使用 pip3

在pipUbuntu 14.04 上，我收到此错误：

Traceback (most recent call last):

AttributeError: 'module' object has no attribute 'SSL_ST_INIT'

我该如何解决这个问题？

答案1

使用 pip3

我不得不改用以下方法来pip3解决这个问题：

$ sudo pip3 install --upgrade pyopenssl

答案2

我找到stackoverflow 上的这个答案有帮助。基本上，它说你应该这样做：

rm -rf /home/<Your Username>/.local/lib/python2.7/site-packages/OpenSSL
sudo rm -rf usr/local/lib/python2.7/dist-packages/OpenSSL/
pip install pyOpenSSL

答案3

是的，pip 会出现错误，直到您手动修复它（提到鸡和蛋）...找到库的安装位置并手动删除它。

在我的 16.04 安装中我这样做了：

cd /usr/lib/python2.7/dist-packages
rm -rf OpenSSL

然后 pip 就可以正常工作，不再出现 SSL 错误

pip 安装 pyopenssl

答案4

您缺少 pyOpenSSL 包，或者其已过时。

只需运行

$ pip install pyopenssl

并更新包（可能没有必要）。
