CircleCI 2.0，apt-get 因“权限被拒绝”而失败

Question

我正在设置 CircleCI 2.0 配置，我需要包含 ubuntu 包“pdf2htmlex”，但出现以下错误：

apt-get update && apt-get install -y pdf2htmlex
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)
E: Unable to lock directory /var/lib/apt/lists/
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
Exited with code 100

这是.circle/config.yml的相关部分：

version: 2
jobs:
  build:
    docker:
      # specify the version you desire here
      - image: circleci/node:7.10
      - image: circleci/postgres:9.6.2

      # 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: ~/repo

    steps:
      - checkout
      - run:
          name: Install System Dependencies
          command: apt-get update && apt-get install -y pdf2htmlex      
      - run:
          name: save SHA to a file
          command: echo $CIRCLE_SHA1 > .circle-sha
      - restore_cache:
          key: dependency-cache-{{ checksum "package.json" }}
      - run:
          name: Install dependencies via npm
          command: npm install
      - run:
          name: Run tests
          command: npm run test
      - run: scripts/build.sh
      - save_cache:
          key: dependency-cache-{{ checksum "package.json" }}
          paths:
            - node_modules
      - save_cache:
          key: v1-repo-{{ checksum ".circle-sha" }}
          paths:
            - ~/repo

任何人都可以提出解决方法，因为这会导致我们的一些集成测试失败？

您应该可以将sudo 添加到apt-get 安装行：

version: 2
jobs:
  build:
    docker:
      # specify the version you desire here
      - image: circleci/node:7.10
      - image: circleci/postgres:9.6.2

      # 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: ~/repo

    steps:
      - checkout
      - run:
          name: Install System Dependencies
          command: sudo apt-get update && sudo apt-get install -y pdf2htmlex      
      - run:
          name: save SHA to a file
          command: echo $CIRCLE_SHA1 > .circle-sha
      - restore_cache:
          key: dependency-cache-{{ checksum "package.json" }}
      - run:
          name: Install dependencies via npm
          command: npm install
      - run:
          name: Run tests
          command: npm run test
      - run: scripts/build.sh
      - save_cache:
          key: dependency-cache-{{ checksum "package.json" }}
          paths:
            - node_modules
      - save_cache:
          key: v1-repo-{{ checksum ".circle-sha" }}
          paths:
            - ~/repo
