Question

我试图使用茉莉花编写Angular服务的单元测试，首先在快速搜索后将“ angularcli”的每个实例都更改为“ @angularcli”，但无法找到模块“ angularcli / plugins / karma”，但仍然存在运行“ ng测试”的问题。这是错误：

20 07 2018 17:07:57.919:ERROR [config]: Error in config file!
 { Error: Cannot find module '@angular-cli/plugins/karma'

我已更新karma.conf.js以使其与@ angular-cli静止节点一起找不到模块

这是我的Karma.conf.js

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular-cli'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),      
      require('@angular-cli/plugins/karma')
    ],
    client: {
      clearContext: false
    },
    files: [
      { pattern: './src/test.ts', watched: false }
    ],
    preprocessors: {
      './src/test.ts': ['@angular-cli']
    },
    mime: {
      'text/x-typescript': ['ts','tsx']
    },
    coverageIstanbulReporter: {
      reports: [ 'html', 'lcovonly' ],
      fixWebpackSourcePaths: true
    },
    coverage: {
      reports: {
        html: 'coverage',
        lcovonly: './coverage/coverage.lcov'
      }
    },
    angularCli: {
      environment: 'dev'
    },
    reporters: config.angularCli && config.angularCli.codeCoverage
              ? ['progress', 'coverage-istanbul']
              : ['progress', 'kjhtml'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['Chrome'],
    singleRun: false
  });
};

这是来自package.json的开发依赖项

        "@angular/cli": "^1.2.5",

Answer 1

您需要在所有情况下将@angular-cli更改为@angular/cli。

希望这会有所帮助！

错误：找不到模块“ @ angular-cli / plugins / karma”
