我无法在Windows 10命令提示符下安装sklearn，numpy和scipy以在Python 3.6上使用

Question

I have Python 3.6 correctly installed and have been working on Eclipse. But I cannot use the libraries. Every time I import them I get an error message:

Traceback (most recent call last):
  File "C:\Users\gilbe\eclipse-workspace\python3.6\BeginnerFiles\IrisDataSet", line 1, in <module>
    from sklearn import datasets
ModuleNotFoundError: No module named 'sklearn'`

When I tried installing sklearn, numpy, and scipy, I type in the following into Windows Command Prompt:

"pip install numpy", "pip install scipy", or "pip install sklearn".

However, I get an error message every time. For example:

C:\Program Files (x86)\Python36-32\Scripts>pip install sklearn

You are using pip version 9.0.3, however version 10.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

Further, when I try to upgrade the pip command using the suggested command above, I also get an error message:

My real question here is how do I fix these issues, and install these libraries correctly, I have spent a whole day trying to fix this in different ways, including: installing the libraries from inside Eclipse, through Window>Preferences>Interpreter>Python Interpreter>Install with pip , Uninstalling and Reinstalling Python, attempting to use the easy_install <package> command.

Please help.

Answer 1

right click on the windows button on bottom left of your screen. Then go to "Windows PowerShell(Admin). There you try your pip installs. It will definitely work. I think you don't have the admin access that is why you are seeing.

PermissionError: [WinError 5] Access is denied

Just open the cmd with admin as user.Hope this helps.
