Can't update meteor from checkout?



I’m using meteor to build an app with two other developers. we are developing on windows10 x64 and installed meteor using the windows installer. I now upgraded my local meteor version from 1.3 to 1.4.2 and committed and pushed my changes. Even without pulling my changes, the others try to perform meteor update but get the message:

‘You are running Meteor from a checkout, so we cannot update the Meteor release’

so I thought, well okay let’s try a specific version but than the message was:

Can’t specify a release when running Meteor from a checkout.

the other dev even tried to remove meteor and reinstall it but that didn’t solve anything. remarkably the version installed again was meteor 1.3 and not 1.4

any idea how to fix this?
