\
pip.exe install <package-name>
So in your case it'd be:
pip.exe install mechanize
This is a good tutorial on how to get easy_install on windows. The short answer: add C:\Python26\Scripts (or whatever python you have installed) to your PATH.
You don't need the executable for setuptools.
You can download the source code, unpack it, traverse to the downloaded directory and run python setup.py install in the command prompt
Starting with Python 2.7, pip is included by default. Simply download your desired package via
python -m pip install [package-name]
As I wrote elsewhere
Packaging in Python is dire. The root cause is that the language ships without a package manager.
Fortunately, there is one package manager for Python, called Pip. Pip is inspired by Ruby's Gem, but lacks some features. Ironically, Pip itself is complicated to install. Installation on the popular 64-bit Windows demands building and installing two packages from source. This is a big ask for anyone new to programming.
So the right thing to do is to install pip. However if you can't be bothered, Christoph Gohlke provides binaries for popular Python packages for all Windows platforms http://www.lfd.uci.edu/~gohlke/pythonlibs/
In fact, building some Python packages requires a C compiler (eg. mingw32) and library headers for the dependencies. This can be a nightmare on Windows, so remember the name Christoph Gohlke.
I had problems in installing packages on Windows. Found the solution. It works in Windows7+. Mainly anything with Windows Powershell should be able to make it work. This can help you get started with it.
Firstly, you'll need to add python installation to your PATH variable. This should help.
You need to download the package in zip format that you are trying to install and unzip it. If it is some odd zip format use 7Zip and it should be extracted.
Navigate to the directory extracted with setup.py using Windows Powershell (Use link for it if you have problems)
Run the command python setup.py install
That worked for me when nothing else was making any sense. I use Python 2.7 but the documentation suggests that same would work for Python 3.x also.
Upgrade the pip via command prompt ( Python Directory )
D:\Python 3.7.2>python -m pip install --upgrade pip
Now you can install the required Module
D:\Python 3.7.2>python -m pip install <<yourModuleName>>
pip is the package installer for python, update it first, then download what you need
python -m pip install --upgrade pip
Then:
python -m pip install <package_name>
You can also just download and run ez_setup.py, though the SetupTools documentation no longer suggests this. Worked fine for me as recently as 2 weeks ago.

Or just put the directory to your pip executable in your system path.
As mentioned by Blauhirn after 2.7 pip is preinstalled. If it is not working for you it might need to be added to path.
However if you run Windows 10 you no longer have to open a terminal to install a module. The same goes for opening Python as well.
You can type directly into the search menu pip install mechanize, select command and it will install:
If anything goes wrong however it may close before you can read the error but still it's a useful shortcut.
For a course I am taking, I need to install the package(?) site into an Anaconda virtual environment. I was able to install the other requirements for the course using the command
pip install 'somename==version'
However, when I ran
pip install 'site==0.0.1'
I got the error message
Could not find a version that satisfies the requirement site (from versions: )
No matching distribution found for site
The only information about site that I can find is (https://libraries.io/pypi/site), but it does not really give much information.
I am using Anaconda 4.4.0 (x86_64) and Python 3.5.3.
Any help would be appreciated. Thanks!
site is internal to the Python interpreter, and is used to initialize machine-specific details of your Python installation.
What's telling you that you need to install this module? Ignore it. It's wrong.
I am using Python 2.7.11 and am trying to pip install modules however a few of them are failing. The message I get is "Failure to build wheel for 'X'" and "Error: INCLUDE Environment Variable is empty".
I tried to install Scrapy, LXML and Twisted and those failed. Some other random modules I tried installed fine.
I have installed pyOpenSSL, added python27 and python27/scripts to environment.
Thanks,
I tried both the solutions offered, none worked.
I installed Microsoft Visual C++ Compiler for Python 2.7, download it here. Then run:
pip install scrapy
That worked for me
A quick solution is to install the pre-compiled version of lxml. You can find it here. If you use the .exe you can point it directly to your python root folder.
After that:
close and re-open cmd
pip install your_package (make sure cmd is in the correct directory)
enjoy having no frustrating lxml errors!
Hope this helped.
Use a pre built library from this link if you are on windows:
https://www.lfd.uci.edu/~gohlke/pythonlibs/
Choose the relevant library given python version and desktop config. For example
I want to install apell in python 3.6 and winamd64 then download this:
aspell_python-1.15-cp36-cp36m-win_amd64.whl
Now go to your console and type
pip install path-to-.whl
and that's it.
