Error on build after `dojo create`

[gavinr]

Bug

I think this is a bug, but maybe just something about my environment. When I create a new dojo2 app using dojo create --name XYZ and then try to build (dojo build) I get an error:

ERROR in ./src/widgets/HelloWorld.ts
Module build failed: TypeError: Cannot create property 'version' on boolean 'false'
    at updateFileInCache (C:\...\temp\node_modules\ts-loader\dist\index.js:101:21)

    at Object.loader (C:\...\temp\node_modules\ts-loader\dist\index.js:21:12)
 @ ./src/App.ts 15:19-50
 @ ./src/main.ts
 @ multi ./src/main.css ./src/main.ts

• I'm on Windows 10.
• npm version 5.3.0
• node version 6.10.3
• dojo cli version 2.0.0-beta2.2

Expected behavior:

There should be no error an the example app should be built.

Actual behavior:

Error shown in terminal.

@gavinr Thanks for raising the issue, this is due to a release of ts-loader and the fact that the version of cli-build-webpack currently used in the template for create-app isn't pinned to a working ts-loader version.

To work around the issue you can install the previous version of ts-loader using npm i ts-loader@2.3.1 until we have released a new version of create-app (that we are working on doing now).

The PR with the changes to pin the build dependencies is here: https://github.com/dojo/cli-build-webpack/pull/182

[agubler]

We have just released a patch for latest and beta1 version tags, so hopefully this should now work if you re-install the dojo/cli and try create another app.

Running the following worked. Thanks for the quick response @agubler!

npm uninstall -g @dojo/cli
npm install -g @dojo/cli
