Moderately new to linux, I’m running Lubuntu 18.4 bionic beaver
I want to install and run a program that requires python 3.7 with pip.
I finally got the program installed and running on windows.
Now I’m trying to get it setup on Linux

When I try to set up this program, and I type in the command, which contains “pip” I get an error telling me there is no pip.

I was constantly getting this error in windows. Turns out, my system, no matter how I set my environment variables, was using the wrong version of python, and cmd would not except version specific statements like “python3.7” or “python37”. I finally got that fixed by reinstalling it and checking “set python path” on the installer (I missed that the first time I installed it because I didn’t know what it meant).

Linux has no such GUI installer for python (at least none that I can find). But it does let me choose the speciffic version to run. If I type “python3.7” it tells me I am running Python 3.7.2
So that works.

By using this command “ls -ls /usr/bin/python*” it lists all versions and it tells me 3.7.2 is located at
/usr/lib/python3.7
OK, all other python versions are in /user/bin/

I installed pip via “sudo apt-get install python-pip”

Here’s the problem, when I run the command for this program, it is still telling me it can’t find pip.
I check the /usr/bin/ and there is pip, pip2, pip3
I’m guessing pip3 needs to be in the python3.7 folder. So I copy paste… and it tells me access denied.

In Windows, the python folder is called python37, inside of that folder is the python.exe file.
There are subfolders, one of them is named scripts, inside of there are three versions of pip: pip.exe, pip3.exe, pip3.7.exe

In linux, there is no file called python in the python3.7 folder, there is no sub folder called scripts, there is no file called pip, and I can’t move any of the pips from /usr/bin/ to /usr/lib/bin/python3.7/
because access is denied.

So, how do I get python 3.7.2 to run pip to execute a command?

Try the following:

After running the command you gave me, I try installing this program and it still says it can't find pip.
The exact error was:
python3.7: can't open file 'pip': [Errno 2] No such file or directory

Are you just trying to run pip from the command line? If not, what program are you trying to run? If the latter, please confirm whether or not pip is at least recognized at the command line.

OK what I’m trying to do is install a program from the command line.
The program is a script that extracts chat data from Twitch.tv streams (no it is not a hacking tool, and requires registration with twitch dev portal to have server permissions in order to function).
I know the program works on Win7.

The command I am doing is “python pip -m install -r requirements.txt”

To check that pip is installed, I just went to terminal and typed “pip”
It gave back a list of commands.

I typed “pip check”
It told me “no broken dependencies”

I type “pip –version”, It says:
pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7)

I type “pip3 –version”, It says:
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)

I need pip to run from python 3.7.2
I type in “whereis python” and here is a list of all python versions and directories:

python: /usr/bin/python /usr/bin/python2.7 /usr/bin/python3.6 /usr/bin/python3.6m /usr/bin/python2.7-config /usr/bin/python3.6m-config /usr/bin/python3.6-config /usr/lib/python2.7 /usr/lib/python3.6 /usr/lib/python3.7 /etc/python /etc/python2.7 /etc/python3.6 /usr/local/bin/python3.7m-config /usr/local/bin/python3.7m /usr/local/bin/python3.7 /usr/local/lib/python2.7 /usr/local/lib/python3.6 /usr/local/lib/python3.7 /usr/include/python3.6m /usr/include/python2.7 /usr/include/python3.6 /usr/share/python /usr/share/man/man1/python.1.gz /usr/src/Python-3.7.2/python

Turns out I was mistaken earlier on where 3.7.2 was located, anyhow, I go to that directory, and pip.py is in there at:
/usr/src/Python-3.7.2/PC/layout/support/pip.py

I don't know if that's the right version or right place for it to be.
