Nvm does not change Node version on machine

There are dozen of half solutions or automatically closed subject WITH NO definitive answers:

We need nvm to work for ALL commands not just while doing this:

      - run: 
          command: |
            export NVM_DIR="/opt/circleci/.nvm"
            [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
            nvm install 10
            node -v
            npm -v
            npm i -g npm@6.9.0
            npm -v

Right now any other step won’t get the correct node version!

I just spent a least 2 hours in trying different solutions… sshing in the machine is no good since nvm is loaded correctly when I ssh, that’s crazy… for such a simple thing :((

[phil-lgr]

@drazisil I implore you to provide us with a solution I can’t just put

command: |
            export NVM_DIR="/opt/circleci/.nvm"
            [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"

to all of my npm run commands!

Switch nodejs version on machine executor [solved] leads no where

[drazisil]

That’s very strange you don’t have access. At any rate, I should be able to come up with a fix, give me a couple mins please.

[phil-lgr]

is the nvm thing a known issue? why we can’t set nvm use 10 or nvm alias default 10 once?

Sorry, it’s driving me nuts

[drazisil]

It’s not a known issue that I’m aware of. I’ll run some tests in a bit to check, but let’s get you something working first.

[drazisil]

Add the following as an initial step. This should add the command to the file that runs for every step.

echo 'export NVM_DIR="/opt/circleci/.nvm"' >> $BASH_ENV
echo ' [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"' >> $BASH_ENV

[phil-lgr]

echo ‘export NVM_DIR="/opt/circleci/.nvm"’ >> $BASH_ENV echo ’ [ -s “$NVM_DIR/nvm.sh” ] && . “$NVM_DIR/nvm.sh”’ >> $BASH_ENV

I already tried, but I will retry

to be clear to run the above in a run block:

      - run: 
          command: |
            echo 'export NVM_DIR="/opt/circleci/.nvm"' >> $BASH_ENV
            echo ' [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"' >> $BASH_ENV

[drazisil]

Yep. Running some tests on my own right now as well. Machine executor, correct?

Edit: Sorry, not run: and :command together.

[phil-lgr]

yes machine, so nvm is found in other commands but:

steps:
      - checkout
      - run: 
          command: |
            echo 'export NVM_DIR="/opt/circleci/.nvm"' >> $BASH_ENV
            echo ' [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"' >> $BASH_ENV
      - run: nvm install 10
      - run: node -v
      - run: npm -v
      - run: npm i -g npm@6.9.0
      - run: npm -v
      - run: nvm alias default 10
      - run: nvm use 10
      - run: node -v
      - run: npm -v

at the last - run: node -v I still get the old one:

[phil-lgr]

so in a run: or command: ??

[drazisil]

Running some tests, please standby

[drazisil]

Ok, Thanks for your patience. The primary issue, I think, is the alias command has to mention v10, not 10. Nvm was throwing an error, but thanks to it returning 0 as an exit code, we mark the step green.

(To be clear, the step being marked success on a zero exit code is expected behavior)

nvm alias default v10 works. See the below build.

Here is my full config for posterity in case I nuke the repo, and the above thread is hard to follow,

version: 2
jobs:
  build:
  build:
    machine: true
    steps:
      - checkout
      - run: |
            echo 'export NVM_DIR="/opt/circleci/.nvm"' >> $BASH_ENV
            echo ' [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"' >> $BASH_ENV
      - run: |
          node -v
      - run: |
          nvm install v10
          node -v
          nvm alias default v10
      - run: |
          node -v

[phil-lgr]

thanks, trying now

[phil-lgr]

it seems that it is resolved, I got a failure on npm install but now it work… ok thanks marking as resolved!
