bash: /home/--------/.local/bin/pip3: /usr/bin/python3: bad interpreter: No such file or directory-CodePudding

I recently had my python versions messed up as they weren't there in my /usr/bin. Now I have mostly gotten it fixed so when I type:

------@--------:~$ python3 
Python 3.8.5 (default, Oct 30 2022, 19:55:55)  [GCC 9.4.0] 
on linux Type "help", "copyright", "credits" or "license" for more information.

and when I type:

-----@-------:~$ python 
Python 3.8.5 (default, Oct 30 2022, 19:55:55)  [GCC 9.4.0] 
on linux Type "help", "copyright", "credits" or "license" for more information.

When I use the command pip3 however I get a weird error of:

-----@-------:~$ pip3 
bash: /home/jayakumar/.local/bin/pip3: /usr/bin/python3: bad interpreter: No such file or directory

I was told in another question to use python3 -m pip install instead but I get an even weirder error:

WARNING: You are using pip version 20.1.1; however, version 22.3 is available.
You should consider upgrading via the '/usr/local/bin/python3 -m pip install --upgrade pip' command.

Any thoughts on how to solve this? Also, I tried the /usr/local/bin/python3 -m pip install --upgrade pip suggestion and that bears the same error.

CodePudding user response：

You can see where your pip3 file is:

which pip3

That should tell you the full path, which is /home/jayakumar/.local/bin/pip3

You can view that file like this:

more /home/jayakumar/.local/bin/pip3

In the first line, notice that it has #!/usr/bin/python3 or That directive tells your system where to look for python executable, which is /usr/bin/python3

Seems like you don't have that executable. Looks like /usr/local/bin/python3 is available. You can try switching to that executable. Or you can also reinstall python3: sudo apt install python3 --reinstall

Hope this helps.
