Install Python library in QGIS as non-administrator

Question

I would like to install the Python library in QGIS, but I have no administrator rights. Unfortunately, each solution found refers to the simplest installation via osGeo4W, which requires running as an administrator:

Even if I choose the other option by typing python code in the console like:

 import subprocess
 subprocess.check_call(['python', '-m', 'pip', 'install', 'openpyxl'])

Installing 3rd party python libraries for QGIS on Windows

it will still throw the

Error13: Permission denied

With respect to this situation, I am wondering about the completely manual way of providing the Python library to the QGIS root folder, for instance via simply copying the files from other root directories (i.e. from IDLE Python, where I could install everything without the problems).

Is there any way, which would allow w me to expand the Python library in QGIS without admin rights?

UPDATE:

As per the hint below:

https://www.geeksforgeeks.org/how-to-install-openpyxl-in-python-on-windows/

I've entered this link and followed the steps, but it looks like it's still not valid for QGIS. I've chosen the Folium library as an example. The installation has proceeded very well, although it's still not recognized in PyQGIS.

UPDATE II:

Unfortunately none of the hints below work.

Regarding the first one, the situation looks like this:

The second one presents below:

Maybe I have different path or something?

Answer 1

Since you don't have admin privileges, when you install a package using QGIS Python Console/Editor as follows, it is installed to C:\Users\user\AppData\Roaming folder.

import subprocess
subprocess.check_call(['python', '-m', 'pip', 'install', 'folium'])

Therefore, if you add this folder to the path in your script, you can import the package.

import sys
sys.path.append(r"C:\Users\user\AppData\Roaming\Python\Python39\site-packages")

import folium

Answer 2

Thanks to the earlier answer, I found another workaround for the issue in the case, when you might have a situation like mine (read Update II).

The steps are:

1. Download your Python library from the pypi.org website

   

2. Convert files optionally to .zip extension, i.e. by using the https://cloudconvert.com/gz-to-zip

3. Copy the .zip content to the following directory:

   C:\Users\user\AppData\Roaming\Python\Python39\site-packages
   

4. Run the following code:

   import sys
   
   sys.path.append(r"C:\Users\user\AppData\Roaming\Python\Python39\site-packages\sgp4-2.21")
   
   import sgp4
   

In the sys.path.append, remember to use the correct folder with your python library as it appears in your zip file.

Then everything should be alright.
