我创建了一个裸ng new应用程序，该应用程序具有基于Karma的组件测试以及基于Protractor的e2e测试。当我像这样在AppVeyor中配置该存储库时：
version: 1.0.{build}
image: ubuntu
stack: node 10
cache:
- node_modules -> package.json
install:
- npm ci
- node --version
- npm --version
build: off
test_script:
- npm run lint
- npm test -- --progress=false
- npm run e2e
我会得到these errors：

The image contains Google Chrome（当前为74版）。我尝试添加
- sh: export CHROME_BIN=/usr/bin/google-chrome
到我的AppVeyor文件，但没有帮助。
我该怎么做才能在AppVeyor的Ubuntu映像上运行Angular组件和e2e测试？
