I record these tips mainly for future references, but I would be glad if you also find this post helpful. And if you have other pip tips, please comment and I will update this post.
1. Install packages with a specific version or version range
A specific version:
pip install foo==1.2.0
A version range:
pip install 'bar>=1.3.2,<=1.5.4'
If the same package with a different version has already been installed, the --force-reinstall should be used.
For multiple packages, it is better to use a requirements.txt file. The syntax is just the same as the single-line version above.
foo==1.2.0
bar>=1.3.2,<=1.5.4
foobar
Then you can run:
pip install -r requirements.txt
2. Use a mirror when downloading packages
One-time use:
pip install -i <mirror-url> foo
Permanent use:
pip config set global.index-url <mirror-url>
3. Use python -m pip instead of plain pip
This will ensure that you are using the correct pip as long as you are using the correct python.

I'd also suggest using
python -mpipinstead. That one less surprise in case thepipyou're using is using a different interpreter than the one you intended to.
