Installation failed on Windows 10

Hi, I have an issue during installing dependancies in CodeCombat project in master branch:
(Node version v6.12.3, npm 3.10.10)

Error

`npm ERR! Windows_NT 10.0.16299 npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "install" npm ERR! node v6.12.3 npm ERR! npm v3.10.10 npm ERR! code ELIFECYCLE

Could you please help me?

Esper isn't really needed for codecombat on the serverside, you could just remove the dependency from package.json and install again.
