Using Python 3.8.0 on Mac OS 10.15.3 (Catalina) with pyenv.

When I try to run a file, it returns:

ModuleNotFoundError: No module named '_tkinter'

I've tried brew install tcl-tk. I'm a little worried that because I'm running python on top of pyenv, any third party tkinter module doesn't get run properly.

Running brew doctor returned:

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew-provided
script of the same name. We found the following "config" scripts:
  `/Users/jm/.pyenv/shims/python3.7-config
  /Users/jm/.pyenv/shims/python3.7m-config
  /Users/jm/.pyenv/shims/python-config
  /Users/jm/.pyenv/shims/python3-config
  /Users/jm/.pyenv/shims/python3.8-config`

  • What do `brew doctor` and `brew upgrade python3` commands show? – Redowan Delowar Feb 10 '20 at 04:36

  • Try removing the `python3.7` configs. See this [issue](https://discourse.brew.sh/t/python3-installation-with-tkinter/3636). – Redowan Delowar Feb 10 '20 at 04:55
  • will it affect my pyenv setup though? – doctopus Feb 10 '20 at 05:10

    When using Python there are a number of library management systems such as pip. My advice would be to only use one of them. I would also recommend Anaconda Navigator, which does all this stuff automatically. – nerak99 Apr 28 '21 at 13:05

You should install tkinter. To install tkinter write this on console:

pip install tk
