How do I reset the SFDX CLI Runtime Global Configuration Values?

Question

I had sometime back set the apiVersion CLI Runtime Configuration value globally for all projects to version 45.0 when I signed up for Spring '19 preview sandbox, using the command:

sfdx force:config:set apiVersion=45.0 --global

Now whenever I executed any SFDX command, I would see the following message in the console.

WARNING: apiVersion configuration overridden at "45.0"

While I could have overridden this again locally when say I proceed using future versions, but that would have required me to set this for every local project.

So, how do I reset the global configuration value to be applicable for all projects?

Answer 1

I had struggled to find this for a bit as I missed the section discussing this in the docs. I realized that the answer was in the same documentation CLI Runtime Configuration Values but was not clearly called out with respect to how to reset global values.

The documentation mentions:

To unset a configuration value, set it to no value. For example, to unset the instanceUrl configuration value:

sfdx force:config:set instanceUrl=

So utilizing the same approach, I was then able to reset the global apiVersion that I had set for my SFDX projects using the below command. Note that command to set any global value (using --global) can be run from either outside or within a SFDX project directory.

sfdx force:config:set apiVersion= --global
