[split] PIP install error

[Larz60+]

Yes, I always use cmder, but tried my cmd and it accepts ls as well for whatever reason, and I must say I am
glad that it does.
I prefer the Linux commands, as I used Linux (or Unix) 90% of the time from the late 70's until at least 2004,
and then a mix after that. Besides, they just make more sense to me.
