Source Diff: Error: EISDIR: illegal operation on a directory, read

Summary

I want to use the Source Diff feature in VSCode.

When I follow the instructions:

sfdx plugins:install @salesforce/sfdx-diff

I get this error:

$ sfdx plugins:install @salesforce/sfdx-diff This plugin is not digitally signed and its authenticity cannot be verified. Continue installation y/n?: y Finished digital signature check.

I ran into this issue and was able to resolve it by deleting the yarn.lock folder in C:/Users/Me/AppData/Local/sfdx/ manually and then re-running the install command.

I hope this helps anyone else running into this issue, it applies to any plugin installation.

We have updated the Source Diff commands in VS Code. You no longer need a CLI plugin. Check out the documentation for more details.
