I think it probably has something to do with https://github.com/nodejs/node/blob/master/tools/osx-pkg.pmdoc/02npm.xml#L9 but I don't actually understand how OS X installers work. cc @othiym23

Hmmm, could 63a628d#diff-649abfdda4cfccbe318266e0c9116701L3 have been this issue? That commit was scheduled for v4.0.0 but doesn't seem to have landed until v5?

[nicolabortignon]

+1 same os version and 5.0.0.
Can't reproduce with 4.2.1

[Fishrock123]

Looks like the commit is staged for v4.2.2 but has not landed in v4.x yet. 5652ce0

cc @jasnell

[Fishrock123]

On second look, that seems like just an identifier though...

[Fishrock123]

cc @nodejs/build for anyone who knows how the OS X installer works more

[jasnell]

@nicolabortignon ... I just want to be clear: you are not seeing this problem with v4.2.1 currently correct?

[Fishrock123]

@jasnell I did not have any issues with v4.2.1

From #npm irc:

othiym23: Fishrock123: yes, but if the installer only uninstalls the previous version before installing the new version if the manifest IDs match, that would account for the behavior everyone's seeing

[nicolabortignon]

@jasnell that is correct, 4.2.1 works like a charm.
