npm install -g karma protractor bower http-server
on Windows 8.1 64bit was a bit painfull.
What finally worked was:
- install python 2.7 (3.x did not work)
- install Visual Studio 2015 and make sure C++ Compiler is installed
The last part I learned the hard way. For this error:
Could not load the Visual C++ component "VCBuild.exe"
Installation of .NET Framework did not helped. After installing Visual Studio 2015 Comunnity I got:
TRK0005: Failed to locate: "CL.exe"
Only reinstall with more options checked – worked.
