我无法为Android安装depot_tools。
我遵循this website上列出的说明，并且在空目录中运行fetch android时遇到以下问题：
Running: gclient root
Running: gclient config --spec 'solutions = [
{
"url": "https://chromium.googlesource.com/chromium/src.git",
"managed": False,
"name": "src",
"custom_deps": {},
},
]
target_os = ["android"]
'
Running: gclient sync
