Cannot find module 'ts-transformer-keys'. Did you mean to set the 'moduleResolution' option to 'node', or to add aliases to the 'paths' option?

Question

I want to use ts-transformer-keys in my typescript project "typescript": "^4.5.5". So I added this dependency to the typescript package.json:

"ts-transformer-keys": "^0.4.3",

and added this to tsconfig.json like this:

"plugins": [
      { "transform": "ts-transformer-keys/transformer" }
] 

but when I import the ts-transformer-keys in the current project:

import { keys } from 'ts-transformer-keys';

shows error:

Cannot find module 'ts-transformer-keys'. Did you mean to set the 'moduleResolution' option to 'node', or to add aliases to the 'paths' option?ts(2792)

Why did this happen? What should I do to fix this problem? I have already run the yarn command. The node version is 16.13.2.

this error message tell how to fix this problem, the typescript default module resolution is classic, this would not search from node_modules. That why tell you did not found the module that in the node_modules folder. more info you can read from here: https://www.typescriptlang.org/docs/handbook/module-resolution.html, so fix your problem, try add "moduleResolution": "node" in your "tsconfig.json" (or "jsconfig.json") file:

"compilerOptions": {
    //...
    "moduleResolution": "node",
}
