Question

尝试在我的终端升级pip。这是我的代码：

(env) macbook-pro83:zappatest zorgan$ pip install --upgrade pip
Could not fetch URL https://pypi.python.org/simple/pip/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:645) - skipping
Requirement already up-to-date: pip in ./env/lib/python3.5/site-packages
You are using pip version 8.1.2, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

知道问题是什么吗？执行There was a problem confirming the ssl certificate时，我也会收到相同的错误pip install django。

修改 pip install --upgrade pip -vvv returns：

Answer 1

通过以下命令管理修复它（卸载并重新安装pip）：

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

Answer 2

一个。检查您的系统日期和时间，看看它是否正确。

湾如果第一个解决方案没有修复它，请尝试使用较低安全性的方法：

pip install --index-url=http://pypi.python.org/simple/linkchecker

这会绕过HTTPS并使用HTTP，只有在您赶时间时才尝试此解决方法。

℃。尝试将pip降级为不使用SSL验证的版本：

pip install pip==1.2.1

然后通过以下方式再次将pip升级回新版本：

pip install --upgrade pip

d。如果上述情况无效，请卸载pip并重新安装。
