2. View the file ~/homestead/homestead.yaml in phpstorm, and find a red wavy line prompt. The reason may be that it has been edited with EditPlus before. as shown in Figure 2

3. Decide to reformat the file ~/homestead/homestead.yaml. as shown in Figure 3

4. After formatting, there is no longer a red wavy line prompt. as shown in Figure 4

5. When vagrant is started again, an error will not be reported.
