Wrong pip3 python location or new Version
#1
I'm in Ubuntu / Linux

I try to install python3.8.2 with the latest version.

before i install i had Version 3.5.2, and that works very well.

but now pip and pip3 is the same linked location:

pip -V
pip 20.0.2 from /usr/local/lib/python3.8/site-packages/pip (python 3.8)
pip3 -V
pip 20.0.2 from /usr/local/lib/python3.8/site-packages/pip (python 3.8)

the problem is why i can't install any packages with the new version error message says: **

sudo pip3 install nltk

**

I think the trace indicates that you need to run
pip3 install _ctypes

That was wrong. ctypes is a module, not a package.
You can see this for info on it:

https://docs.python.org/3/library/ctypes...ule-ctypes

but I don't know how to install packages, and that documentation doesn't say where to get ctypes or how to install it.

I wish the admin would enable editing or deleting of posts more than 10 minutes after posting, so I could delete my first stupid reply.

should say "I don't know how to install modules.'

I went back to try to edit this almost immediately after posting it, and it said I'd posted it 31 minutes ago. The timestamping is wrong, so we can't edit posts EVER, let alone within a 10-minute window of posting.

I'm testing to see whether clicking the "reply to" to the initial post makes any difference wrt posting time.

I'm testing to see if "New Reply" will give me a reply that I can then edit or delete.

Nope. Once you've commented on a thread, any new comments on it will be incorporated under your previous comment, so you won't be able to edit or delete them, ever.