I found out that it's impossible to install NumPy/SciPy via installers on Windows 64-bit, that's only possible on 32-bit. Because I need more memory than a 32-bit installation gives me, I need the 64-bit version of everything.
I tried to install everything via Pip and most things worked. But when I came to SciPy, it complained about missing a Fortran compiler. So I installed Fortran via MinGW/MSYS. But you can't install SciPy right away after that, you need to reinstall NumPy. So I tried that, but now it doesn't work anymore via Pip nor via easy_install. Both give these errors:
There are a lot of errors about LNK2019 and LNK1120,.
I get a lot of errors in the range of C: C2065,C2054,C2085,C2143`, etc. They belong together I believe.
There is no Fortran linker found, but I have no idea how to install that, can't find anything on it.
And many more errors which are already out of the visible part of my cmd-windows...
The fatal error is about LNK1120:
build\lib.win-amd64-2.7\numpy\linalg\lapack_lite.pyd : fatal error LNK1120: 7 unresolved externals
error: Setup script exited with error: Command "C:\Users\me\AppData\Local\Programs\Common\Microsoft\Visual C++ for Python\9.0\VC\Bin\amd64\link.exe /DLL /nologo /INCREMENTAL:NO /LIBPATH:C:\BLAS /LIBPATH:C:\Python27\libs /LIBPATH:C:\Python27\PCbuild\amd64 /LIBPATH:build\temp.win-amd64-2.7 lapack.lib blas.lib /EXPORT:initlapack_lite build\temp.win-amd64-2.7\Release\numpy\linalg\lapack_litemodule.obj /OUT:build\lib.win-amd64-2.7\numpy\linalg\lapack_lite.pyd /IMPLIB:build\temp.win-amd64-2.7\Release\numpy\linalg\lapack_lite.lib /MANIFESTFILE:build\temp.win-amd64-2.7\Release\numpy\linalg\lapack_lite.pyd.manifest" failed with exit status 1120
What is the correct way to install the 64-bit versions NumPy and SciPy on a 64-bit Windows machine? Did I miss anything? Do I need to specify something somewhere? There is no information for Windows on these problems that I can find, only for Linux or Mac OS X, but they don't help me as I can't use their commands.
You can install scipy and numpy using their wheels.
First install wheel package if it's already not there...
pip install wheel
Just select the package you want from http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
Example: if you're running python3.5 32 bit on Windows choose scipy-0.18.1-cp35-cp35m-win_amd64.whl then it will automatically download.
Then go to the command line and change the directory to the downloads folder and install the above wheel using pip.
Example:
cd C:\Users\[user]\Downloads
pip install scipy-0.18.1-cp35-cp35m-win_amd64.whl
EDIT: The Numpy project now provides pre-compiled packages in the wheel format (package format enabling compiled code as binary in packages), so the installation is now as easy as with other packages.
Numpy (as also some other packages like Scipy, Pandas etc.) includes lot's of C-, Cython, and Fortran code that needs to be compiled properly, before you can use it. This is, btw, also the reason why these Python-packages provide such fast Linear Algebra.
To get precompiled packages for Windows, have a look at Gohlke's Unofficial Windows Binaries or use a distribution like Winpython (just works) or Anaconda (more complex) which provide an entire preconfigured environment with lots of packages from the scientific python stack.
Installing with pip
You can install the numpy and scipy wheels on Windows with pip in one step if you use the appropriate link from Gohlke's Unofficial Windows Binaries (mentioned by sebix) and run the Windows command prompt as Administrator. For example, in Python 3.5, you would simply use something like this:
# numpy-1.9.3+mkl for Python 3.5 on Win AMD64
pip3.5 install http://www.lfd.uci.edu/~gohlke/pythonlibs/xmshzit7/numpy-1.9.3+mkl-cp35-none-win_amd64.whl
# scipy-0.16.1 for Python 3.5 on Win AMD64
pip3.5 install http://www.lfd.uci.edu/~gohlke/pythonlibs/xmshzit7/scipy-0.16.1-cp35-none-win_amd64.whl
Best solution for this is to download and install VCforPython2.7 from https://www.microsoft.com/en-us/download/details.aspx?id=44266
Then try pip install numpy
Downloading the binaries for 64-bit from http://www.lfd.uci.edu/~gohlke/pythonlibs/, and installing it directly with pip in this order:
pip install numpy-1.12.0+mkl-cp36-cp36m-win64.whl
pip install scipy-0.18.1-cp36-cp36m-win64.whl
pip install matplotlib-2.0.0-cp36-cp36m-win64.whl
Note that you must place command prompt in the folder where you put the .whl files after downloading them, and you must run it as administrator,
worked for me on Windows 10 64-bit now python is up and running.
