Question

当我使用electron-builder包构建我的电子应用程序时，vs代码抛出错误：

除了关闭vs代码，我找不到其他解决方案。我不知道这是否是错误。

版本：

vs代码：1.33.1

操作系统：Windows_NT x64 10.0.17763

Answer 1

您可以使用https://lockhunter.com/中的“ Lock Hunter”来查看文件被哪些进程锁定。

有时可能是一些vs代码扩展。

通过使用“ Lock Hunter”，您可以通过勾选右上角的“更多详细信息”对勾来查看哪个vs代码扩展名锁定了文件。

对我来说，我发现它的“图像预览”扩展名锁定了文件。

Answer 2

从此chineese blog（重复on this other one）开始，我猜想，一种解决方案是使用VScode settings.json配置，从vscode文件查看器中排除 win-unpacked 子文件夹和文件：

{
  "files.watcherExclude": {
    "**/build/win-unpacked/**": true
  }
}

可以使用以下菜单通过vscode针对每个项目进行配置，不要忘记然后重新启动VScode：

/file/Preferences/Settings/Workspace/Text Editor/Files/Exclude/Add Pattern

，它将如上所述更新当前VScode项目目录的./.vscode/settings.json。 this github thread对此也有解释。

...检查asar文件的有效位置：就我而言，asar文件位于./dist/win-unpacked/resources/app.asar下因此，我将files.watcherExclude配置为

"**/dist/win-unpacked/**":true

文件被vs代码锁定
