PIP 无法安装依赖项

Question

I have built and published a package to pypi using poetry build, and have also specified dependencies which it uses inside pyproject.toml

[tool.poetry.dependencies]
python = "^3.6"
PyGithub = "1.54.1"
colorama = "0.4.4"
PyInquirer = "1.0.3"

However when I install and run this package on a computer without those installed, I get this error

ERROR: Could not find version that satisfies the requirement PyGithub==1.54.1 (from <my_package_name_here) (from versions: none)

ERROR: No matching distribution found for PyGithub==1.54.1 (from <my_package_name_here)

How can I make pip install those automatically whenever someone installs my package using pip install package ? Or is it not possible? This looks like it's trying to install them but can't find them?

Answer 1

So I figured out what was wrong - I was testing the package on test.pypi , and since I was doing that, it was trying to install the required dependencies from there, and not from the ordinary PyPi. When published to PyPi everything is working.

Answer 2

Make sure your are using the public pypi repository index . If not, probably you're using test.pypi or another private repository, which does not contains all dependencies you specified.

In that case you can pass an extra repository index.

Use pip extra-index-url

pip install --index-url https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple PACKAGE==PACKAGE_VERSION

By using an extra index, if pip couldn't find a package in the private repository it'll take look at the oficial index.
