使用env 环境 scons -j8 编译 PersimM3_SDK_V1.5.0_20210226\project\firmware 的软件包 （此软件包为开发板厂家 睿赛德科技 网盘上下载的 ） 出现 错误，错误信息如下：

朋友们有知道什么原因的么？
在最上面有这样的信息：
scons: warning: No version of Visual Studio compiler found - C/C++ compilers most likely not set correctlyFile "E:\Persimmon_PROJECT\PersimM3_SDK_V1.5.0_20210226\project\firmware\SConstruct", line 22, in <module>
