python-2.7 - 如何在 circle.yml 中运行 flake8

Question

构建circle ci服务器时出现以下错误。

bash: line 1: flake8: command not found flake8 app/ returned exit code 127

Answer 1

您可以在您的 requirements.txt 中添加 flake8 并将 flake8 命令添加为您的 circleci 配置中的步骤之一。首先，您可以使用 circleci 样板代码，因此最终结果将是这样的。

# Python CircleCI 2.0 configuration file
#
# Check https://circleci.com/docs/2.0/language-python/ for more details
#
version: 2
jobs:
  build:
    docker:
      # specify the version you desire here
      # use `-browsers` prefix for selenium tests, e.g. `3.6.1-browsers`
      - image: circleci/python:3.5.3

      # 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/postgres:9.4
    working_directory: ~/repo
    steps:
      - checkout
      # Download and cache dependencies
      - restore_cache:
          keys:
          - v1-dependencies-{{ checksum "requirements.txt" }}
          # fallback to using the latest cache if no exact match is found
          - v1-dependencies-
      - run:
          name: install dependencies
          command: |
            python3 -m venv venv
            . venv/bin/activate
            pip install -r requirements.txt
      - save_cache:
          paths:
            - ./venv
          key: v1-dependencies-{{ checksum "requirements.txt" }}

      # run tests!
      - run:
          name: run linting and metrics
          command: |
            . venv/bin/activate
            flake8 ./ tests --output-file test-reports
      - store_artifacts:
          path: test-reports
          destination: test-reports

Answer 2

1. 确保flake8包含在requirements.txt文件中。

2. 在您的文件中包含以下内容circle.yml：

   test:
     override:
       - flake8 ./
   

您可以随意配置此 flake8 命令，例如flake8 ./ --max-line-length=100.
