fourseven:scss problems with meteor upgrade

Question

My current Meteor version is 1.3.4.3 running on MacBook with El Capitan, it failed to upgrade while loading fourseven: scss@ 3.3.3_3 with the error as in my other question

And this did not fix the error:
meteor remove standard-minifier-css
meteor add seba:minifiers-autoprefixer

So I did meteor remove fourseven:scss as I am not sure if I needed it and run the upgrade again but still the same error.

How can I fix it so the upgrade works? Thanks

$meteor update
  => Errors
while initializing project:

  While loading package fourseven: scss@ 3.3.3_3:
  error: Command failed:
  module.js: 340
throw err; ^
Error: Cannot find module '../'

edit

When I change the line fourseven:scss@3.3.3_3 in ./meteor/versions to fourseven:scss@3.4.2 and run the meteor update , I get the error

$meteor update
  => Errors
while initializing project:

  While downloading fourseven: scss@ 3.4.2...:
