如何生成 tsconfig.json 文件？

Question

How can I generate a tsconfig.json via the command line? I tried command tsc init , but this doesn't work.

Answer 1

It is supported since the release of TypeScript 1.6.

The correct command is --init not init :

$ tsc --init

Try to run in your console the following to check the version:

$ tsc -v

If the version is older than 1.6 you will need to update:

$ npm install -g typescript

Remember that you need to install node.js to use npm.

Answer 2

For those who have TypeScript installed as a local package (and possibly as a dev dependency) via:

$ npm install typescript --save-dev

...and who have added tsc script to package.json:

"scripts": {
   ...
   "tsc": "tsc"
},

You can call tsc --init via npm :

$ npm run tsc -- --init 

Answer 3

If you don't want to install Typescript globally (which makes sense to me, so you don't need to update it constantly), you can use npx:

npx -p typescript tsc --init

The key point is using the -p flag to inform npx that the tsc binary belongs to the typescript package

这对我有用：

tsc --init

Answer 5

Setup a ts project as following steps:

• install typescript yarn global add typescript
• create a package.json : run yarn init or setting defaults yarn init -yp
• create a tsconfig.json : run tsc --init
• (*optional) add tslint.json

The project structure seems like:

│  package.json
│  tsconfig.json
│  tslint.json
│  yarn.lock
│
├─dist
│      index.js
│
└─src
       index.ts

Answer 6

You need to have typescript library installed and then you can use

npx tsc --init 

If the response is error TS5023: Unknown compiler option 'init'. that means the library is not installed

yarn add --dev typescript

and run npx command again

Answer 7

install TypeScript :

npm install typescript

add tsc script to package.json:

"scripts": {
  "tsc": "tsc"
 },

run this:

npx tsc --init

Answer 8

npm install -g typescript 
tsc --init 

Then sometimes after you globally updated typescript you probably again need to add it to your current project.

npm install typecsript ts-node nodemon - if you need it.

$ npm run tsc -- --init
This worked for the below package.json

  "devDependencies": {

    "jasmine": "^3.6.3",
    "protractor": "^7.0.0",
    "typescript": "^4.1.3"
  },

Answer 11

I recommend to uninstall typescript first with the command:

npm uninstall -g typescript

then use the chocolatey package in order to run:

choco install typescript

in PowerShell.

Answer 12

From 2ality . You can add a function in your .zshrc or .bashrc to shortcut to the local bin path.

# in .zshrc:
function npm-do { (PATH=$(npm bin):$PATH; eval $@;) }

# working inside your directory:
npm-do tsc --init

Answer 13

the Normal way to generate the tsconfig file is to create a file with a name tsconfig.json then open {} ,inside this {} hit

ctrl + spacebar ( Windows)

cmd + spacebar (mac)

then choose compilationOptions then choose what options you need

---

For auto-generation (tsconfig.json) using VSCode terminal or any cmd on the same directory you wanna create :

tsc --init

Answer 14

In case someone comes here looking for what I was looking for, the tsconfig.json file with more options

npx tsconfig.json 

was not working for me so instead:

npx tsconfig.json.cmd

gave me the tsconfig.json file I was looking for which offers more options

this worked for me on Windows
