I tried to install gruntjs package via npm, but the command
npm install grunt --save-dev
received an error:
npm ERR! error rolling back Error: ETXTBSY, unlink '/home/me/www/public_html/test/try/node_modules/grunt/node_modules/lodash/lodash.js'
npm ERR! error rolling back grunt@0.4.4 { [Error: ETXTBSY, unlink '/home/me/www/public_html/test/try/node_modules/grunt/node_modules/lodash/lodash.js']

Trying to install gulp led to a similar error.
All that I try on a virtual machine with Ubuntu 12, my host-system is Windows 8.
