• How did you install nvm? (e.g. install script in readme, Homebrew):
  wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.8/install.sh | bash

nvm says 'no .nvmrc file found' when the problem is that the version inside of said .nvmrc is not installed.

I have a systemd service that calls nvm like this.

/home/kenny/.nvm/nvm-exec nodemon ./src/index.js

the output was:
Mar 31 21:06:00 vm5 start.sh[3021]: No NODE_VERSION provided; no .nvmrc file found

the contents of the .nvmrc file are:
v9.7.0

The error disappeared after running nvm install 9.7.0 --reinstall-packages-from=node

I got the thing to work but I want to inform you that the error message is wrong it should say that the version inside the .nvmrc is not installed, not that there is no .nvmrc file.

Thanks, this message should definitely be improved.

I've run into this a couple of times as well. It would have helped me if nvm-exec just didn't suppress the error message from the failing nvm use command.

Also, this particular instance of the problem could be sidestepped by nvm-exec running nvm install instead of nvm use. Maybe it could support an --install switch similar to nvm use --install?

[ljharb]

nvm use --install isn’t a thing, because you can always nvm install to get that behavior. Since nvm-exec doesn’t have that choice, an install option for it might make sense.

nvm-exec isn’t the primary use cases for nvm, so it makes sense to me that this hasn’t come up yet, but I’d accept a pr that improved the error message for nvm-exec as well.

Ah, sorry, I meant nvm.sh --install.

Sounds good!

For the record, my use case for nvm-exec is a launch config for the vscode debugger so that the node version specified by the project's .nvmrc gets picked up: microsoft/vscode#16173 (comment)

This has not been fixed yet.

1. create foo/.nvmrc with v10 in it
2. cd foo
3. ~/.nvm/nvm-exec npm

expected: nvm-exec to complain that v10 is not installed
actual result: No NODE_VERSION provided; no .nvmrc file found

[ljharb]

@bf yes, the issue being open indeed means it has not been fixed yet :-)

[userwiths]

Hey, I tried to see if I could fix this one real quick.
After reading for some time through the code managed to get it to behave better on my local (Linux Arch) machine and display a more expressive message in case the versions differ.

Knowing this is a big project and heavily relied on would be glad to hear if this could be improved enough to resolve this issue or if it is even in the right direction.

Sample result with v10 installed

@khs1337 nvm-exec isn't meant to be ran directly. nvm is a sourced shell script, and then you'd run nvm install to auto-install and use the .nvmrc version.
