Question

我升级了点子。但是升级后会有一些语法错误。

我尝试安装python 3.x，但未修复。

回溯（最近通话最近一次）：

File "/usr/bin/pip", line 7, in <module>
    from pip._internal import main
  File "/usr/lib/python2.6/site-packages/pip/_internal/__init__.py", line 19, in <module>
    from pip._vendor.urllib3.exceptions import DependencyWarning
  File "/usr/lib/python2.6/site-packages/pip/_vendor/urllib3/__init__.py", line 8, in <module>
    from .connectionpool import (
  File "/usr/lib/python2.6/site-packages/pip/_vendor/urllib3/connectionpool.py", line 92
    _blocking_errnos = {errno.EAGAIN, errno.EWOULDBLOCK}

我尝试安装pyopenssl

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Answer 1

不再支持python2.6，请尝试将您的SYS PATH更改为指向新的python和pip

检查此：Python ENV

或者，您可以使用以下内容：

{{1}}

Answer 2

使用此链接Change default python version

更改默认python版本

您已经为python2环境安装了pyopenssl。所以先将其卸载。

检查版本：python3.6 -V，pip3 -V等在安装pyopenssl或任何软件时，请使用pip3。

使用 sudo pip3 install pyopenssl 或 pip3 install pyopenssl ，它将起作用。
