Macos – rvm: command not found MAC OX

commandmacosrvm

Really, I don't know what happened. Excuse me if this question is so NOOB, but I can't find the solution for this problem.

-bash: rvm: command not found

I tried this

curl -L https://get.rvm.io | bash -s — –version latest

but still nothing I need to see the ruby version for use the simplecov because it not works with older version from 1.9

It might because the terminal not having rvm shell configuration loaded.

Try following from your terminal:

$ source ~/.rvm/scripts/rvm

then

$ type rvm | head -n 1

If the output is:

rvm is a function

You may need to add "source ~/.rvm/scripts/rvm" to your ~/.bash_profile file

Use the subprocess module in the standard library:

import subprocess
subprocess.run(["ls", "-l"])

The advantage of subprocess.run over os.system is that it is more flexible (you can get the stdout, stderr, the "real" status code, better error handling, etc...).

Even the documentation for os.system recommends using subprocess instead:

The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function. See the Replacing Older Functions with the subprocess Module section in the subprocess documentation for some helpful recipes.

On Python 3.4 and earlier, use subprocess.call instead of .run:

subprocess.call(["ls", "-l"])

You can try netstat
```
 netstat -vanp tcp | grep 3000
```
For macOS El Capitan and newer (or if your netstat doesn't support -p), use lsof
```
 lsof -i tcp:3000 
```
For Centos 7 use:
```
 netstat -vanp --tcp | grep 3000
```
