Nodemon TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" #2155

Closed i-Lucas closed 6 months ago

i-Lucas commented 6 months ago

Hello. I noticed that this problem happens when I am using a node version higher than 18.17.0 LTS

The error occurs when executing the command 'nodemon filename.ts'

Nodemon TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts"

System: Ubuntu 22.04.3 LTS. nodemon: ^3.0.2 docker: no

When changing the system node version to v18.17.0, the nodemon executes the .ts file normally.

And if you repeat this test without nodemon and use node (or TS or what have you) directly, what do you see? (If it repeats - you'll need to include information to replicate)

This issue is related with ts-node. Take a look at this thread; https://github.com/TypeStrong/ts-node/issues/2094

I fixed it by running like below; nodemon --exec node --loader ts-node/esm .filename.ts

node version: 20.10.0

@Salamante is this worth adding to the FAQ or is this a bug in ts-node?

Salamante commented 6 months ago

@remy I think It's safe to say this is a bug in ts-node.
