Parse error in import.meta.env assignment

[yamachi4416]

A parse error occurred in the code where writing to import.meta.env.
I am posting this to Q&A because I cannot determine if this is an issue with Vitest.
I would appreciate it if you could look into this.

Can you change it to following?

export function configEnv() {
  Object.assign(import.meta.env, {__config__ : true});
  return true
}

If not, feel free to file bug report about this. It's related to how Vitest internally transforms import.meta.env.

The suggested workaround works. An issue will be opened for visibility.
Thank you so much for the help!
