我使用 angular 7 cli 生成了一个全新的空项目。第一步是设置 Circle CI 来测试项目。

当我在我的电脑上运行它时，没问题：

npm run lint
npm run e2e

测试成功。

所以我把同样的东西放在我的circleci配置文件中：

# Javascript Node CircleCI 2.0 configuration file
#
# Check https://circleci.com/docs/2.0/language-javascript/ for more details
#
version: 2
jobs:
  build:
    docker:
      # specify the version you desire here
      - image: circleci/node:8.12.0

      # Specify service dependencies here if necessary
      # CircleCI maintains a library of pre-built images
      # documented at https://circleci.com/docs/2.0/circleci-images/
      # - image: circleci/mongo:3.4.4

    working_directory: ~/new_project

    steps:
      - checkout

      # Download and cache dependencies
      - restore_cache:
          keys:
            - v1-dependencies-{{ checksum "package.json" }}
            # fallback to using the latest cache if no exact match is found
            - v1-dependencies-

      - run: npm install

      - save_cache:
          paths:
            - node_modules
          key: v1-dependencies-{{ checksum "package.json" }}

      # run tests!
      - run: npm run lint
      - run: npm run e2e

当 CircleCi 运行它时，它失败了：

看来测试 angular 过程的 build 部分进展顺利，没有警告，没有错误，只有经典的 angular 构建日志。

版本： - node:8.12.0 - @angular/cli:7.2.0（也发生过，但也没有解决，在 7.1.x 中） - npm:6.4.1

知道如何解决它吗？在此先感谢您的帮助和想法！
