我无所适从时遇到了这个错误

Answer 1

我也有这个问题。我没有错误地缩进，而是不小心在Homestead.yaml文件中添加了另一个破折号（-）。

例如，这是不正确的：

- map: testing.khc.my
- to: /home/vagrant/code/testing/public

在正确的一个是这样的：

- map: testing.khc.my
  to: /home/vagrant/code/testing/public

希望这对以后的所有人有所帮助。

Answer 2

我也遇到了这个错误，这真的很痛苦。问题的根源是 Homestead.yaml 文件中的错误缩进。检查您使用的是空格还是制表符。
