Command not found: ts-node-dev

Question

I am moving from nodemon to ts-node-dev but I am not able to run my index.ts file using ts-node-dev.

I did the following:

1. yarn add ts-node-dev --dev

2. In my package.json I have:

   "devDependencies": {
      ...
      "nodemon": "^1.19.2",
      "ts-node": "8.3.0",
      "ts-node-dev": "^1.0.0-pre.56",
      "typescript": "3.6.3"
   }
   

If I run ts-node-dev or ts-node-dev src/index.ts I get the error: command not found: ts-node-dev

What am I doing wrong? It seems to me that is correctly installed.

My scripts

   "scripts": {
      "start": "nodemon --exec ts-node src/index.ts",
      "dev": "ts-node-dev src/index.ts"
   }

You have 3 options here:

1. Run the command from actual path:

./node_modules/.bin/ts-node-dev src/index.ts

2. Use npx

npx ts-node-dev src/index.ts

3. Install the package globally (wouldn't recommend)

npm i -g ts-node-dev src/index.ts
ts-node-dev src/index.ts