You can now pip install numpy on Windows!

Intel provides pre-compiled Python modules for free in their "Intel Distribution for Python". The modules are compiled against Intel's MKL (Math Kernel Library) and thus optimized for faster performance. The package includes NumPy, SciPy, scikit-learn, pandas, matplotlib, Numba, tbb, pyDAAL, Jupyter, and others. Find more information and the download link here
If you are on windows , you wouldn't need wheel anyway! You can directly install package by downloading the 32-bit package as win32 from this link [http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy] and then move that downloaded package to cmd's current directory and open cmd and write following codepip install numpy-1.13.1+mkl-cp36-cp36m-win32.whl then do it same for scipy
For 64-bit you need to install mingw-w64 as it is gcc and compiles numpy and scipy as precompiled status.
Currently it works fine with 32-bit.So I had opted for win32 package both for numpy+mkl and scipy in that link.
Hope This works! Give a try
You can download the needed packages from here and use pip install "Abc.whl" from the directory where you have downloaded the file.
Look into python wheels to solve your problem. The best part of python wheels is that they let you install C extensions with no compilers. I just installed numpy and scipy using pip in a clean python install and they both worked fine.
for python 3.6, the following worked for me
launch cmd.exe as administrator
pip install numpy-1.13.0+mkl-cp36-cp36m-win32
pip install scipy-0.19.1-cp36-cp36m-win32
Package version are very important.
I found some stable combination that works on my Windows10 64 bit machine:
pip install numpy-1.12.0+mkl-cp36-cp36m-win64.whl
pip install scipy-0.18.1-cp36-cp36m-win64.whl
pip install matplotlib-2.0.0-cp36-cp36m-win64.whl
Source.
Hey I had the same issue.
You can find all the packages in the link below:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-learn
And choose the package you need for your version of windows and python.
You have to download the file with whl extension. After that, you will copy the file into your python directory then run the following command:
py -3.6 -m pip install matplotlib-2.1.0-cp36-cp36m-win_amd64.whl
Here is an example when I wanted to install matplolib for my python 3.6 https://www.youtube.com/watch?v=MzV4N4XUvYc
and this is the video I followed.
Follow these steps:
Open CMD as administrator
Enter this command : cd..
cd..
cd Program Files\Python38\Scripts
Download the package you want and put it in Python38\Scripts folder.
pip install packagename.whl
Done
You can write your python version instead of "38"

I am trying to install pywin32. I downloaded it from sourceforge.net. When I run
setup.py install
it shows "Unable to find vcvarsall.bat". I Googled about it and found that I have to install MinGW and set path then run
python setup.py build --compiler=mingw32
but it's showing
Can't find a version in Windows.h
Can anybody help? (I have a trial version of Visual Studio 2010 Ultimate installed and MinGW C and C++ compiler installed. Operating system: Windows 7.)
Can anybody tell me a source from where I can download Python binaries already compiled in MinGW, so I don't have to do all this. Or if I can get a python which already have Windows modules.
You can install pywin32 wheel packages from PYPI with PIP by pointing to this package: https://pypi.python.org/pypi/pypiwin32 No need to worry about first downloading the package, just use pip:
pip install pypiwin32
Currently I think this is "the easiest" way to get in working.
are you just trying to install it, or are you looking to build from source?
If you just need to install, the easiest way is to use the MSI installers provided here:
http://sourceforge.net/projects/pywin32/files/pywin32/
(for updated versions)
make sure you get the correct version (matches Python version, 32bit/64bit, etc)
I disagree with the accepted answer being "the easiest", particularly if you want to use virtualenv.
You can use the Unofficial Windows Binaries instead. Download the appropriate wheel from there, and install it with pip:
pip install pywin32-219-cp27-none-win32.whl
(Make sure you pick the one for the right version and bitness of Python).
You might be able to get the URL and install it via pip without downloading it first, but they're made it a bit harder to just grab the URL. Probably better to download it and host it somewhere yourself.
I had the exact same problem. The problem was that Anaconda had not registered Python in the windows registry.
1) pip install pywin
2) execute this script to register Python in the windows registry
3) download the appropriate package form Corey Goldberg's answer and python will be detected
Quoting the README at https://github.com/mhammond/pywin32:
By far the easiest way to use pywin32 is to grab binaries from the most recent release
Just download the installer for your version of Python from https://github.com/mhammond/pywin32/releases and run it, and you're done.
