I have updated my sfdx to latest version

 nagendrasingh@Nagendras-MacBook-Pro javascriptfndemo % sfdx  version
 sfdx-cli/7.121.8 darwin-x64 node-v14.18.0

Ny node version and npm version both are good as per requirement.

nagendrasingh@Nagendras-MacBook-Pro ~ % node --version
nagendrasingh@Nagendras-MacBook-Pro ~ % npm -version

I have also installed docker for mac for desktop.

But when I run sf function locally, I see an error.

nagendrasingh@Nagendras-MacBook-Pro javascriptfndemo % sf run function start -p 8080 -b 9229

Building javascriptfndemo Error: spawn /usr/local/lib/node_modules/@salesforce/cli/node_modules/@heroku/functions-core/bin/benny-darwin ENOENT Code: ENOENT

Has anyone faced this issue?

FYI (Update) Works perfectly fine with windows system

  • I'm getting another another on windows too.

    Maybe there is some issue starting the function from cli. I just did start it right from the docker & invoked it from code. It worked! Commented Oct 13, 2021 at 6:17
  • Invoked it from code, what do you mean by this? I thought functions are not yet available in any org. You can only invoke it locally with docker. Commented Oct 13, 2021 at 7:52
  • That's correct. Instead using Start Function from cli. Open Docker & you'll see start button, just start it from their. I'm sure we're missing something that's why it doesn't work with cli. Commented Oct 13, 2021 at 8:13
  • How where you able to push the function to docker? Commented Oct 13, 2021 at 8:43

It was a permission issue, I installed npm with sudo, which is not a recommended way. I uninstalled node and reinstalled it using brew, https://changelog.com/posts/install-node-js-with-homebrew-on-os-x

And now it works fine. I am able to run functions locally in MAC too without an issue.
