Issue
I'm trying to install lektor into a new virtualenv using pyenv virtualenv. I have no problem making a new virtualenv with Python 3.7.0, but when I try to pip install lektor, I get a build failure with watchdog and the following error message:
pyenv: clang: command not found
The `clang' command exists in these Python versions:
anaconda3-5.0.0
error: command 'clang' failed with exit status 127
I understand that the anaconda3 version has clang, but I also have a version installed in /usr/bin. The output of which -a clang is:
$PYENV_ROOT/shims/clang
/usr/bin/clang
Can I manually set the shim to point to usr/bin? Or is there a different solution to this issue?
Solution
This is a rotten solution, but it does work. By taking the shim for clang and temporarily moving it (e.g., mv $PYENV_ROOT/shims/clang ~/Desktop), watchdog can be installed, then the clang shim can be moved back to the original location. A better option would be for pyenv to default to the system versions of programs if a shim doesn't point anywhere in a given environment…
Alternative solution
The pyenv plugin pyenv-which-ext takes care of this class of issues by checking for the existence of utilities in the normal $PATH after seeing that they aren't present in the current environment. It's a quick install via Homebrew, took care of all my issues.
