python2 中 pip

指定安装 python2 的 pip
wget https://bootstrap.pypa.io/pip/2.7/get-pip.py && python get-pip.py
pip==20.3.4 是 pip 中 支持 python2 的最高版本。
在之后的版本 (如 pip>=21.0) 就舍弃了python2 (使用会 error, ). 只支持 python3.
Note: pip 21.0, in January 2021, removed Python 2 support, per pip’s Python 2 support policy. Please migrate to Python 3.

Python 2 Support

pip 20.3 was the last version of pip that supported Python 2. Bugs reported with pip which only occur on Python 2.7 will likely be closed as “won’t fix” issues by pip’s maintainers

ubuntu 中 pip

Ubuntu comes with a version of PIP from precambrian and that’s how you have to upgrade it if you do not want to spend hours and hours debugging pip related issues.

apt-get remove python-pip python3-pip
wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py
python3 get-pip.py

As you observed I included information for both Python 2.x and 3.x
