Pomoc ze środowiskiem Pythona.

[Łukasz Maśko]

Od razu zaznaczę, że nie znam się na Pythonie ni w ząb. A napotkałem na jakiś 
problem z naszą instalacją, która nie pozwala mi skompilować paczki softu dla 
Greaseweazle. Efekt jest taki (wiem, że długie ale wklejam całość bo nic z 
tego nie rozumiem):

$ python3 -m pip install .
Defaulting to user installation because normal site-packages is not writeable

ModuleNotFoundError: No module named 'setuptools'


Tyle tylko, że:
$ rpm -qa | grep -E "python3-(setuptools|wheel)"
python3-setuptools-62.0.0-2.noarch
python3-wheel-0.37.1-3.noarch
python3-setuptools_git-1.2-6.noarch
python3-setuptools_scm-6.0.1-1.noarch

Czy da się z tego loga wywnioskować, czego brakuje? Jedyna sugestia autora 
softu jest taka: "This looks pretty broken. No setuptools but you have 
setuptools... maybe investigate pyenv and install yourself a pristine python3 
environment and try within that." - niezbyt pomocna.
