Meteor - Constraints on package with unknown “top level”

Question

I meet many errors like this after merging an update from my fork source:

No version of standard-minifier-js satisfies all constraints: @2.6.0, @~2.5.2
Constraints on package "standard-minifier-js":
* standard-minifier-js@2.6.0 <- top level
* standard-minifier-js@~2.5.2 <- top level

When I open .meteor/packages , I see only standard-minifier-js@2.6.0 , and I don't know where the ~2.5.2 comes from. What does the message top level mean other than what's written in .meteor/packages ?

Answer 1

The second top level means meteor itself since I have downgraded meteor to 1.8.3.

meteor update --release 1.8.3 --all-packages fixed the problem.
