Error installing mdpo

[keunes]

Hello @mondeja,

Thank you again for the support - I'm creating a separate issue about my installation issue, so the conversation in #169 remains clean for the AntennaPod maintainer when he has a look. I have installed Python 3 using the deadsnakes ppa, and now am on version 3.6.9.

Please see here the output of the installation process:

$ sudo -H python3 -m pip install mdpo

I'm on a (too) old Ubuntu version, so I wouldn't be surprised if this usage is not supported.

[mondeja]

• What exact version of Ubuntu are you using? Just cat /etc/lsb-release.
• For what architecture is built?

[keunes]

• I'm on Ubuntu 18.04.6 LTS
• I'm on a 64-bit system (hard & software)

It seems that your Ubuntu 18.04 build doesn't include wheel by default. Try with pip install wheel or sudo apt-get install -y python-wheel before install mdpo to satisfy a PEP 427 installation.

Thanks @mondeja for looking into this. It seems that, unfortunately, that wasn't the issue:

$ sudo -H python3 -m pip install wheel

[mondeja]

🤔 It seems that maybe wheel needs to be updated, your version is 0.30.0, try sudo -H python3 -m pip install -U wheel.

If doesn't work, try updating pip. sudo -H python3 -m pip install -U pip

If doesn't work, try updating setuptools. sudo -H python3 -m pip install -U setuptools

Here Ubuntu 18.04 successfully installs mdpo for Python3.6 with wheel==0.37.0, setuptools==40.6.2 and pip==21.3.1.

Awesome, updating (wheel and) pip did the trick. Thanks! Now I can start experimenting with mdpo :D
