[AC-1047] titanium script ends in exception when Visual Studio is present.

Most of the ti cli commands end with: /******************************begin stack trace *********************************/ c:\Users\wnpr\AppData\Roaming\npm\node_modules\titanium\node_modules\longjohn\dist\longjohn.js:185 throw e; ^ TypeError: Bad argument at ChildProcess.spawn (child_process.js:915:24) /******************************end stack trace *********************************/ By using the debugger /******************************begin debugger call*******************************/ wnpr@GFT6841 ~/Documents/Titanium_Studio_Workspace/Todo List $ node-debug /c/Users/wnpr/AppData/Roaming/npm/node_modules/titanium/lib/titanium.js info Node Inspector is now available from http://localhost:8080/debug?port=5858 Debugging c:/Users/wnpr/AppData/Roaming/npm/node_modules/titanium/lib/titanium.js /******************************begin debugger call*******************************/ I was able to locate that at line 915 in child_process.js that the following call: var r = this._handle.spawn(options); failed whenever the "options" parameter looked as followings: /******************************begin options object*******************************/ options: Object args: Array[5] 0: null 1: "&&" 2: "powershell" 3: "-command" 4: "C:\ProgramData\Titanium\mobilesdk\win32\3.3.0.RC2\node_modules\titanium-sdk\bin\test_permissions.ps1" length: 5 .. cwd: "C:\Programms\Microsoft Visual Studio 11.0\VC" detached: false /******************************end options object*******************************/ This "args" attribute of the options object was what was causing the exception and it was being created by a function in the "windows.js" file at line 376. When I commented out the "powershell" attribute creation code, the exception went away.
