I am trying to set a default org in VScode but it is not working. I get a Cannot read property 'getInstance' of undefined error.

ERROR running force:auth:web:login: Cannot read property 'getInstance' of undefined

Command : sfdx force:auth:web:login --setalias test --instanceurl https://test.salesforce.com --setdefaultusername

Output : ERROR running force:auth:web:login: Cannot read property 'getInstance' of undefined

Can anyone please help with this.


Usually this kind of issues are due to sfdx updates by salesforce, first step would be to updating SFDX with sfdx update command.

If that doesn't work, try to uninstall the salesforcedx Plug-In with below command and install it again.

sfdx plugins:uninstall salesforcedx

Edit: There is an issue on Salesforce CLI github project which mentions this.
