wxPython installation on ubuntu 16.04 taking very long time - python

I am trying to install wxPython on ubuntu 16.04 for python3 using pip3, but after downloading the requirements it stuck in installing it. I have installed the required development packages and their dependencies as mentioned here.

It takes a long time to build, be patient and it will probably make it through if the needed library dependencies are installed. You can use the --verbose flag on pip to see what it is doing along the way.
Alternatively, there are already wheel files available for Ubuntu 16.04, see https://wxpython.org/pages/downloads/

As suggested by RobinDunn use Linux Wheels:
pip install -U \
-f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-16.04 \
wxPython

sudo apt install python3-wxgtk4.0
package in Ubuntu 20.04 which will get you version 4.0.7. Works also 22.04

How can I check if pip can find python dev headers?

I'm trying to install Mujoco on a Ubuntu server and have a problem which very much looks like this: https://github.com/openai/mujoco-py/issues/265
The solution in that issue thread is to install the devel version of python3. Apparently that brings in python.h which is needed by Mujoco.
But things are complicated: I don't have root access on the machine. Pip comes from a conda environment and even on conda-forge, I don't see any dev version of python (Equivalent of apt-get install python3.6-dev for conda)
The installation guide for the server installs some packages with linuxbrew. There is a python package on brew and apparently it automatically ships with the python devel version: how to install python-devel in Mac OS?
Now I have anaconda python and brew python. How can I see which paths are picked up by pip and verify if it sees the python dev headers ?

Install TensorFlow-0.9.0rc0 on Ubuntu 14.04 (64bit) gets not a supported wheel on this platform

While this seems to be a dupe, I cannot resolve, I have a fully current 14.04 Ubuntu and updated PIP yet I am getting, wondering if it is related to being a new release of tensorflow?:
tensorflow-0.9.0rc0-cp27-none-linux_x86_64.whl is not a supported wheel on this platform.
in response to:
sudo pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.9.0rc0-cp27-none-linux_x86_64.whl
Wondering if there is a pip issue? or a wheel issue? I am running a pretty extensive amount if python software all installed fine with pip... So It seems unique to TensorFlow?
Using Python 2 it works for me (on Ubuntu 14.04).
sudo pip2 install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.9.0rc0-cp27-none-linux_x86_64.whl
To use it with Python 3.4, use this:
sudo pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.9.0rc0-cp34-cp34m-linux_x86_64.whl

"Failed building wheel for psycopg2" - MacOSX using virtualenv and pip

I'm attempting to make a website with a few others for the first time, and have run into a weird error when trying to use Django/Python/VirtualEnv. I've found solutions to this problem for other operating systems, such as Ubuntu, but can't find any good solutions for Mac.
This is the relevant code being run:
virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements.txt
After running that block, I get the following errors:
AssertionError
Failed building wheel for django-toolbelt
Running setup.py bdist_wheel for psycopg2
...
AssertionError
Failed building wheel for psycopg2
Failed to build django-toolbelt psycopg2
I believe I've installed the "django-toolbelt" and "psycopg2", so I'm not sure why it would be failing.
The only difference I can think of is that I did not use the command
sudo apt-get install libpq-dev
as was instructed for Ubuntu usage as I believe that installing postgresql with brew took care of the header.
Thanks for any help or insight!
For MacOS users
After trying all the above methods (which did not work for me on MacOS 10.14), that one worked :
Install openssl with brew install openssl if you don't have it already.
add openssl path to LIBRARY_PATH :
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/
install psycopg2 with pip pip3 install psycopg2
I had the same problem on Arch linux. I think that it's not an OS dependant problem. Anyway, I fixed this by finding the outdated packages and updating then.
pip uninstall psycopg2
pip list --outdated
pip install --upgrade wheel
pip install --upgrade setuptools
pip install psycopg2
I was also getting same error.
Using Python 3.7.3 and pip 19.1.1.
I used following command.
pip install psycopg2-binary==2.8.3
TDLR
If you aren't used to installing Python C-extensions, and psycopg2 isn't a core part of your work, try
pip install psycopg2-binary
Building Locally
psycopg2 is a C-extension, so it requires compilation when being installed by pip. The Build Prerequisites section of the docs explain what must be done to make installation via pip possible. In summary (for psycopg 2.8.5):
a C compiler must be installed on the machine
the Python header files must be installed
the libpq header files must be installed
the pg_config program must be installed (it usually comes with the libpq headers) and on $PATH.
With these prerequisites satisfied, pip install psycopg2 ought to succeed.
Installing pre-compiled wheels
Alternatively, pip can install pre-compiled binaries so that compilation (and the associated setup) is not required. They can be installed like this:
pip install psycopg2-binary
The docs note that
The psycopg2-binary package is meant for beginners to start playing with Python and PostgreSQL without the need to meet the build requirements.
but I would suggest that psycopg2-binary is often good enough for local development work if you are not using psycopg2 directly, but just as a dependency.
Concluding advice
Read the informative installation documentation, not only to overcome installation issues but also to understand the impact of using the pre-compiled binaries in some scenarios.
I had same problem and this appears to be a Mojave Issue, I was able to resolve with:
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
For Mac OS X users:
1. First check your postgresql path by running this command in terminal:
pg_config
If this fails lookup how to add pg_config to your path.
2. Next install Xcode Tools by running this command in terminal:
xcode-select --install
If you have both those sorted out now try to install psycopg2 again
For MacOS users, this question has the correct solution:
install command line tools if necessary:
xcode-select --install
then
env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip install psycopg2
I was also facing the same after running all the above commands, but the following two commands worked for me:
Instead of pip, use this:
sudo apt-get install libpq-dev
then run this command:
pip install psycopg2
On OS X, I was able to solve this by simply upgrading wheel before installing psycopg2:
pip install --upgrade wheel
For OSX Sierra users, it seems that an xcode update is the solution: Can't install psycopg2 package through pip install... Is this because of Sierra?
I tried all the above solutions but they did not work for me. What I did was change the psycopg2 version in my requirements.txt file from psycopg2==2.7.4 to psycopg2==2.7.6
Is your error message complete? the most encountered reason for failing to install psycopg2 on mac from pip is pg_config is not in path.
by the way, using macports or fink to install psycopg2 is more recommended way, so you don't have to worry about pg_config, libpq-dev and python-dev.
plus, are using Python 3.5? then upgrage your wheel to > 0.25.0 using pip.
I faced the same issue, but the answers above didn't work for me.
So this is what I did in my requirements.txt
psycopg2-binary==2.7.6.1 and it worked fine
I had this issue on several packages, including psycopg2, numpy, and pandas. I simply removed the version from the requirements.txt file, and it worked.
So instead of psycopg2-binary==2.7.6.1 I just had psycopg2-binary.
I know you are asking for development environment but if you are deploying on server say, Heroku. Just add below line in the requirements.txt of your project.
django-heroku==0.3.1
As this package itself will install the required packages like psycopg2 on server deployment.So let the server(heroku) should take care of it.
sudo apt install libpq-dev python3.X-dev
where X is the sub version,
these should be followed by :
pip install --upgrade wheel
pip install --upgrade setuptools
pip install psycopg2
Enjoy !!!
I solved my problem by updating/installing vs_BuildTools. The link to the software was given in the error itself.
Error Image
Fixed by installing python3.7-dev: sudo apt install python3.7-dev, based on the link.
Python: 3.7
Ubuntu: 20.04.3 LTS

