Nvm on Windows

Hello:

I’m trying to downgrade the node environment in a windows executor. Specifically, my configuration looks like this:

version: 2.1
orbs:
  win: circleci/windows@2.2.0
jobs:
  build:
    executor:
      name: win/default
      shell: bash.exe
    steps:
      - checkout
      - run:
          name: Install NVM
          command: choco install nvm
      - run:
          name: Install Node 11.15.0
          shell: bash.exe
          command: |
              set +e
              touch $BASH_ENV
              echo 'export NVM_DIR="$HOME/.nvm"' >> $BASH_ENV
              echo '[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"' >> $BASH_ENV
              echo 'nvm install v11.15.0' >> $BASH_ENV
              echo 'nvm use v11.15.0' >> $BASH_ENV
              echo 'node --version' >> $BASH_ENV
      #- run: npm install
      - run:
          name: Verify Node Version
          shell: bash.exe
          command: node --version
workflows:
    build:
      jobs:
        - build

When these builds are run, the job “Verify Node Version” results in:

Now using node v11.15.0 (64-bit)
/tmp/.bash_env-5e616cc5c8ed5d059c07c545-0-build: line 6: node: command not found
bash: node: command not found

Exited with code exit status 127

However, when I SSH into this machine, I can run node --version without issue, and it gives me 11.15.0. Thoughts on what I might be doing incorrectly here?
