npm link "The file is marked as an executable but could not be run by the operating system."

Question

So I made a cli with package.json that specifies a bin file.

I npm link'd it. Then I created a new folder on my desktop and npm link foocli which installed it fine to that directory's node_modules folder.

Then I try to run the cli from that dir and it throws:

The file '/usr/local/bin/foocli' is marked as an executable but could not be run by the operating system.

Any idea what's causing this and how I can fix it?

Do you have #!/usr/bin/env node as the first line of your executable file? – Thaliathalidomide

Ah! That was it. I'm an idiot. I had it in there, but went to redo the entire file and erased everything and forgot to add it back. Thanks! – Mailer

Answer 1

#!/usr/bin/env node is needed at the top of the file that is being executed so the shell knows how to execute the file.
