ng build failed :

I am filing a bug when I execute the command “ng build” since I been updated to version 0.0.27 (no worries in Version 0.0.26)

user@computer c:\dev\project\project_name $ ng build BuildingCannot read property 'push' of undefined TypeError: Cannot read property 'push' of undefined at addPathRecursive (c:\dev\project\project_name\node_modules\angular-cli\lib\broccoli\angular2-app.js:54:23) at c:\dev\project\project_name\node_modules\angular-cli\lib\broccoli\angular2-app.js:58:11 at Array.forEach (native) at addPathRecursive (c:\dev\project\project_name\node_modules\angular-cli\lib\broccoli\angular2-app.js:57:34) at Array.forEach (native) at Angular2App.toTree (c:\dev\project\project_name\node_modules\angular-cli\lib\broccoli\angular2-app.js:51:31) at module.exports (c:\dev\project\project_name\angular-cli-build.js:13:16) at Class.module.exports.Task.extend.setupBroccoliBuilder (c:\dev\project\project_name\node_modules\angular-cli\lib\models\builder.js:57:19) at Class.module.exports.Task.extend.init (c:\dev\project\project_name\node_modules\angular-cli\lib\models\builder.js:91:10) at new Class (c:\dev\project\project_name\node_modules\core-object\core-object.js:18:12)

If you want more information do not hesitate. Thanks

Hi, if you don’t have Python in your system then try installing it.

ng init is just like ng new but in existing folder.

“Are we supposed to run this whenever there’s a new version of angular cli?” No, of course not, but we are working on the new (faster) build system and some of the latest versions might have issues.

I will test this later today on Windows and report it under this issue.
