Error during installation of pip on win10

Question

i've run into some problems while trying to install pip on win10, I can't understand from where it's coming from, here's what the error looks like:

I run the command python get-pip.py --prefix=/usr/local/

And the cmd responded with an error:

Thanks if you know how to fix this. ANd feel free to ask anything you need to know.

Answer 1

Unfortunately, raise ValueError, "path '%s' cannot be absolute" % pathname is relatively generic as far as I am aware. You may wish to try python get-pip.py --prefix=/usr/local but that is just a guess.

However, you question raises more in my mind:

• pip is installed with Python in most cases, so why are you even running python get-pip.py?

• How did you install Python? C:\Python27 is usually associated with vanilla Python from Python.org in my experience. Did you get from Python there, from the Windows store or somewhere else (e.g. via Anaconda)?

• Why are you adding --prefix=/usr/local? /usr/local is a Linux directory and only makes (possible) sense if you are running under the Windows Subsystem for Linux (WSL). Is that what you are using?
