使用 ts-node 转译 mocha 测试时，我找不到模块“tsconfig/register”

Question

I have run both npm i ts-node and npm i ts-node --save-dev with no changes. ts-node works fine when I run it from the command line, but for some reason I cannot run mocha tests through test explorer. I get the error below:

error:

Turns out none of the package.json config options were working for me. I wound up implementing a .mocharc.json on the same level as my package.json which worked perfectly.

Example from this github repo (with more examples) copied here for posterity.

{
  "extension": ["ts"],
  "spec": "src/**/*.spec.ts",
  "require": "ts-node/register"
}
