Hi

Maybe try 1.14.4

As 1.14.5 was my first v1 release I might did something wrong. Will check
tomorrow

Something weird I noticed is that on my computer, running npx docusaurus-init init website actually produces a v2 site instead of a v1 site.

But, the v2 site does not work due to a validation error:

Maybe this is a bug only I have for some weird reason...

Can you please tell me what's your package.json, and confirm you are on v1? Not only @jeffreyhawkins , but all of you please.

If you are on v1, is the error SyntaxError: Unexpected token ? are there additional info like a stracktrace, screenshot, or something to share?

[jeffreyhawkins]

I can confirm version 1.14.5 is in the package.json.

They only error I see is SyntaxError: Unexpected token (37:15) no other information is shown.

So, it is a bug introduced in this PR: https://github.com/facebook/docusaurus/pull/2331

The issue is on the Users page:

The v1 parser is Babylon v6, and v6 does not support React fragments. Replacing the fragment by a div or <React.Fragment> solves it.

I'm not going to upgrade Babylon in v1 but will release a fix soon so that v1 can be initialized without issue. Also will add some useful logs so that this kind of problem is easier to debug.

Will be fixed in https://github.com/facebook/docusaurus/pull/3213

Release 1.14.6, seems to work now
