Matlab2022a无法识别vs2019编译器，未检测到支持的编译器，错误使用Mex -setup error cannot find support compiler-Toy模板网

这篇具有很好参考价值的文章主要介绍了Matlab2022a无法识别vs2019编译器，未检测到支持的编译器，错误使用Mex -setup error cannot find support compiler。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

1、确定一下您的问题：错误使用Mex
Matlab2022a无法识别vs2019编译器，未检测到支持的编译器，错误使用Mex -setup error cannot find support compiler
2、再执行以下命令：

如果您的结果跟我一样，那么可以继续看，如果不一样，就可能不是同一个问题。
下面直接说解决方案：
3、打开powershell，执行下面命令
install-module -scope currentuser MSI

install-module -scope currentuser MSI

按照提示输入Y

4、继续执行命令
get-msirelatedproductinfo ‘{1571205C-BAD1-4237-BFE6-B77E622C51DB}’

get-msirelatedproductinfo '{1571205C-BAD1-4237-BFE6-B77E622C51DB}'

很有可能该命令会出错
Matlab2022a无法识别vs2019编译器，未检测到支持的编译器，错误使用Mex -setup error cannot find support compiler 该错误是因为禁用了脚本执行的权限，需要再执行允许执行脚本权限即可

5、出现上面错误时执行命令，否则跳过
set-ExecutionPolicy RemoteSigned

set-ExecutionPolicy RemoteSigned

这时，再执行上面的命令就可以正常执行了。

6、继续执行命令
get-msirelatedproductinfo ‘{1571205C-BAD1-4237-BFE6-B77E622C51DB}’ | repair-msiproduct

get-msirelatedproductinfo '{1571205C-BAD1-4237-BFE6-B77E622C51DB}' | repair-msiproduct

执行该命令很有可能还会出错
Matlab2022a无法识别vs2019编译器，未检测到支持的编译器，错误使用Mex -setup error cannot find support compiler
该错误是因为set configuration出错，
解决方案：下载一个最新的Microsoft.VisualStudio.Setup.Configuration.msi安装就可以了。
或者从vs2019安装文件中搜索“Microsoft.VisualStudio.Setup.Configuration.msi”，并安装就好了。
安装完后，再执行一次出错的命令就会正常了。

7、至此，问题已经解决，测试命令
vswhere.exe
如果输出仍然是第2步的结果，则说明未解决，如果输出如下，则ok

因为该问题，我已经测试了很多种方法，网上基本上就是修改注册表，清理注册表，重装matlab，重装vs都试过了，全都无效，就差重装系统了。也不是安装先后的问题，差点就要放弃了。也测试了TotalUninstaller.zip工具卸载，无效。该问题困扰多天，希望能够帮助后来人不要受到该问题困扰。

====================================================================
下面是第二种解决方案，可以参考
其实修改注册表的办法不是没有效，只是需要根据xml文件内容来更改，如果您的xml文件与我的一样，那么可以尝试通过注册表解决

或者将那两个xml文件替换为上述内容，并修改注册表
a、输入regedit
b、找到计算机\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\Sxs\VS7
新建或修改
Matlab2022a无法识别vs2019编译器，未检测到支持的编译器，错误使用Mex -setup error cannot find support compiler

以上两种方法应该都能解决matlab无法识别vs编译器的问题。明明安装了vs2019却说找不到支持的编译器。
这之后可以执行mex -setup命令试试
