Using 'nvm use'

[polderudo]

I have a smal script that should use 'nvm use' to set the npm version before building some frontend.

I use
local_shell: /bin/bash

and also use a shebag

- name: build vue
  options: {local: true}
  commands:
    - name: del dist folder
      script: rm -rf $FRONTEND_LOCAL_DIR/dist
    - name: build vue
      script: |
        #!/bin/bash
        cd $FRONTEND_LOCAL_DIR
        nvm use
        npm run $NODE_BUILD_TARGET

but the task runs into error:
[localhost] > /bin/sh -c /tmp/.spot-5237875189867584512/spot-script3544141793
[localhost] ! /tmp/.spot-5237875189867584512/spot-script3544141793: line 10: nvm: command not found

nvm is not availabe in sh, only bash and zsh.
Any idea why the script does not use bash from the shebag but sh?

This is not about sh, the /bin/sh -c part you see above is just invoking the generated shell script which should have the proper #!/bin/bash shebang.

Adding --dbg and/or -v parameters to your command line will show you more details, but according to this error, looks like nvm is located in a place where the newly started bash can't find it. You can try to symlink it to some common place, like /usr/local/bin for example, or adjust the path resolution for bash.

One more thing - it is not specific at all to nvm use but to nvm: command not found (i.e. nvm itself)

[polderudo]

yes that is clear from the error message. Reading a little bit i found out, that nvm is implemented as shell function which is "created" in the .bashrc
/bin/sh -c
does not run in an interactive shell, thus the .bashrc is not used and thus nvm is not available.

Will try to figure out if this can be overcome.

script: |
          #!/bin/bash
          . ~/.bashrc
          cd $FRONTEND_LOCAL_DIR
          nvm use
          npm run $NODE_BUILD_TARGET

works. just source the ~/.bashrc :)