Python - install Pillow and MySQL-python on 1and1 hosting

I've created python virtual environment, installed django using pip and now I would like to install Pillow and MySQL-python using pip but it fails during compile process.
(starting with python.h no such file or directory)
Has anyone tried intall some of these on 1and1 hosting ?
Maybe compile it on different machine or other solution ?
There's not really enough detail here to help. But one possibility is that you don't have the development package for python installed. If you are using Debian or Ubuntu, you can do sudo apt-get install python-dev to install it.

how to install python distutils

I just got some space on a VPS server(running on ubuntu 8.04), and I'm trying to install django on it. The server has python 2.5 installed, but I guess its non standard installation. When I run install script for django, I get
amitoj#ninja:~/Django-1.2.1$ python setup.py install
Traceback (most recent call last):
File "setup.py", line 1, in <module>
from distutils.core import setup
ImportError: No module named distutils.core
I'm stumped. All the articles on internet tell me how to install modules using distutils. But how do I get distutils itself? Can anyone point me to the archive for distutils? I looked in /usr/lib/local/python2.5, /usr/lib/python2.5 etc, and as expected there is no distutils to be found.
I know this is an old question, but I just come across the same issue using Python 3.6 in Ubuntu, and I am able to solve it using the following command (this works in Ubuntu 18.04, 20.04 and 22.04):
sudo apt-get install python3-distutils
If you are unable to install with either of these:
sudo apt-get install python-distutils
sudo apt-get install python3-distutils
Try this instead:
sudo apt-get install python-distutils-extra
Ref: https://groups.google.com/forum/#!topic/beagleboard/RDlTq8sMxro
you can use sudo apt-get install python3-distutils by root permission.
i believe it worked here
You can install the python-distutils package. sudo apt-get install python-distutils should suffice.
I ran across this error on a Beaglebone Black using the standard Angstrom distribution. It is currently running Python 2.7.3, but does not include distutils. The solution for me was to install distutils. (It required su privileges.)
su
opkg install python-distutils
After that installation, the previously erroring command ran fine.
python setup.py build
The simplest way to install setuptools when it isn't already there and you can't use a package manager is to download ez_setup.py and run it with the appropriate Python interpreter. This works even if you have multiple versions of Python around: just run ez_setup.py once with each Python.
Edit: note that recent versions of Python 3 include setuptools in the distribution so you no longer need to install separately. The script mentioned here is only relevant for old versions of Python.
The module not found likely means the packages aren't installed.
Debian has decided that distutils is not a core python package, so it is not included in the last versions of debian and debian-based OSes. You should be able to do
sudo apt-get install python3-distutils
sudo apt-get install python3-apt
If you are in a scenario where you are using one of the latest versions of Ubuntu (or variants like Linux Mint), one which comes with Python 3.8, then you will NOT be able to have Python3.7 distutils, alias not be able to use pip or pipenv with Python 3.7, see:
How to install python-distutils for old python versions
Obviously using Python3.8 is no problem.
This didn't work for me: sudo apt-get install python-distutils
So, I tried this: sudo apt-get install python3-distutils
If the system Python is borked (i.e. the OS packages split distutils in a python-devel package) and you can’t ask a sysadmin to install the missing piece, then you’ll have to install your own Python. It requires some header files and a compiler toolchain. If you can’t have those, try compiling a Python on an identical computer and just copying it.
By searching all python-distutils related package:
apt-cache search x
I get python3-distutils-extra - enhancements to the Python3 build system
Then just try:
sudo apt-get install python3-distutils-extra
