Hi @thousandsofraccoons,
have you installed typescript as a devDependency in your project?

[multipliedtwice]

yes, nextjs adds it by default if --typescript flag is specified

[ivanhofer]

can you try to install typescript as a global dependency?
npm install - g typescript

Strange.
@thousandsofraccoons can you please try to install typesafe-i18n via

npm install typesafe-i18n

and then run it from within the node_modules folder:

./node_modules/typesafe-i18n/cli/typesafe-i18n.mjs

Hi!
Had the same problem.
I ran:
npm install typesafe-i18n
./node_modules/typesafe-i18n/cli/typesafe-i18n.mjs
the last command hangs so in 'control+C'ed it
then:
npx typesafe-i18n --setup-auto
and it seems to solve the problem

[ivanhofer]

What operating system are you using?
Which version of node?
Which version of npm?

[jeromecc]

• Debian 11
• Node.js v14.18.2.
• npm 6.14.15

I'm not sure but I think the problem is that npm version < 7.x.x does not install peerDependencies. This was added in version 7.

I can't add typescript as a devDependency because I need the generator to create the types for the TypeScript version you are using in your project. If I would include typescript, then types could be generated, you project does't support yet.

I'll update the Documentation and mention an alternative way to install typesafe-i18n

I have added a troubleshoot section to the docs: https://github.com/ivanhofer/typesafe-i18n#installing-typesafe-i18n-fails

Feel free to reopen this issue if you still encounter some probplems when installing typesafe-i18n.
