找不到满足需求轮python的版本。

Question

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--运气不好：

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

使用MacOs塞拉利昂

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)

在这方面有什么帮助吗？

1. 运行以下命令来升级pip:
