Angular (npm)在angular-devkit中的现有目录前面加上下划线，并给出"no directory“(ENOENT)错误

Question

编译我的Angular Electron应用程序会给出Error: ENOENT: no such file or directory, open 'node_modules/@angular-devkit/build-angular/src/angular-cli-files/_models/webpack-configs/browser.js'。该应用程序可以编译并运行。在运行npm install之后，问题出现了。

我的node-modules有包含browser.js的../angular-cli-files/models/..。奇怪的是，错误消息中有一个下划线，即_models。我完全不明白为什么会发生这样的事情。我已经尝试了几个SO answers Could not find module "@angular-devkit/build-angular"，Cannot find module 'webpack' - Angular和其他人的建议，但没有成功。我的搜索没有找到任何带有下划线的示例。

Answer 1

原来，postinstall.js和postinstall-web.js中路径'node_modules/@angular-devkit/build-angular/src/angular-cli-files/models/webpack-configs/browser.js'中的/models/部分不知何故更改为/_models/。我不知道这是怎么发生的，因为我从来没有打开过这些文件。

把它改回来就解决了问题。
