visual studio code 无法生成可执行文件（*.exe)，报错The prelaunchTask 'g++ builder' terminated with exit code -1.

1. 安装visual studio code
   下载很慢或者下载失败的，请转到我上传的文件。
2. 安装MinGW
   略
3. Path配置
   略
4. 安装c++ extension
   略

注意第一行type属性默认为cppbuild ,结果报错The prelaunchTask 'g++ builder'terminated with exit code -1.我把它改为了process，问题解决。
