Post Install Script Fails in 7.2.0 version due to yarn dependency missing

Post install script fails for 7.2.0 version. It uses yarn. Our source doesn’t use yarn to manage its dependencies. 7.1.1. didn’t have this script.

Console Output -

Expected Behavior

Backward compatibility. If yarn is not available use npm.

Current Behavior

Expects Clients to have yarn as a dependency to run its post install script.

Possible Solution

Not use yarn or use npm if yarn not available. Or add yarn as a dependency.

Steps to Reproduce

1. Run post install script. Don’t have yarn as a package manager

Environment

Node

Thanks for the notice guys. Should be fixed in 7.2.1 now.

Is it really needed to install documentation dependencies if amplitude-js is transitive dependency?
