PyQt5 pip installation error 13. Permission denied

问题

I'm trying to install PyQt5 with the command pip install PyQt5

but I get an error instead.

I use Python 3.5, windows 10.

error:

C:\WINDOWS\system32>pip install PyQt5

回答1:

With different Windows (8.2) and different PyQt (4-4) I had the same problem.

What worked for me was: run task manager and see if there are any Python tasks running. If there are (there were for me) kill them, as they (probably) lock the sip.pyd file. Then run pip install again ("successfully installed" in my case).

回答2:

Python3.6 Win10 x64 with Anaconda. Same problem as @user6904670 said,

kill running python.exe

and Close Anaconda.exe and other related process

回答3:

Run the cmd window as administrator (https://technet.microsoft.com/en-us/library/cc947813(v=ws.10).aspx)

回答4:

pip install PyQt5

Syntax is not right for PyQt5 because PyQt5 is not compatible with pip, So you have to use pip3. use this command

pip3 install PyQt5

Read this article for more information official http://pyqt.sourceforge.net/Docs/PyQt5/installation.html

回答5:

If your Python 3.x was installed to its preferred (default) location C:\ Program Files \Pyton3x and if you are running your code not with elevated privileges in OS (not as administrator), then consider giving all user permissions to Python installation folder.

回答6:

I had the same problem. If you have Anaconda install try conda navigator and pip
