Answer 1

这里存在类似的问题。

问题似乎是PyPI证书现在有超过64个SAN名称，打破了旧版本请求中的硬编码最大值。

确保您拥有请求和urllib3模块的最新版本。

Answer 2

我得到了它的工作。 从中删除requests ， urllib

/usr/local/lib/python2.7/dist-packages

并使用sudo easy_install requests重新安装sudo easy_install requests

然后sudo easy_install pip==9.0.1

Answer 3

尝试使用更新点子

sudo -H pip2 install --upgrade pip

命令。

Answer 4

下面的解决方案为我工作 。

1. 卸载pip2
2. 使用PyPI安装pip2（请参阅https://www.howtodojo.com/2016/03/install-use-pip-ubuntu-14-04/中的 '从PyPI安装pip'部分）注意：从ubuntu存储库安装没有在我的情况下工作。
3. 然后我在使用pip2安装任何模块时不再获得ValueConstraintError（例如：pip2 install invoke）

Answer 5

你需要更新点子。 只需输入此命令即可

curl  https://bootstrap.pypa.io/get-pip.py | sudo python

更新后bash -l

而已。
