Numpy update fails with "Permission denied" error

Question

I downloaded the precompiled numpy binary from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy and tried to update the current numpy installation on Windows 7 using

 pip install --upgrade "numpy-1.10.4 vanilla-cp27-none-win32.whl" 

I get the following error:

 C:\Users\Jeroen\AppData\Local\Enthought\Canopy\User\Scripts\pip-script.py run on 04/01/16 13:20:05 Unpacking c:\users\jeroen\downloads\numpy-1.10.4 vanilla-cp27-none-win_amd64.whl Installing collected packages: numpy Cleaning up...

Additional information about the currently installed version of numpy on my system:

 Python 2.7.3 |EPD_free 7.3-2 (32-bit)| (default, Apr 12 2012, 14:30:37) [MSC v.1500 32 bit (Intel)] on win32 Type "credits", "demo" or "enthought" for more information. >>> import numpy >>> print numpy.__version__ 1.7.1 >>> print numpy.__path__ ['C:\\Python27\\lib\\site-packages\\numpy'] 

Answer 1

I removed both Enthought Canopy and EDP and then I was able to update numpy via pip .

Answer 2

I had the same message, and for me just need to close the eclipse before upgrading or reinstalling numpy. I don’t know why, but it can help people who have a similar problem, first make sure that everything is closed.

Answer 3

I had a similar error message when trying to upgrade numpy to 1.11. What worked for me was to delete the numpy folder manually from Lib / site-packages /, and then set the whl variable (via the CMD admin window) using the usual install install command.

Answer 4

• Turn off the Python process in task manager
• delete the file name "numpy \ core \ multiarray.pyd" (if any)
• open CTRL + SHIFT cmd
• Now try installing the package. It will be successfully installed.

Answer 5

Just close the IDLE windows, this works for me

Answer 6

There was the same problem. I solved it by contacting the command module as an administrator. Do it:

• Click Start
• Click All Programs
• Click Accessories
• Right Click Command Prompt
• Run as administrator

If the "User Account Management" dialog box appears, click "This is what you want."
