Sublime Text 3 配置python开发环境遇见的问题

安装的主要插件：

1. 
   
2. SublimeTmpl 提供了常用文件模板，新建文件时很有用。
3. Anaconda 是一个终极 Python 插件。它为 ST3 增添了多项 IDE 类似的功能,例如：
   

• Autocompletion 自动完成，该选项默认开启，同时提供多种配置选项
  
• Goto Definitions 能够在你的整个工程中查找并且显示任意一个变量，函数，或者类的定义。
  
• Find Usage 能够快速的查找某个变量，函数或者类在某个特定文件中的什么地方被使用了
  
• Code linting 代码静态分析功能，包括格式等，检查使用支持 pep8 标准的 PyLint 或者 PyFlakes
• SublimeLinter 会帮你查代码是否符合PEP8的要求。有问题有代码会出现白框，点击时底下的状态栏会提示出什么问题。
• Python PEP8 Autoformat 使用它进行符合PEP8要求的格式化
• SublimeREPL REPL就是read-evaluation-print-loop，（解释型语言编译运行的过程）。装了SublimeREPL插件后也支持了编辑器上直接的编译运行和交互

我配置过程中遇见的问题和解决方法：

Anaconda的问题

Anaconda默认配置和详细说明
Anaconda配置文件在
Sublime > Preferences > Package Settings > Anaconda > Settings – User：

  {  "pep8_ignore":
    [
        "E501",
    ],
    "complete_parameters": true,
    "anaconda_linting_behaviour": "save-only",// always
    "anaconda_gutter_theme": "hard",
    "anaconda_linter_show_errors_on_save": true,
    "python_interpreter": "/Library/Frameworks/Python.framework/Versions/3.5/bin/python3",
    "anaconda_linting": true,
}

a. 代码linting太严

例如：我逗号”,”后面没加空格，它就会用白框框这么提示我代码不规范

它管的太严，所以我们可以在pep8_ignore里填入要忽视的错误码，所有错误码

或者我们可以关闭anaconda的代码检查”anaconda_linting”: false,
使用Python PEP8 Autoformat 格式化代码

b. anaconda 不能自动补全第三方库

原因是：Anaconda使用的Python版本不是我们系统安装的Python
可通过一下进行配置，使anaconda使用我们电脑上的Python,那样安装在我们电脑上python的第三方库也就会自动导入了
官方配置传送门
如上，关键在”python_interpreter”中写入本机安装的python的完整路径，例如：/Library/Frameworks/Python.framework/Versions/3.5/bin/python3,

SublimeREPL的问题

使用SublimeREPL进行编译运行时，设置SublimeREPL的python为我们机器上的python，不然会出现和上面Anaconda的b一样的问题
解决方法：从电脑目录里找到SublimeREPL/config/Python/Main.sublime-menu文件
例如：Packages/User/SublimeREPL/config/Python/Main.sublime-menu
在Main.sublime-menu文件里配置如下：
我最常用的是用python或者run current file,所以找到这两个，在他们的cmd下填入要关联的本机的python所在的完整目录

{"command": "repl_open",
                     "caption": "Python",
                     "id": "repl_python",

                        }
                    },

                        "syntax": "Packages/Python/Python.tmLanguage",

                        "extend_env": {"PYTHONIOENCODING": "utf-8"}
                        }
                    },

that’s all ! thank you !
