I tried replicating the environment similar to yours. I'm not quite sure why, but when you download hub and append to the $BASH_ENV something mucks with the path that messes this up. Below is a machine executor where I ran the following config

version: 2.1

orbs:
  gcp-cli: circleci/gcp-cli@1.8
jobs: 
  sample:
    machine: true
    steps:
      - gcp-cli/install
      - gcp-cli/initialize

workflows:
  sample_wf:
    jobs:
      - sample

After running this config, gcloud was sucessfully installed. I then ssh'ed onto the machine and ran your step to install hub manually and was then presented with the error.

Without spending a ton of time, I'm not sure if this is a problem with the way ~/google-cloud-sdk/path.bash.inc is sourced or the additions you made to $BASH_ENV. Could you provide some more context around how you encountered this? Was this working in a previous build with a different machine image or different orb version?

@nathanhleung - we are investigating some issues with pyenv in some of the machine images. However, the latest machine image appears to work as expected. You can set this by updating machine: true to

machine:
      image: ubuntu-2004:202010-01

machine: true still provides an old default image. This old default image is still 14.04 based. We are now expecting users to specify the version of machine images, see the updated docs for more details

@nathanhleung, you can thank @lokst for this fix. The issue is with the way the PATH is being updated here in your config, echo "export PATH=$(pwd)/bin:$PATH" >> $BASH_ENV needs to be echo 'export PATH=$(pwd)/bin:$PATH' >> $BASH_ENV. In double quotes the $PATH is being evaulated before its appended to $BASH_ENV, single quotes avoids this evaulation and ensures $PATH is the text appended to $BASH_ENV.

Thank you for the quick response!
