Basic run on arch linux: can not find script/file

Grafana k6 OSS Support

Umm … I seem to be difficult! :slight_smile:

attempting a basic/simple execution via terminal in /tmp:

╭─    /tmp                                                                                                                                         ✔  at 15:31:17 
╰─ k6 run ./testk6.js

ERRO[0000] The moduleSpecifier "./testk6.js" couldn't be found on local disk. Make sure that you've specified the right path to the file.
If you're running k6 using the Docker image make sure you have mounted the local directory (-v /local/path/:/inside/docker/path) containing your script and modules so that they're accessible by k6 from inside of the container, see https://k6.io/docs/using-k6/modules#using-local-modules-with-docker.

works if given on STDIN:

was able to run via docker (not what id prefer tho):

docker run -it --rm
  -v /tmp:/scripts -v /tmp:/jsonoutput
  grafana/k6
  run --out json=/jsonoutput/k6out.json /scripts/testk6.js

Hi @czrpb, Welcome to the community forum :tada:

From the looks of it snaps can not access /tmp which is confirmed in this thread.

Given that the snap is also not official way we (the k6 team) are packaging k6 I would recommend … not using it.

Given that k6 is a single binary I would recommend just downloading it and putting it in ~/bin and removing it when you no longer need.

There is also k6 AUR, although again it is not official, so I would also not recommend it.

Hope this helps you
