Expected Behavior
ts-node should work with Typescript 7.0.2
Actual Behavior
ts-node crashes with the following error message.
It has broken our CI/CD pipeline since 16:00 UTC of 8 July which is exactly when Typescript 7.0.2 became publicly available. And we had to pivot typescript version to 6.0.3 to fix it.

Steps to reproduce the problem
Prerequistics: Debian linux with latest Docker
- In an empty dir, create
Dockerfile with following content
FROM node:24
RUN npm i -g typescript@7.0.2 ts-node@10.9.2
RUN touch tsconfig.json
RUN echo "console.log('Hello world')" >> helloworld.ts
CMD ["npx", "ts-node", "helloworld.ts"]
- In the same dir, run
docker container run $(docker image build . -q)
- It outputs the error message described above
- The container run also fails if you modify the 2nd line in Dockerfile to
RUN npm i -g ts-node@10.9.2 as ts-node pulls the latest Typescript (7.0.2) anyways.
- The container runs successfully and outputs
Hello world if you modify the 2nd line in Dockerfile to RUN npm i -g typescript@6.0.3 ts-node@10.9.2
