关于python:在VSCode中配置python3的调试环境

应用虚拟环境

• 设置虚拟环境
  应用 python 自带的 venv 创立一个虚拟环境

  python3 -m venv env

  执行下面的命令，会在我的项目根门路下生成一个 env 目录

• 激活虚拟环境

  source ./env/bin/activate

• 不应用虚拟环境

  deactivate

• 装置第三方库

  pip3 install -r requirements.txt

  设置我的项目的环境变量

• 配置环境变量文件 .env

  PYTHONUNBUFFERED=1
  ROBOT_DATA_PREFIX=/root
  PYTHONPATH=/root/IR_APP/app_server:/root/IR_APP/app_server/libs:/root/IR_APP/app_server/libs/common:/root/IR_APP/app_server/libs/controller_proto_pb2:/root/IR_APP/app_server/libs/controller_proto_pb2/protocal:/root/IR_APP/app_server/libs/controller_proto_pb2/message_type：$PYTHONPATH

• 在 workspace 的配置文件中增加配置setting.json

  {
    "files.watcherExclude": {
        "**/android/**": true,
        "**/doc/**": true,
        "**/references/**": true,
        "**/test/**": true,
        "**/tp_log/**": true,
        "**/.git/objects/**": true,
        "**/.git/subtree-cache/**": true,
        "**/node_modules/*/**": true
    },
    "python.linting.pylintEnabled": false,
    "python.linting.flake8Enabled": true,
    "python.linting.enabled": true,
    "python.formatting.provider": "autopep8",
    // 指定环境配置文件
    "python.envFile": "${workspaceFolder}/.vscode/.env",
    // 设置我的项目的环境变量
    "terminal.integrated.env.linux": {
        "LC_ALL": "zh_CN.UTF-8",
        "ROBOT_DATA_PREFIX": "/root"
    },
    // linux: 在 VSCode 中配置 Terminal
    "terminal.integrated.shellArgs.linux": ["-c", "source /root/IR_APP/app_server/env/bin/activate"],
    // window: 在 VSCode 中配置 Terminal
    "terminal.integrated.shellArgs.windows": ["/k", "C:\\Virtualenv\\py3env\\Scripts\\activate"]
  }

  设置 Debug 的配置文件

• 增加调试配置文件launch.json

    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
