Visual Studio 2017 Cordova App 项目系统遇到错误

Question

我有一个 HTML5/JavaScript Cordova 应用程序，当我启动它时出现此消息错误（有时只有一次，有时两次）。

.txt 文件中的文本如下：

我用的是Visual Studio2017专业版15.7.4

单击“确定”一两次后，一切恢复正常，如何删除此消息？

Answer 1

首先检查 Android Home、Java Home 和 npm 的所有参考资料。然后尝试在记事本中更改 .jsproj 文件，如

这个

<PropertyGroup>
<TypeScriptCompileOnSaveEnabled>false</TypeScriptCompileOnSaveEnabled></PropertyGroup>

至

<PropertyGroup>
<TypeScriptCompileBlocked>True</TypeScriptCompileBlocked>
<TypeScriptCompileOnSaveEnabled>false</TypeScriptCompileOnSaveEnabled</PropertyGroup>

如果没有成功，请尝试修复您的 vs 安装。
