ng build --watch删除dist内目录致about-us库链接失败求助

背景 #

我的应用依赖两个Angular库：contact-us和about-us。contact-us已成功链接并正常使用，但用相同流程处理about-us时出现了一系列异常。

about-us链接操作步骤 #

cd libraries/about-us/
npm run build
cd /dist/about-us
npm link
ng build --watch

执行ng build --watch后的错误信息 #

注：以下错误标注3个关键点

异常现象分析 #

执行命令后dist目录被清空，项目文件夹被删除，这是触发ENOENT错误的直接原因。

尝试调整后的问题 #

将ng build --watch移至about-us根目录执行，构建无错误，但在应用目录执行以下命令时：

npm link about-us
ionic cap build android

应用无法识别该库，报错：

cannot find module 'about-us' or its corresponding type declarations.
29     loadChildren: () => import('about-us').then(m => m.AboutusModule)
                                  ~~~~~~~~~~~~~~~~
[ERROR] An error occurred while running subprocess ng.
        ng run app:build exited with exit code 1.

同时发现应用node_modules目录中，about-us的链接与contact-us的链接存在差异。

问题诉求 #

需要明确ng build --watch异常的根本原因，以及解决库链接后应用无法识别的问题。

环境信息 #

• Node版本：nvm 14.20
• Angular CLI版本：14.0.1
