ts-node: Does not work after upgrading to 4.0.0

ts-node just suddenly stop working after upgrading to 4.0.0 (The same with 4.0.1):

nodemon.json

{
	"watch": ["src"],
	"ext": "ts",
	"ignore": ["src/**/*.spec.ts"],
	"exec": "ts-node -P ./tsconfig.json --no-cache ./src/index.ts"
}

tsconfig.json

{
	"compilerOptions": {
		"target": "esnext",
		"module": "commonjs",
		"sourceMap": true,
		"lib": ["esnext"],
		"outDir": "build",
		"rootDir": "src",
		"importHelpers": true,
		"noEmitOnError": true,
		"strict": true,
		"noUnusedLocals": true,
		"noUnusedParameters": true,
		"noImplicitReturns": true,
		"noFallthroughCasesInSwitch": true,
		"moduleResolution": "node",
		"experimentalDecorators": true,
		"emitDecoratorMetadata": true
	}
}

nodemon: 1.12.5 (dev dependency) typescirpt: 2.6.2 (dev dependency) ts-node: 4.0.1 (dev dependency)

Reverted ts-node back to 3.30 solved the problem.

Interesting, thanks. I thought it may have been a duplicate of https://github.com/TypeStrong/ts-node/issues/481, but not if it’s on mac. Looks like these issues may be negative side effects of https://github.com/TypeStrong/ts-node/pull/419.

For anyone running into this, can you switch to using node -r ts-node/register? This avoids many of the process issues that were occurring and is likely the recommended way to use in the next release.

Hi, i have the same problem when using ts-node >= 4.x.x. When i save a file, node process isn’t killed and both dev port and inspector port remains used. If i downgrade to 3.x.x, it starts working again. I use this npm scripts to start in dev mode: "nodemon": "nodemon -e ts -w \"./src\" -x \"npm run debug\"", "debug": "ts-node --inspect ./src/index.ts",
