出现以下错误：

MacBook-Pro:$ pip install wheel
Collecting wheel
  Could not fetch URL https://pypi.python.org/simple/wheel/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) - skipping
  Could not find a version that satisfies the requirement wheel (from versions: )
No matching distribution found for wheel
MacBook-Pro:$ pip install --trusted-host pypi.python.org wheel

试试这个没有运气：

pip issue installing almost any library https://github.com/pypa/pip/issues/5236

使用 MacOs Sierra

MacBook-Pro:$ python -V
Python 2.7.10
MacBook-Pro:$ python -m pip --version
pip 9.0.1 from /Library/Python/2.7/site-packages (python 2.7)

有什么帮助吗？

这篇文章有助于解决我的问题： https://medium.com/@dipikabh/ssl-certificate-error-using-pip-install-154aa8e014fb

步骤如下：

升级前检查 pip 版本（稍后验证更新）：

> MacBook-Pro:~ jane$ pip --version

> pip 9.0.1 from /Library/Python/2.7/site-packages (python 2.7)

下载get-pip.py

> curl -O https://bootstrap.pypa.io/get-pip.py

运行以下命令升级 pip：

> MacBook-Pro:~ jane$ sudo python get-pip.py

验证 pip 的版本：

> MacBook-Pro:~ jane$ pip --version
> pip 20.1.1 from /Library/Python/2.7/site-packages (python 2.7)
