Need to use recently docker, Long ago run The container of , Want to run A similar , Then I found it runlike library , Requirements can be fulfilled .runlike It's a python The library of , But the execution is directly in bash Internal input runlike Executive . However, the actual operation encountered Command not found.

At first, it was speculated that python2 and python3 Problems with multiple versions , But in fact, it's not . The general reason is linux Next , Executable scripts are put into  ~/.local/bin This directory . However, this directory has not been added PATH, So lead to bash The program couldn't find runlike. Students who are not familiar with script programming can add PATH Relevant knowledge .

Maybe the wrong roast ：Python2 Total abandonment ,Python3 Many versions stop supporting 2022 year ,Ubuntu Use pip and python And mark python3 perhaps pip3, tired .

Roast again ： What does the quality of the new article suggest ……It looks like it discriminates against blogs with less than 1000 words.
