为什么 ts-node 不编译打字稿文件？

Question

Why is ts-node not compiling and executing typescript file? It is used in terminal like "ts-node scriptfile" It just returns a blank line. What is wrong? Thanks for the help.

Answer 1

There is another simple way of running .ts files

First of all you have to install typescript

npm i -g typescript

then run your .ts file with this command

tsc fileName.ts | node fileName.js

Note: the command above will generate an extra file named fileName.js

and finally make sure that you are using console.log() to return anything

Answer 2

ts-node is a typescript executor, not a compiler. If you run npx ts-node script.ts it will execute as typescript, without compiling.

To generate a compiled js file, try tsc script.ts .
