推荐答案

在大多数情况下，如果目录没有足够的权限，ng serve或ng build --watch都不起作用.

Most of the times in Linux, ng serve or ng build --watch doesn't work if the directory doesn't have sufficient permissions.

解决方案是提供必要的权限或使用sudo.

The solution is either to provide the necessary permissions or to use sudo instead.

更新

watch标志是多余的，因为它是默认选项.感谢@Zaphoid指出了错误.

watch flag in ng serve is actually redundant as it is the default option. Credit to @Zaphoid for pointing out the mistake.
