安装时如何告诉 pip 保持最新版本的库？

Question

my requirements.txt :

google-api-python-client>=1.6.2
httplib2==0.9.2
...

In this case google-api-python-client installs the httplib2=0.14.0 . But I would be overwritten to the older version on the next line.

Of course, in this case, I could act. But there are some cases that a lib depends on another, that depends on another, etc. So I'm wondering whether there's a way to tell pip to always keep the most recent version of the libs.

like: pip install -r --keep-most-recent requirements.txt

Answer 1

This would mean that pip should install the latest version of the requirements and their dependencies no matter what the version constraints in requirements.txt are, is that right? Impossible as far as I know.

Not sure exactly what you are trying to achieve but maybe you would prefer working with one of these tools:

• poetry update
• pip-compile --upgrade
• pipenv update
