在使用Sublime Text3编写Python3代码时，发现自带的Python运行环境无法实现Python内容的交互（如执行input()方法时输入没有交互），因此需要安装SublimeREPL来实现对Python3的支持。

一、为Sublime Text3安装Package Control

去 https://packagecontrol.io/installation 找到安装Package Control代码片段（此处可能需要科学上网），或者直接复制如下代码。


import urllib.request,os,hashlib; h = '6f4c264a24d933ce70df5dedcf1dcaee' + 'ebe013ee18cced0ef93d5f746d80ef60'; pf = 'Package Control.sublime-package'; ipp = sublime.installed_packages_path(); urllib.request.install_opener( urllib.request.build_opener( urllib.request.ProxyHandler()) ); by = urllib.request.urlopen( 'http://packagecontrol.io/' + pf.replace(' ', '%20')).read(); dh = hashlib.sha256(by).hexdigest(); print('Error validating download (got %s instead of %s), please try manual install' % (dh, h)) if dh != h else open(os.path.join( ipp, pf), 'wb' ).write(by)

打开Sublime Text控制台（快捷键：ctrl + ` 或者 view-->show console），粘贴代码并运行。

二、安装SublimeREPL

command + shift + p 打开命令提示框，输入Install Package（此处可能需要科学上网）。

命令提示框

然后输入SublimeREPL，点击安装。安装成功后可以看到Tools下面多了一个SublimeREPL。

三、配置Python3

Sublime Text --> Preferences --> Browse Packages，找到SublimeREPL中的config文件夹，在里面新建文件夹Python3，并将Python文件夹中的Default.sublime-commands 和 Main.sublime-menu拷贝到Python3中。

SublimeREPL中的config文件夹

分别将Default.sublime-commands 和 Main.sublime-menu内的文本替换为如下内容。
Default.sublime-commands：

[
    {
        "caption": "SublimeREPL: Python3",
        "command": "run_existing_window_command", "args":
        {
            "id": "repl_python3",
            "file": "config/Python3/Main.sublime-menu"
        }
    },
    {
        "caption": "SublimeREPL: Python - PDB current file",
        "command": "run_existing_window_command", "args":
        {
            "id": "repl_python_pdb",
            "file": "config/Python3/Main.sublime-menu"
        }
    },
    {
        "caption": "SublimeREPL: Python3 - RUN current file",
        "command": "run_existing_window_command", "args":
        {
            "id": "repl_python3_run",
            "file": "config/Python3/Main.sublime-menu"
        }
    },
    {
        "command": "python_virtualenv_repl",
        "caption": "SublimeREPL: Python - virtualenv"
    },
    {
        "caption": "SublimeREPL: Python - IPython",
        "command": "run_existing_window_command", "args":
        {
            "id": "repl_python_ipython",
            "file": "config/Python3/Main.sublime-menu"
        }
    }
]

Main.sublime-menu:

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

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

                     "args": {
                        "type": "subprocess",
                        "encoding": "utf8",
                        "autocomplete_server": true,
                        "cmd": {
                            "osx": ["python3", "-u", "${packages}/SublimeREPL/config/Python/ipy_repl.py"],
                            "linux": ["python3", "-u", "${packages}/SublimeREPL/config/Python/ipy_repl.py"],
                            "windows": ["python3", "-u", "${packages}/SublimeREPL/config/Python/ipy_repl.py"]
                        },
                        "cwd": "$file_path",
                        "syntax": "Packages/Python/Python.tmLanguage",
                        "external_id": "python3",

                        }
                    }
                    }
                ]}
            ]
        }]
    }
]

四、快捷键的设置

现在，如果需要使用Python3运行代码，可以去Tools-->SublimeREPL-->Python3 -->Python - RUN current file。

使用Python3运行代码

你还可以设置快捷键执行此动作：Sublime Text --> Preferences --> Key Bindings，添加如下代码（其中keys字段可以根据你的习惯自行指定）：

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

PS. 和Sublime Text3自带的解释器不同，使用SublimeREPL执行代码前需对代码进行保存。
