New to Blender. Experienced with Python 2.7.

I am trying to install pip in my Blender Python implementation. I am attempting to do this by following the instructions in How to use PIP with Blender's bundled Python? - Answer, which links to Install pip.

I followed those instructions, and it seemed to be going well, but I got a PermissionError. I switched from doing it cmd.exe to PowerShell, but encountered the same problem.


What do I need to do to get past the PermissionError?

Here is the full output from the command execution, including the exception message:

    $\begingroup$ I'm voting to close this question as off-topic because it's not about Blender, but about an operating system issue... $\endgroup$ – m.ardito Jan 31 '18 at 7:06

    $\begingroup$ were you running the cmd with administrator rights? $\endgroup$ – David Jan 31 '18 at 14:41
  • $\begingroup$ m.arito, can you give me a chance. How am I supposed to know it is an os issue? It has only happened to me while working with Blender. Voting to close it is saying I didn't understand the answer to my question well enough before I asked it. $\endgroup$ – philologon Jan 31 '18 at 15:44
  • $\begingroup$ David, I thought I was, but I was mistaken at the time. My best solution (see my own answer, below) turned out to be to reinstall Blender at a different location. I needed it out of C:\Program Files\ anyway for other reasons. Doing this eliminated the administrator privileges issue. $\endgroup$ – philologon Jan 31 '18 at 16:39

On Windows 7, I go to the start menu, type cmd, when cmd.exe pops up, I right-click that and choose 'Run as administrator'. This solves the permission errors. Here's a guide for how to do it on Windows 8.1, see method 1.


Away from this forum, a colleague suggested I reinstall Blender to a location other than C:\Program Files.

I tried his suggestion, and it works fine.

Problem resolved.
