Question

我试图通过Windows 7上的“ cmd”中的pip通过PyPI安装一些软件包，如下所示：

C:\Users\acer\PycharmProjects\Test\venv\Scripts>pip install (some package)

但是安装失败并显示以下消息（直接从cmd收到）：

Exception:

During handling of the above exception, another exception occurred:

You are using pip version 10.0.1, however version 18.0 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

我尝试将pip升级到版本18.0，因此我在cmd（Windows 7）上运行python -m pip install --upgrade：

C:\Users\acer\PycharmProjects\Test\venv\Scripts>python -m pip install --upgrade pip

运行它之后，我输入pip --version来检查我现在的版本：

C:\Users\acer\PycharmProjects\Test\venv\Scripts>pip --version

但是响应是我有pip版本10.0.1：

pip 10.0.1 from c:\users\acer\pycharmprojects\test\venv\lib\site-packages\pip-10.0.1-py3.7.egg\pip (python 3.7)

再次运行升级命令后，响应pip已经是最新的：

Requirement already up-to-date: pip in c:\users\acer\pycharmprojects\test\venv\lib\site-packages (18.0)

两个答案为什么有区别？以及如何正确升级点子？

pip升级：“ python -m pip install --upgrade”说已经是最新的（18.0），“ pip --version”说（10.0.1）
