ERROR - packages.json parsing error, after removing npm-container


I tried out meteorhacks:npm but decided to remove it, and now every time I run meteor, this happens:

ERROR: packages.json parsing error [ ENOENT, no such file or directory ‘/Volumes/Extra/Sites/test/packages.json’ ]

I can’t seem to get rid of it, despite meteorhacks:npm and npm-container both being removed. Why is it still looking for this file?
