Blender 2.92 fails to install pip with get-pip.py

[chubei-oppen]

I'm using Blender 2.92 with bundled Python on Ubuntu 18.04. When trying to Blender: Start, pip installation failed with following message:

Traceback (most recent call last):

It looks like some problem within get-pip.py.

I later solved this problem using ensurepip, which comes with the bundled Python.

@JacquesLucke Would it better to try ensurepip before get-pip.py in this extension? I'll be happy to make a PR if you find it acceptable.

[JacquesLucke]

That seems acceptable. Feel free to make a pull request. The get-pip.py fallback will probably still be necessary. In the past I found that ensurepip is not always available.

I still hope that one day I can revamp the entire extension to improve dealing with these kinds of errors (e.g. by making the pip installation process more explicit when it doesn't just work)..

I also see that warning on Windows 10 20H2. it starts and then close and returns these errors. Failed at code 1

The terminal process "c:\Program Files\Blender Foundation\Blender 2.91\blender.exe '--python', 'c:\Users\romboutversluijs\.vscode\extensions\jacqueslucke.blender-development-0.0.14\pythonFiles\launch.py'" terminated with exit code: 1.

Terminal will be reused by tasks, press any key to close it.

also shows this error

I solved my issue, im more of an OSX user and being Admin is simply being Admin. WIndows is to complicated i think.

It was a permission issue. I solved the pip issue also, as well persmission issue to upgrade. Now set both blender and python folders to full control and it works.

Thanks, @schroef, that solved it for me.

[schroef]

Yes @stjseidel i did that but not for all users
