[Bug]: Module Resolution Issue with ts-jest 29.2.4 and TypeScript ^4.x when using isolatedModules option

[Hoo93]

Version

29.2.4

Steps to reproduce

1. Clone my repo at https://github.com/Hoo93/ts-jest-bug.git
2. yarn install
3. run jest

Expected behavior

The tests should execute without triggering the TS6046 error when isolatedModules is enabled.

Actual behavior

With ts-jest 29.2.4 and typescript ^4.x, enabling isolatedModules causes the TS6046 error to occur, suggesting that --moduleResolution is not being interpreted correctly.

Debug log

It only throw
error TS6046: Argument for '--moduleResolution' option must be: 'node', 'classic', 'node16', 'nodenext'.

Additional context

This issue seems to be related to how ts-jest handles TypeScript’s moduleResolution when isolatedModules is enabled. It may be that the TypeScript compiler options are not being correctly passed or parsed in this configuration.

Environment

System:
    OS: macOS 14.5
    CPU: (12) arm64 Apple M2 Pro
  Binaries:
    Node: 22.4.1 - /opt/homebrew/bin/node

Duplicate with #4499 and we will release the fix in 29.2.5

besides, ts-jest and Jest 29 supports ts >= 4.8. If you are below 4.8, you should upgrade to 4.8 at least to be compatible

@ahnpnl Thank you for your answer!
I upgraded the TypeScript version to 5, and everything works well now.”
