I am trying to install the following packages in a pipenv virtualenv buy it has been impossible in a Mac M1. I haven't tried in another PC

I have used bot possible packages

Option 1

[packages]
pyqt5-sip = "*"
pyqt5 = "*"

Option 2

[packages]
pyqt5-sip = "==12.7.0"
pyqt5 = "==5.10.1". #This package doesn't seem to exist

I will post the different errors from te different installation methods

Backstory

Here are the steps that have surely been helpful in getting pipenv to work with pyqt5 on an Apple Mac M1 machine.

A big part of this was that I've overlooked using pip instead of the pipenv command to accept the terms of licenses. This was huge wasted time since pipenv would become stuck for up to an hour before showing the failure, and to make matters worst, you won't see the error due to the license terms when you run pipenv install without the --verbose flag.

Steps

  1. Make sure you have successfully installed pyqt5 from homebrew:

    brew install pyqt@5

  2. Open your ~/.zshrc in a text editor and add the following line:

    export PATH="/opt/homebrew/opt/qt5/bin:$PATH"

    you might need to adapt the path based on your homebrew install folder. If you're not sure, you can run brew --prefix qt5 to find the exact path

  3. Open a new terminal or type in the existing terminal:

    source ~/.zshrc

  4. Go to your Python project folder and type:

    pipenv shell
pip install pyqt5 --config-settings --confirm-license= --verbose

  5. Grab a coffee and wait for step 4 to complete, this will take some time, but if you ran with the '--verbose' command you should see quickly (within less than a minute) the logs:

     Querying qmake about your Qt installation...
 This is the GPL version of PyQt 5.15.9 (licensed under the GNU General  Public License) for Python 3.11.3 on darwin.
 Found the license file 'pyqt-gpl.sip'.
 Checking to see if the QtCore bindings can be built...

    This is good news, it means at least your installation didn't get stuck because of the license as you would if you were to run pipenv ...

    And if you're lucky, after roughly 10-15 minutes, you'll see:

    Successfully installed pyqt5-5.15.9

In summary:

The trick was to use pip install and NOT pipenv install within the virtual environment (run pipenv shell first)
