Error installing AutoitLibrary through command line - command-line

Question

I need to install robotframework-autoitlibrary to use on my test cases.
My problem is when I try to install AutoIt Library through command line with the following command:
pip install -U robotframework-autoitlibrary --no-cache-dir --pre
I have this error:
C:\windows\system32>pip install -U robotframework-autoitlibrary --no-cache-
dir --pre

Thanks for your help,

Answer 1

The error looks like the environment variable HOMEDRIVE is not set, even though it has a value according to your test (the library installer uses it to copy some files).
Can you try this - manually set it, and straight after that run the pip - in the same Command Prompt (cmd) session:
set HOMEDRIVE=C:
pip install -U robotframework-autoitlibrary --no-cache-dir --pre
