Question

我使用的是windows10和python-3.5。

我想升级我的点子以安装＆＃39; openpyx1＆＃39;模块。

由于以下代码。

c:\Python\Scripts>pip install openpyx1
Collecting openpyx1
  Could not find a version that satisfies the requirement openpyx1 (from 
versions: )
No matching distribution found for openpyx1
You are using pip version 7.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' 
command.

但是这段代码不起作用。

python -m pip install --upgrade pip

这些是我收到的错误消息。

c:\Python\Scripts>python -m pip install --upgrade pip

这些代码也不起作用。

pip install --upgrade setuptools


python -m pip install --upgrade pip --no-cache-dir

我该如何解决这个问题？
