yupp m facing the same bug

Apologies that you both are running into this.

I tried to reproduce and I was not able to. I'm using PowerShell with node v8.11.3 installed, and the latest workbox-cli v3.4.1. Are you using those versions, or perhaps an older version?

Also, can you reproduce it if you try running the wizard in a different directory?

i noticed that because of nodejs version
when i used nodejs version 10.* , i got the same error
but i removed nodejs 10.* and installed nodejs version 8.* and my problme solved

Okay, so this is pretty strange.

I've installed node v10.9.0 and have been able to reproduce some of the freezing when using PowerShell and the Node.js command prompt on Windows (I'm testing on a Windows Server installation, actually).

I can't reproduce the issue when using the Git Bash shell on Windows, so I think this is particular to shells that use Windows-style paths.

What seems to help is changing a few instances of asynchronous calls to their synchronous version. This gets a bit tricky, since the original source is transpiled with the regenerator runtime, to ensure that we support node v6.

is an example of one spot that causes hangs, and it progresses past that if I change the code locally to fse.statSync().

I'm going to debug more, and thanks for everyone's patience.

Quick update—bumping the dependency versions for the various libraries used by workbox-cli seems to fix it in my local testing. I'll file a PR, but since those dependency updates break node v4 support, it will have to wait until the next major release of Workbox.

@jeffposnick Any news on this? Facing the same issue and I see the PR is pending.
BTW: when I use Git Bash the wizard works fine, but the menu selection on it is horrible 😢

[jeffposnick]

Using workbox-cli@alpha on npm should pick up our 4.0.0 alpha releases now, which contain a fix.

Feel free to read the release notes and confirm that it's working for you now.

I encountered this running Node v8.1.0. Using nvm, I switched to Node v8.9.0 and issue was resolved.

        nvm install v8.9.0
        nvm alias default v8.9.0

I'm using

• Gitbash 2.19.1.windows.1
• Windows 10
• node v10.9.0

I experienced the same issue listed by the OP but switching to 4.0.0-beta.0 of workbox-cli fixed everything.

Same issue here. Workbox-cli wizard stops at the first question

• Window 7 professional
• git version 2.19.0
• workbox-cli 3.6.3

installing 4.0.0-beta.0 fixed everything.
