Fix for Bad interpreter: Operation not permitted

Note to self

Sometimes I get this error on the macOS Terminal or when running my script from the CodeRunner app:

bash: /path/to/script: /usr/local/bin/node: bad interpreter: Operation not permitted

Quick fix

xattr -d com.apple.quarantine /path/to/script

xattr -d com.apple.quarantine /path/to/script

Reason

Text editors like OSX’s TextEdit, Textastic and CodeRunner sometimes lock the file. This command fixed it.

It also appears to happen when the editor (BBEdit) is changing the line-endings in the file to Windows CRLF format, instead of the *nix LF format. You can resolve this with the ‘dos2unix’ tool.

If you don’t have Homebrew installed, follow this guide.

Then in the Terminal run this command:

brew install dos2unix

brew install dos2unix

And to convert your file:

dos2unix /path/to/file

dos2unix /path/to/file
