This means that it will miss an installation if site.py has been removed for some reason and also return directories that aren't Python installations but contain python files named site. check Python installations for a user).ĭir site.py /s technically just checks for all site.py files (which is a module in Python's Standard Library) and returns their parent directory's full path. Since dir /s returns occurrences of within the specified directory and all sub-directories, run this from your C drive (unless you only want to check under a specific directory, e.g. I found this workaround on Webucator and made some small adjustments for powershell.ĭir with the s parameter "lists every occurrence of the specified file name within the specified directory and all subdirectories" ( Microsoft Docs). PowerShell: C:\> dir site.py -s -ErrorAction Silentl圜ontinue 3.7-32 C:\Users\admin\AppData\Local\Programs\Python\Python37-32\python.exe As in this question, try going to the 'Advanced System Settings', edit 'Environment Variables' and include C:python27 (in your case, the place where you installed Python 2.7) to the path. 3.7-64 C:\Users\admin\AppData\Local\Programs\Python\Python37\python.exe * Usually, this kind of problem in Windows occurs because Python isnt in the OS path defined as an environment variable. Using pip to find Python list installed modules and their Versions: To. While "-0p" lists not only the versions, but also the paths: C:\Users\admin>py -0p If you want to know the version of each installed modules, you can use pip program. Installed Pythons found by py Launcher for Windows Which tells me that "-0" (zero, not letter "O") lists the available pythons: C:\Users\admin>py -0 X-64 : Launch the latest 64bit Python X version X.Y-64: Launch the specified 64bit Python version X-32 : Launch the latest 32bit Python X version X.Y-32: Launch the specified 32bit Python version The above all default to 64 bit if a matching 64 bit python is present. X.Y : Launch the specified Python version 3 : Launch the latest Python 3.x version 2 : Launch the latest Python 2.x version By typing "py -h" or "py -help" I got the help message: C:\Users\admin>py -h The requirements.txt I used: gevent=1.0.I just got the answer.

XKCD Summary It’s easy to install multiple versions of python on a Mac computer using installers from, Homebrew, Conda, or other sources. I'm assuming I messed up something that cause docker didn't install the packages properly. It does work if I install all the packages manually. However, my code doesn't work in the container.
