2. Opening the file ~/Homestead/Homestead.yaml in PhpStorm, I noticed a red wavy underline. This might be because it was previously edited with EditPlus. As shown in Figure 2

3. I decided to reformat the file ~/Homestead/Homestead.yaml. As shown in Figure 3

4. After formatting, the red wavy underline disappeared. As shown in Figure 4

5. When starting vagrant again, the error no longer occurred.
