python pip 安装失败

Question

我正在尝试安装库 pynput 使用 sudo pip install pynput

但我收到此错误日志。任何其他 python 软件包都发生过这种情况。以前一切正常突然出现这些错误我试图从

复制错误日志

~/.pip/pip.log

这就是我所拥有的：

Answer 1

尝试使用

更新 pip

sudo -H pip2 install --upgrade pip

命令。

Answer 2

存在类似的问题here。

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 requests 和 urllib3 模块的最新版本。

Answer 3

我成功了。从

中手动删除 requests、urllib

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

并使用 sudo easy_install requests

重新安装请求

然后 sudo easy_install pip==9.0.1

Answer 4

下面的解决方案对我有用。

卸载 pip2
使用 PyPI 安装 pip2（参考 https://www.howtodojo.com/2016/03/install-use-pip-ubuntu-14-04/ 中的 'Install pip From PyPI' 部分）注意：从 ubuntu 存储库安装在我的情况下不起作用。
然后我在使用 pip2 安装任何模块时不再遇到 ValueConstraintError（例如：pip2 install invoke）

Answer 5

您需要更新 pip。只需输入此命令

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

更新后bash -l

就是这样。
