Mac 升级pip 9.0.1到10.0.1遇坑记录

首先参考这里https://stackoverflow.com/questions/49768770/not-able-to-install-python-packages-ssl-tlsv1-alert-protocol-version

首先你要pip安装某一个工具的时候遇到下面类似的错误

Traceback (most recent call last):
  File "/Users/finaris/PycharmProjects/test/test/test.py", line 14, in 
    c.request('GET', '/api/config/v1/aaa/users', headers=headers)

也许大多数人直接执行下面的代码就可以解决问题了

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

但是我又遇到了其他问题，类似下面的

ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out.

这时候可以先吧https://bootstrap.pypa.io/get-pip.py这个网页的py文件先下载下来，然后执行

//先到下载的目录
cd /Users/ccMac/Downloads 

//执行
python get-pip.py

假如提示你：

Collecting pip

那么就把这个文件下载下来,自己安装

https://files.pythonhosted.org/packages/0f/74/ecd13431bcc456ed390b44c8a6e917c1820365cbebcb6a8974d1cd045ab4/pip-10.0.1-py2.py3-none-any.whl

下载下来后，然后安装

pip install /Users/ccMac/Downloads/pip-10.0.1-py2.py3-none-any.whl 

假如提示你下面的错误：

....
OSError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/pip'

这样执行：

sudo pip install /Users/liumengkai/Downloads/pip-10.0.1-py2.py3-none-any.whl 

finally:

Successfully installed pip-10.0.1

pip -V
pip 10.0.1 from /Library/Python/2.7/site-packages/pip (python 2.7)
