SublimeREPL FileNotFoundError(2, "没有这样的文件或目录：'python'")

Question

I'm new to linux and I've just started using Ubuntu 20.04 LTS to get a feel for it.

I installed the snap version of Sublime Text 3 from the software centre included and set it up like I would usually do on Windows (Install package installer, download a theme and then download SublimeREPL).

However, when I try to run it I always get the error

FileNotFoundError(2, "No such file or directory: 'python'")".

I looked to see if Python was installed and which one. I had Python 3.8.2 installed so I then proceeded to update it 3.8.4.

I then tried again to see if it worked but it still doesn't work.

How can I fix this?

Thanks,

Mr Purple

Answer 1

I recently also faced this problem. For any future users who also run into this, here's what I did:

open: home/username/.config/sublime-text-3/Packages/SublimeREPL/config/Python

From here open Main.sublime-menu. Edit the entries so that it is the same as this: https://gist.github.com/Hckmar9/e1cb87b67a9836db4d26#file-main-sublime-menu

All you need to do really is change python to python3 a few times in the file. Once you're done, save and close. Now try again on sublime and it should work fine.

Answer 2

With installing python3, the command that can be used for running python scripts is $python3 <script_path>.

If you look at sublimeREPL config file for python, you will see that it uses "python" command instead of "python3" and because of this, you have gotten that error. To solve this problem, you can use update-alternative command in linux to link "python" string to "python3". To do that, you can copy and paste the following command in your shell:

sudo update-alternatives --install /usr/local/bin/python python /usr/bin/python3 20
