jest-preset-angular: ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './dist/ts-jest-transformer' is not defined by "exports".

Node 12.20.0+ or 14.13.0+, see https://nodejs.org/api/packages.html#packages_subpath_patterns

I will bring this up to ts-jest, seem like node at 12.20 is required.

Strange that my work uses Node 12.14 can still run, probably cache on CI server.

Had the same issue - turned out to be node version problem - had run with Node v14.6. Hope that helps somebody.

Edit: switching to v14.16.x fixed it.

I have the same problem. After upgrading to the newest version, I get Package subpath './dist/ts-jest-transformer' is not defined by "exports" in C:\Users\name\project\node_modules\ts-jest\package.json.

I’m using Windows & Angular 11.2.13, no nrwl.

As a temporary fix, I can change the content of node_modules\ts-jest\package.json from:

  "exports": {
    ".": "./dist/index.js",
    "./dist/*": "./dist/*.js",
    "./jest-preset": "./jest-preset.js",
    "./presets": "./presets/index.js",
    "./utils": "./utils/index.js",
    "./package.json": "./package.json"
  }

to

  "exports": {
    ".": "./dist/index.js",
    "./dist/*": "./dist/*.js",
    "./jest-preset": "./jest-preset.js",
    "./presets": "./presets/index.js",
    "./utils": "./utils/index.js",
    "./package.json": "./package.json",
    "./dist/ts-jest-transformer": "./dist/ts-jest-transformer.js",
    "./dist/compiler/ts-compiler": "./dist/compiler/ts-compiler.js"
  },

Then it works. So it seems like the wildcard export is not correctly resolved. But I don’t know why the example project works fine.
