This works for me: re-set the chown permissions of /.meteor/local/build (to avoid use sudo) to your user.

For example, my user is "skozz". In my project folder:

sudo chown -R skozz .meteor/local/build

Then run mrt or meteor

If the problem persists maybe you should set the same permissions to the main .npm folder. In my case:

chown -R skozz ~/.npm

I searched some more on the topic and it appears to be a problem with using sudo to install some packages which meteorite requires. As suggested on this Github issues page one way to solve this is to remove the folder /.meteor/local/build in the application and restart meteor.

try

chmod +x /Users/username/Dropbox/LearnSoftware_and_Math/LearnJavascript/LearnMeteor/microscope/.meteor/local/build/app/collections/posts.js

i solved the problem by completely removing purging uninstall ! nodejs and npm with this script 'os x' : sudo rm /usr/local/bin/npm sudo rm /usr/local/share/man/man1/node.1 sudo rm /usr/local/lib/dtrace/node.d sudo rm -rf ~/.npm sudo rm -rf ~/.node-gyp sudo rm /opt/local/bin/node sudo rm /opt/local/include/node sudo rm -rf /opt/local/lib/node_modules sudo rm -rf /usr/local/include/node/

after that i installed nodejs properly with the pkg (i'm on os x) downloaded on the nodejs website and instaled it then all worked fine with meteor update and cd path/to/meteor/project ; meteor
