Ionic2 RC0 & > build error

Trying to use with Ionic2. Installed via $ npm install --save and the typing via $ typings install --save --global

Using ionic serve it works fine, but when trying to build for ios, I get an ngc error, saying:

[23:29:28]  ngc: Error: Error at /Users/floriannorbertbepunkt/Dropbox/Dropbox Arbeit/Mister Bishop Studios/Ionic Tests/myApp/.tmp/providers/backandService.ts:72:21: Cannot find namespace 'SocketIOClient'.

[23:29:28]  ngc: Compilation failed

Does anyone got working with RC0 and can tell me what I’m missing here?

Issue solved. If others have the same problem, please take a look here:

It seems like correct typings for were not installed. You can do this with

npm install @types/node --save-dev --save-exact
npm install @types/ --save-dev --save-exact
