业力打字稿找不到模块“ ready-stream / duplex.js”

我在这里找到的最接近的东西是karma-typescript cannot find module,但是那是指因果报应类型找不到源文件而不是依赖项的问题。它的解决方案还是行不通的。

我正在尝试使用Karma,Mocha和Chai为TypeScript项目设置单元测试。我决定在npm中使用karma-typescript包来设置测试,因此不必先编译为Javascript。当我运行“ karma start karma.conf.js”时,它将运行一段时间,然后返回:

02 03 2019 14:08:28.791:DEBUG [coverage.karma-typescript]: Initializing
02 03 2019 14:08:28.799:DEBUG [compiler.karma-typescript]: Setting up deferred project compilation
02 03 2019 14:08:28.800:DEBUG [coverage.karma-typescript]: Configuring coverage preprocessor
02 03 2019 14:08:28.805:ERROR [karma-server]: Server start failed on port 9876: Error: Cannot find module 'readable-stream/duplex.js'
npm ERR! Test failed.  See above for more details.

我尝试过手动添加可读流,即使可读流在karma-typescript的package.json中,但似乎没有什么不同。我已经这样设置了karma.conf.js:

const puppeteer = require('puppeteer');
process.env.CHROME_BIN = puppeteer.executablePath();

module.exports = function(config) {
config.set({

basePath: '',

frameworks: ['mocha', 'chai', 'karma-typescript'],

karmaTypescriptConfig: {
  compilerOptions: {
    module: "commonjs"
  },
  tsconfig: "./src/ts/tsconfig.json"
},

files: [
  'src/**/*.ts'
],

exclude: [
],

preprocessors: {
  "**/*.ts": ["karma-typescript"]
},

reporters: ['progress', 'karma-typescript'],

port: 9876,

colors: true,

// possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
logLevel: config.LOG_DEBUG,

autoWatch: false,

browsers: ['ChromeHeadless'],

singleRun: true,

concurrency: Infinity
})
}

我的tsconfig.json看起来像这样,并与所有.ts源文件(src / ts /)存储在同一文件夹中:

{
   "compilerOptions": {
   "target": "es2018",
   "outDir": "../js",
   "rootDir": "./",
   "strict": true,
   "moduleResolution": "node",
   "esModuleInterop": true
   }
}
