如何在 ts-node 中使用项目依赖

Question

I am currently debugging a project that uses ts-node to run locally. Do I have to install ts-node globally for this?

I did install it globally, but now i am seeing typescript errors that stems from diverging typescript versions. I fixed it by setting it to the same version.

Is there a way to use my project dependencies in my CLI to run the project? Or do I HAVE to install things globally?

Answer 1

Since npm@5.2.0 , npm ships with the npx package, which lets you run commands from the node_modules/.bin directory in your current project. For example: npx ts-node -v .

If for whatever reason you have an older version of npm, you can install this package globally with npm install -g npx .

You can use npx <package-name> also for packages that aren't installed yet in your project (see its options ).

Alternatively, you can put the following into your package.json :

"scripts": {
    "start": "ts-node code/start.ts",
}

Commands in the scripts field also use the local version of a package.

By default, the node_modules folder has a .bin subdirectory. You can run the local version of ts-node while in the project directory.

Here's what you might type into your shell

cd /path/to/project
./node_modules/.bin/ts-node myFile.ts
