Sublime Text下配置Python3开发环境

原来用的是Eclipse+PyDev写一些Python的小脚本，用上Sublime之后，就尝试在Sublime下面写python代码，发现Sublime的编译运行功能只是看起来很美，实际上连输入的功能都没有，于是安装了插件SublimeREPL，ctrl + shift + p 显示命令输入栏，输入SublimeREPL:Python RUN就能运行当前文件，而不输入Run就是进入Python 的命令行。经常用之后只要输入run就可以很方便地运行了，唯一的缺点是不能显示运行中的异常信息。另外，我还安装了All Autocomplete，Jedi 等等一堆Python语法自动补全插件 ，写代码从未如此简单！不过之后我悲伤地发现，SublimeREPL下面运行的是Python2.7.5，而我同时装了Python2.7.5和Python3.3.0，于是我就手动地添加了一个配置文件夹，让SublimeREPL能够运行Python3，文件夹新建在如下目录下

sublime安装位置\Data\Packages\SublimeREPL\config\

文件夹中包含 Default.sublime-commands 和 Main.sublime-menu 两个文件

Default.sublime-commands 内容如下

[
    {
        "caption": "SublimeREPL: Python3",
        "command": "run_existing_window_command", "args":
        {
            "id": "repl_python",
            "file": "config/Python/Main.sublime-menu"
        }
    },
    {
        "caption": "SublimeREPL: Python3 - RUN current file",
        "command": "run_existing_window_command", "args":
        {
            "id": "repl_python_run",
            "file": "config/Python3/Main.sublime-menu"
        }
    }
]

Main.sublime-menu文件内容如下

[
     {
        "id": "tools",
        "children":
        [{
            "caption": "SublimeREPL",

                    //     }
                    // },
                    {"command": "repl_open",

                     "id": "repl_python_run",

                        "type": "subprocess",
                        "encoding": "utf8",
                        "cmd": ["python3", "-u", "$file_basename"],
                        "cwd": "$file_path",
                        "syntax": "Packages/Python/Python.tmLanguage",
                        "external_id": "python",
                        "extend_env": {"PYTHONIOENCODING": "utf-8"}
                        }
                    }
                ]}
            ]
        }]
    }
]

保存之后运行Sublime Text 就能在Tools-->SublimeREPL下看到Python3的条目。 注意：要确认你可以从命令行中输入命令“Python3”可以运行Python3

试试看，运行Python3,，成功！
