I’m stuck on Stage #MG5.

When ran locally:

```auto
PATH="/usr/bin:/usr/local/bin" ./your_shell.sh

```

Output:

```auto
Tokens:
/usr/bin
/usr/local/bin
$ type ls
ls is /usr/bin/ls
$

```

Here are my logs:

```auto
Initiating test run...

⚡ This is a turbo test run. https://codecrafters.io/turbo

Running tests. Logs should appear shortly...

Debug = true

same here…  
locally it works fine, but when I try with “codecrafters test” or with git it gives me the same error.

Hey everyone,

Thanks for reporting this! Can confirm that this is an issue with how our test runner environments are built, we’re looking into this…

This should be fixed now!

Will keep this open until someone confirms the fix worked for them 🙂

The tests appear to be functioning correctly. Although there is a warning related to loading internal components.

It could be a issue within my code, but the last test is failing. Is the test is looking for the “my\_exe” executable in my local/project directory?

```auto

Getting the “runtime/cgo” loading error too, but it passed all the tests so guess there’s something wrong in your code (I’m using linux so I don’t know, maybe mine won’t work too in Windows!).

I am on Linux (Pop os). I will check my code, maybe I missed something.
