Sublime Text 3 配置python开发环境遇见的问题

安装的主要插件：

SublimeTmpl 提供了常用文件模板，新建文件时很有用。

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

E101 - Reindent all lines.
E111 - Reindent all lines.
E121 - Fix indentation to be a multiple of four.
E122 - Add absent indentation for hanging indentation.

W391 - Remove trailing blank lines.
E26 - Format block comments.
W6 - Fix various deprecated code (via lib2to3).
W602 - Fix deprecated form of raising exception.

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",
"mnemonic": "P",
"args": {
"type": "subprocess",
"encoding": "utf8",
"cmd": ["/Library/Frameworks/Python.framework/Versions/3.5/bin/python3", "-i", "-u"],
"cwd": "$file_path",
"syntax": "Packages/Python/Python.tmLanguage",
"external_id": "python",
"extend_env": {"PYTHONIOENCODING": "utf-8"}
}
},

{"command": "repl_open",
"caption": "Python - RUN current file",
"id": "repl_python_run",
"mnemonic": "R",
"args": {
"type": "subprocess",
"encoding": "utf8",
"cmd": ["/Library/Frameworks/Python.framework/Versions/3.5/bin/python3", "-u", "$file_basename"],
"cwd": "$file_path",
"syntax": "Packages/Python/Python.tmLanguage",
"external_id": "python",
"extend_env": {"PYTHONIOENCODING": "utf-8"}
}
},

that’s all ! thank you !
