Problems while installing (PyGTK)

nihal111 commented 6 years ago

I ran into problems while installing screenkey. sudo ./setup.py install gave errors for both pycairo and PyGTK.

pycairo

pycairo did not install straight from the install script.

Solution

I had to manually install pycairo, only worked after I did- sudo apt-get install libcairo2-dev libjpeg-dev libgif-dev and then pip install pycairo to run. It threw a Package cairo was not found in the pkg-config search path. Comment on pycairo issue SO Ref

PyGTK

Installing pygtk was a real headache, even messed up my pip and setuptools. I tried installing using sudo pip install pygtk, only to get this error

Reference which explains the same problem

Solution

I found this gist that installs PyGTK. (simple ./configure && make; stuff I believe). Running the install script still didn't allow me to proceed since PyGTK wasn't installed as a pip package. I had to modify the setup.py file and remove 'PyGTK' from the install_requires list.

After doing all this, I was finally able to get it to work. Hope this helps someone.

This is not unsurprising. Language package managers such as pip will fail flatly on their face for anything but the simplest pure-python dependency.

I had to manually install pycairo, only worked after I did- sudo apt-get install libcairo2-dev libjpeg-dev libgif-dev and then pip install pycairo to run.

The README instructions for ubuntu/debian involve installing pygtk and pycairo via:

apt-get install python-gtk2

This should work correctly and install python-cairo as a dependency. This will also result in way less installed dependencies, as there's no need to have developer tools installed.

Is there a reason why this didn't work before attempting to install pygtk from source?

apt-get install python-gtk2

Oh, yes I had done that. Also had tried apt-get install python-gtk2-dev Neither stopped me from getting this error. I'm unsure why.

Thanks @nihal111 this helped me out; here was my process:

sudo apt-get install python-gtk2

remove PyGTK from install_requires, line 33 of setup.py. Post edit looks as such:

      scripts=['screenkey'],
      packages=['Screenkey'],
      setup_requires=['setuptools', 'python-distutils-extra'],
      install_requires=['pycairo'],
      data_files=[('share/applications', ['data/screenkey.desktop']),
                  ('share/doc/screenkey', ['README.rst', 'NEWS.rst'])],
