devTools日志记录

[Vue warn]: You are using the runtime-only build of Vue where the template compiler is not available. Either pre-compile the templates into render functions, or use the compiler-included build.

其他：

INFO  Not launching electron as debug argument was passed. You must launch electron through your debugger.
 INFO  If you are using Spectron, make sure to set the IS_TEST env variable to true.
 INFO  Learn more about debugging the main process at https://nklayman.github.io/vue-cli-plugin-electron-builder/guide/testingAndDebugging.html#debugging.

这些异常都是构建配置不合理导致的，后来重新搭建工程后就没异常了
