       > ws@0.4.21 install /tmp/build_ngyi26sy7e54/node_modules/socket.io/node_modules/socket.io-client/node_modules/ws
       > node install.js

       [ws v0.4.21] Attempting to compile blazing fast native extensions.
       [ws v0.4.21] Native code compile failed (but the module will still work):
       [ws v0.4.21] The native extensions are faster, but not required.
       [ws v0.4.21] On Windows, native extensions require Visual Studio and Python.
       [ws v0.4.21] On Unix, native extensions require Python, make and a C++ compiler.
       [ws v0.4.21] Start npm with --ws:verbose to show compilation output (if any).
