bug: Cannot create a Ionic 5 project

[Sampath-Lokuge]

Hi,

Ver: Ionic 5

I have tried many ways. But none of them worked.

ionic start

and

ionic start ngrx sidemenu --type=ionic-angular

Error:

of core-js@3.

Now it's around 5 H. But still the same error.

Hi @Sampath-Lokuge,

To start a v5 app, use --type=angular. the ionic-angular type is for v1 projects that use AngularJS, which it looks like there is a dependency that needs to be updated for those older starters.

Hi @elylucas

Still the same issue. This is not working with the ionic start too.

[elylucas]

Hmm, weird because [email protected] definitely exists: https://www.npmjs.com/package/error-ex/v/1.3.1

Can you make a request to https://registry.npmjs.org/error-ex/-/error-ex-1.3.1.tgz and see if it downloads the file?

Do you have any custom npm setup through a .npmrc file or anything similar?

No.

Looks like there is a problem with npm serving up 404s for some packages right now, including error-ex:

https://status.npmjs.org/

Looks like they discovered the issue and fixed it, but it might take some time to propagate. Let us know if its still having issues after awhile.

[Sampath-Lokuge]

Sure. I'll try it few hours later and update this post. Thanks.

[erikyuzwa]

just a +1 for encountering this same issue as well. Thanks for the mention of npm status @elylucas

[Sampath-Lokuge]

Still this is not working. NPM says all are working fine on the above URL. But it is not. I'll try again later.

Same situation here!
npm ERR! 404 Not Found: error-ex@^1.3.1

[amanuppalhp]

Here is a temporary solution:

npm i https://github.com/Qix-/node-error-ex
npm install

Found here: [(https://github.com/facebook/create-react-app/issues/8465)]

I close this since now it is working fine.
