Angular 在 Travis 上运行测试失败，错误 "Found 1 load error"

Question

为什么我的 travis conf 无法执行 Angular 测试？

.travis.yml

language: node_js
node_js:
  - "16"

addons:
  chrome: stable

cache:
  directories:
    - ./node_modules
    - ./.angular

install:
  - npm install

script:
  - npm run test -- --code-coverage --no-watch --no-progress --browsers=ChromeHeadlessCI

after_script:
  - cat ./coverage/*/lcov.info | ./node_modules/coveralls/bin/coveralls.js

错误

我假设您已将项目升级到 Angular13。我将 karma-coverage-istanbul-reporter 替换为 karma-coverage 并且工作正常。

在 karma.conf.js 中，您应该将 coverageIstanbulReporter 替换为 coverageReporter，如下所示

coverageReporter: {
  dir: require('path').join(__dirname, './coverage/<your-project-name>'),
  subdir: '.',
  reports: [
    { type: 'html' },
    { type: 'lcovonly' },
    { type: 'text-summary' }
  ]
},
