错误TS2304：使用业力打字稿时找不到名称“地图”

Question

I try to run my first spec.ts file with karma-typescript and jasmine.

I already had a lot of different errors that I googled and "fixed" but I'm always getting just other problems.

• I added different entries in tsconfig.json->compilerOptions->"lib"
• tried to change the target
• tried out @types/core-js with version 0.9.46 and with 0.9.35
• updated node from 8.9.4 to 8.11.2
• tried to downgrade @types/node to some 8.x version

There is no problem to run the app. Just the test does not compile.

Do I need to configure the compiler of karma differently?

At the moment I just use the "minimal karma configuration " from 1 .

module.exports = function(config) {
config.set({
    frameworks: ["jasmine", "karma-typescript"],
    files: [
        "src/**/*.ts" // *.tsx for React Jsx
    ],
    preprocessors: {
        "**/*.ts": "karma-typescript" // *.tsx for React Jsx
    },
    reporters: ["progress", "karma-typescript"],
    browsers: ["Chrome"]
  });
};

The current error is

> ts-node node_modules/karma/bin/karma start ./karma.conf.js

My current tsconfig.json file

Thanks in advance for any tip!

I try to start the test with npm test .
I successfully run the app with npm run dev

Answer 1

I added the following lines to karma.config.js (inspired by this github issue )

karmaTypescriptConfig: {
    compilerOptions: {
        target: "ES2015",
        lib: ["es5", "es6", "es2015", "dom"]
    },
    tsconfig: "tsconfig.json"
},

This removes the compiler errors. I get runtime errors now, but that's another issue.
