reported stackframe provide wrong line number (on Windows) #1055
Description
Expected Behavior
Expecting ts-node to report accurate stack frame, pointing to the original typescript file.
Steps to reproduce the problem
package.json
{
"name": "tsnode-issue",
"version": "1.0.0",
"main": "index.js",
"dependencies": {
"typescript": "^3.9.3"
}
}
test.ts
/* some comment */
function someFunc() {
throw new Error("Error");
}
; (() => {
try {
/* some comment */
someFunc();
}
catch (err) {
/* some comment */
console.log("Error Found", err);
}
})();( no tsconfig file necessary)
Minimal reproduction
- run
$ npx ts-node@8.10.0 test1.ts - observe the result
npx: installed 8 in 2.249s
Error Found Error: Error

now run with older version

observe the result

- spot the that the stack frame is wrong
at c:\temp\tsnode-issue\test1.ts:9:9incorrect with ts-node@8.10
where it should report
at c:\temp\tsnode-issue\test1.ts:8:9'(correct with ts-node@8.9
In real production, the line number discrepancy can be large and annoying as it make it almost impossible to identify where the exception was raised ( annoying when doing TDD)
