Why Does My pip Installation Fail from TestPyPI, and How Can I Fix Missing Requirements?

Pip Installation Fails from TestPypi Due to Missing Requirements

When attempting to install a python package from testpypi, you may encounter an error stating that certain requirements cannot be found. This is because testpypi does not have access to the same repositories as the regular PyPI server.

To resolve this issue, you need to specify the location of the required packages when installing from testpypi. Here's how you can do it:

pip install --extra-index-url https://testpypi.python.org/pypi poirot

In this command:

• --extra-index-url specifies the URL of the testpypi server.
• https://testpypi.python.org/pypi is the default URL for testpypi.
• poirot is the name of the package you are trying to install.

This command will instruct pip to search for the required packages (tqdm and Jinja2) on testpypi first and then on the regular PyPI server if the packages are not found on testpypi.

Note:

Using --extra-index-url can be unsafe in certain situations, such as when mixing public and private PyPI servers. It's recommended to use this option with caution and assess your own risks.
