What does pip install . (dot) mean?


I have a shell script whose last line is:

pip install .

What does it do?

  • pip install <package-name> installs the specified package
  • pip install -r requirements.txt installs all packages specified in requirements.txt

But I am not sure what the above command does.

"Install the project found in the current directory".

This is just a specific case of pip install /path/to-source/tree.

To quote the the pip install documentation describing this usage:

pip install [options] [-e] <local project path> ...

Explicitly, pip install . will execute the setup.py file in the current directory (which will usually load a requirements.txt file).

The dot notation in the pip install dependency is similar to: python3 setup.py develop
