• pin库majoy版本,指定安装版本: mock-django~=0.6.10: It means it will select the latest version of the package, greater or equal to 0.6.10, but still in the 0.6.* version, so it won't download 0.7.0 for example.

pip install --upgrade pip

• 先升级pip``wheel``setuptools然后在尝试一次
• 通过wheel包安装报错,不支持该平台.可以通过python -c "import pip; print(pip.pep425tags.get_supported())"打印看看支持的wheel包类型,修改下载好的wheel包名称Cannot install package from wheel formatpip安装报错：is not a supported wheel on this platform

用pip升级全部的软件包 Upgrading all packages with pip pip freeze --local | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 pip install -U，或者只挑选过期的升级 pip list --outdated --format=freeze | cut -d = -f 1 | xargs -n1 pip install -U
