ML307R编译环境搭建

官方文档上对编译环境的搭建，轻描淡写，对于初学入门来说还是有点不好操作，这里也记录一下，方便别人避坑。
ML307R的sdk是基于Python使用scons编译的，这一点和ML307A不一样，ML307A不用安装别的软件，直接命令行编译就行。

官方文档的说明：

1. 先安装Python

我是直接在Windows的应用商城里安装的Python，比较省事，安装的3.24版本，文档要求3.7以上。

2.安装scons

安装过Python后，使用官方文档上的那个命令来安装scons：

pip install scons

C:\Windows\system32>pip install scons
Defaulting to user installation because normal site-packages is not writeable
Collecting scons
  Using cached SCons-4.8.0-py3-none-any.whl.metadata (9.1 kB)
Using cached SCons-4.8.0-py3-none-any.whl (4.1 MB)
Installing collected packages: scons
  WARNING: The scripts scons-configure-cache.exe, scons.exe and sconsign.exe are installed in 'C:\Users\wuwei\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.12_qbz5n2kfra8p0\LocalCache\local-packages\Python312\Scripts' which is not on PATH.
  Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
Successfully installed scons-4.8.0

安装成功后，上面有个提示，需要把scons的路径添加到环境变量里：

3.添加环境变量

win10或者win11，打开设置，在设置里搜索“环境变量”，如下图

如下截图把scons的路径添加到环境变量里：

4. 测试编译

配置好环境变量后，重新打开一个命令行，输入scons，出现如下提示说明安装成功：

编译测试：
