Poetry on The Edge Cases

Installing Dependencies from Github Repos with Pip and Poetry

Thu, 16 Nov 2023 20:24:35 +0000

There is a standardized way to install Python packages from VCS repos. The examples will show a complex case that include a branch and subdirectory

pyproject.toml

package-name = {git = "git@github.com:<User>/repo-name.git}
package-name = {git = "git@github.com:<User>/repo-name.git", branch = "test-branch", subdirectory = "repo_dir"}

requirements.txt

package-name @ git+ssh://git@github.com/<User>/repo-name.git
package-name @ git+ssh://git@github.com/<User>/repo-name.git@ptest-branch#subdirectory=repo_dir

pip

This is basically the same format as requirements.txt.

pip install "package-name @ git+ssh://git@github.com/<User>/repo-name.git"
pip install "package-name @ git+ssh://git@github.com/<User>/repo-name.git@ptest-branch#subdirectory=repo_dir"

Private repos

To install from private repos, simply ensure your Github keys are set up on your machine and that they are linked to your Github account (and that you have access to the private accounts).

Using Entry Points in Poetry

If you need to use entry points in a Poetry project, you can use a feature in pyproject.toml for the same behavior as in setuptools. This feature is the heading [tool.poetry.scripts]. Under this, you create the linkage between a command and a function in your script in the form of cmd = "package.module.path:function", giving the fully qualified location of the function using the same dot notation as you would with an import statement.

Using Poetry to Change Python Versions and Create New Virtual Environment

Fri, 25 Mar 2022 00:05:44 +0000

With Poetry, to change an underlying Python version (for testing, etc.) and create a new virtualenv on top of that, use poetry env use /PATH/TO/VERSION/BINARY. For pyenv, this will be poetry env use ~/.pyenv/versions/x.y.z/bin/python3. This will create and activate a new virtual environment, but it won’t show up automatically in the shell. To make it show up, get the full path of the activated virtual environment with poetry env list --full-path, then use that with source /VIRTUALENV/PATH/bin/activate.
