Windows上升级Python 3.7的pip权限错误解决方法

我正在运行Win10 64位,尝试安装python3.7并升级pip。

我将python安装在d:\python\python372-64(在python文件夹中还有其他版本的python)。

pip应该和python 3一起提供。当我奔跑

pip install pip --upgrade

它说

Found existing installation: pip 18.1

但是

Could not install packages due to an EnvironmentError: [WinError 5] Access is denied: 'd:\\python\\python372-64\\scripts\\pip.exe'. Consider using the '--user' option or check the permissions.'

因此,我尝试以管理员身份运行,但它给了我以下错误:

Traceback (most recent call last):

File "d:\python\python372-64\lib\runpy.py", line 193, in _run_module_as_main

"__main__", mod_spec)

File "d:\python\python372-64\lib\runpy.py", line 85, in _run_code

exec(code, run_globals)

File "D:\Python\Python372-64\Scripts\pip.exe\__main__.py", line 5, in

ModuleNotFoundError: No module named 'pip'

但是,如果我跑步

python -m ensurepip

我明白这一点:

Looking in links: C:\Users\jd\AppData\Local\Temp\tmpcww44m60

Requirement already satisfied: setuptools in d:\python\python372-64\lib\site-packages (40.6.2)

Collecting pip

Installing collected packages: pip

Successfully installed pip-18.1

另外,下面是我的路径环境变量:

D:\Python\Python372-64

D:\Python\Python372-64\Lib\site-packages\

D:\Python\Python372-64\Scripts

我该怎么做才能解决这个问题?
