issue on macOS with "linked" python2 #102

Closed pepper-jk closed 4 years ago

pepper-jk commented 4 years ago 
./build.sh: line 34: python3: command not found

Error: Could not create the venv. Please make sure the 'venv' Python-module is installed.

/Users/travis/.travis/functions: line 110: ./run_tests: No such file or directory

The following macOS and xcode combinations are known the make problems regarding python 3.8:

macOS 10.14 with xcode11 macOS 10.13 with xcode10.1

travisCI ref

I'm assuming some problem with homebrew and the python binary, they probably changed it back to just "python".

I'll look into it when I have time to set up a new macOS VM.

I could not reproduce this issue in my macOS VM.

However It seems to be a problem with the brew installation though. I looked a bit more closely at the travisCI log and found this:

The formula built, but is not symlinked into /usr/local

Target /usr/local/Frameworks/Python.framework/Headers
is a symlink belonging to python@2. You can unlink it:
  brew unlink python@2
To force the link and overwrite all conflicting files:
  brew link --overwrite python
To list all files that would be deleted:
  brew link --overwrite --dry-run python

==> Caveats
Python has been installed as

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
  /usr/local/opt/python/libexec/bin
If you need Homebrew's Python 2.7 run
  brew install python@2
You can install Python packages with
  pip3 install <package>
They will install into the site-package directory
  /usr/local/lib/python3.7/site-packages
