Unknown command "undervolt"

[gvgndr]

pip list outputs undervolt 0.3.0;
~$ pip check undervolt No broken requirements found.;
but $ pip help undervolt ERROR: unknown command "undervolt", and
so does sudo undervolt.
I'm using ubuntu 20.10.

Did you install undervolt for the user or root?

I assume you installed it in your userspace. Please check if your user python /bin is part of your $PATH
echo $PATH
should contain
/home/<user>/.local/bin
or whereever your python environment installs its packages to.

Yes, indeed, that is the output I get. In fact, ~$ undervolt works as expected,
but with $ undervolt --read I get

modprobe: ERROR: could not insert 'msr': Operation not permitted
Traceback (most recent call last):
  File "/home/andrea/.local/bin/undervolt", line 8, in <module>
    sys.exit(main())
  File "/home/andrea/.local/bin/undervolt.py", line 386, in main
    subprocess.check_call(['modprobe', 'msr'])
  File "/usr/lib/python3.8/subprocess.py", line 364, in check_call
    raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['modprobe', 'msr']' returned non-zero exit status 1.

What does this mean? Also, would it be better to install undervolt as root?
Thank you!

I'm certain it would be easier if you installed it globally.

have a look at this issue #46
There are suggestions on how to install and run undervolt.
