那么，我们开始吧

Step 1. 首先我们需要下载一个.py的文件，是用来解决行号的

下载地址：svwh.dl.sourceforge.net/project/sourcetrac/tmp/IDLE/idlexlib/extensions/LineNumbers.py

这个网址需要科学上网，所以我把.py的内容直接粘贴到这里了，

不方便的童鞋可以建一个名字为“LineNumbers.py”的文件，其内容如下

Step 2. 接着，我们要找到安装目录下的Lib\idlelib目录，复制LineNumber到这个目录

这里有个问题，就是（至少对我来说，在MacOS下找安装目录不是很方便），建议的方法是，直接在Finder（Finder的Macintosh HD）下搜索idlelib,理论上会搜到两个,因为Mac会自带一个Python2的环境，找咱们下的Python3环境，我电脑上的路径长这样：

这个就是对应（目前大多数Windows系统下的所在idlelib目录）

然后就是复制LineNumber到这个目录就可以

 

Step 3. 再接着，打开LineNumber.py文件，把文件中的下述这三行代码

from idlelib.configHandler import idleConf from idlelib.Delegator import Delegator from idlelib.Percolator import Percolator

改为：

from idlelib.config import idleConf from idlelib.delegator import Delegator from idlelib.percolator import Percolator

改完记得保存下

 

Step 4. 之后，开始配置extensions.def：

还是在刚刚的那个idlelib目录下，找到config-extensions.def文件，往config-extensions.def文件配置如下数据：

[LineNumbers] enable=True #开启扩展 enable_editor=True #开启idle编辑器支持 enable_shell=True #开启idle shell支持 visible=True #扩展可见

我添加的位置不知道规不规范，但是亲测可行

我加在了这里：如图示，第20-28行的位置

至此，配置工作结束。

重启后，在Options选项中有Show Line Numbers，点击勾选就可以拥有行号了

（但是有两个，下面的那个不好使，不知道为什么，但是上面那个好使就可以了啊-- ）
