react-email: `email dev` command always fails on Windows

This has been fixed under react-email@2.1.0-canary.1, stable release soon!

There’s already a PR open for this issue, #1216, and here’s a patch as a quick workaround for now:

@bennyburrito So sorry for the late reply here, but seems like the latest canary release has this fixed.

See issue #1354 and release notes https://github.com/resend/react-email/releases/tag/react-email%402.1.1-canary.1.

this fixed it for me!

nvm node v18.17.1

Yes this has fixed. Many thanks 😃

@kapilrc The above issue you mention is the one that the patch and the PR #1216 fixes.

About the other issue you saw with the 1.x.x is something that used to happen here and there, so if you try enough I think it might not be an error.

@kapilrc Seems like you’re using the 1.x.x version for the CLI. If you use react-email@2.0.0 you won’t have that issue you are mentioning anymore. That being said this issue (#1225) is for the 2.0.0 version, not the 1.x.x.
