Python error ERROR Could not find a version that satisfies the requirement PyQt4 from versions none

Question

I am trying to install PyQt4 on my python 2.7. But I end up with the following error:

ERROR: Could not find a version that satisfies the requirement PyQt4 (from versions: none)
ERROR: No matching distribution found for PyQt4

Comments

Try installing from the terminal with the following command:

pip install pyqt4

---

I get this when I try installing using pip:

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop
support for Python 2.7.

Which PyQt version are you trying to install?

It's not working even i installed pyqt5 but getting same error.

Are you trying to install it using pip?

Answer 1

You cannot install PyQt directly from pip. Download the file according to your version from here: https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyqt4

And run install the .whl file with pip

Hope it helps!!

For Python version 3.8, you need PyQt5. Try installing PyQt5 instead of PyQt4.

Answer 2

QT does not support Qt4 anymore. But you can install PyQt5 instead:

pip install PyQt5

Answer 3

I downloaded pyqt5 then installed it via pip

Answer 4

You need to install python-qt using pip like this:

pip install python-qt

Answer 5

Every time you need to install pip pkgs, run the following commands beforehand from your cmd (you don't need to be Admin):

set http_proxy=http://your_corp_username:password@<your_corp_proxy_host>:<port>
set https_proxy=https://your_corp_username:password@<your_corp_proxy_host>:<port>

Then run your usual pip commands.

If pip throws some SSL trust/resolution error. You can also do the following to trust pip by your network:

pip --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org install <some_package>

Use the following for installing packages under current user only (this doesn't require Admin privileges)

pip --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org insta
