[DaggieBlanqx]

As I was running the node install,I encountered this :

e:\projects\farajaarts>npm install pesajs

node-expat@2.3.16 install e:\projects\node_modules\node-expat
node-gyp rebuild

e:\projects\node_modules\node-expat>if not defined npm_config_node_gyp (node "C:\Users\Me\AppData\Roaming\npm\node_modules\npm\bin\node-gyp-bin\....\node_modules\node-gyp\bin\node-gyp.js" rebuild ) else (node "" rebuild )
