It appears that particular dependency versions can cause this issue  For example  gulp-uglifycss 1 0 7 has this problem  see https   github com rezzza gulp-uglifycss issues 15    If you are allowing major or minor version updates in your packages json via   or    remove those characters thoughout the file and try another npm install  If it works that time then you ll be alright after you have the fun of narrowing down which package is causing the problem

IMPORTANT  The solution below is now regarded as unstable  and you should use Node Version Management instead  Node Version Manager on Github  David Walsh also has a good introduction to NVM  NVM works beautifully and I ve been using it to manage legacy WordPress projects for a few years     Please don t use this - use NVM  I just had this exactly issue when trying to install the Sage theme for WordPress  When I ran npm install on the theme directory  it failed   Looking in the dependencies in package json  I could see that the engine I was running for Node was out of date  Running node -v on the command line showed that I was on v0 10 9  and the latest version of Sage requires    0 12 0  So here s the fix for that  These steps are from David Walsh s blog   Clear your npm cache  sudo npm cache clean -f Install the latest version of the Node helper  sudo npm install -g n Tell the helper  n  to install the latest stable version of Node  sudo n stable   You should then get a progress display  after which you will be up to date   When I ran npm install after doing this  everything worked fine  and I was able to run gulp to build the initial dist directory
