docker-compose報錯信息while parsing a block mapping in "./docker-compose.yml", line 3

while parsing a block mapping in "./docker-compose.yml", line 1

這個錯誤要注意是否輸入了全角的符號, 在xshell中不好查看的話最好現在editplus和notepad++這些工具中先編寫和檢查好,在copy進去

service 'restart' must be a mapping not a string.

這個錯誤是restart這個參數的縮進有問題.
