👍 I am experiencing the same issue on Ubuntu Linux 16.04

[boardman]

Same issue on OS X 10.11.6

[Bulan]

Had the same, resolved with:
npm install

[elvirdolic]

yep same issue

[FabienDehopre]

@Bulan npm install is a temporary workaround. ng init should work without installing npm packages manually as previous versions did.

[jjstreet]

I just want to add that performing ng init after npm install does not provide a list of diffs to the user. Angular-cli simply tells you:

It seems like you're using a project generated using an old version of the Angular CLI.
The latest CLI now uses webpack and includes a lot of improvements, include a simpler
workflow, a faster build and smaller bundles.

To get more info, including a step-by-step guide to upgrade the CLI, follow this link:

Is this a bug that needs to be fixed? If so when will it be fixed?

[filipesilva]

@FabienDehopre just to confirm, did you follow the whole procedure as indicated in https://github.com/angular/angular-cli#updating-angular-cli, including deleting node_modules and doing npm install --save-dev angular-cli@latest?

npm uninstall -g angular-cli
npm cache clean
npm install -g angular-cli@latest
rm -rf node_modules dist tmp
npm install --save-dev angular-cli@latest
ng init

[norricorp]

Hi Filipe,
yes I did all of that and then got the error message on ng init.

@filipesilva yes, I did follow the whole update procedure. And I succeed to reproduce this issue on another project.

[xtreemrage]
