我尝试在 ubuntu16.04 上设置 andorid-gts。python版本是2.7.16。我已经安装了以下软件包：
pip install future
pip install protobuf
pip install auth
pip install compiler
pip install virtualenv
pip install PyPi
pip install google-cloud-storage
pip install oauth2client
但是当我尝试从控制台运行 gts 命令时，总是出现以下错误：
android Google Mobile Services (GMS) Test Suite 7.0_r3 (6045416)
Use "help" or "help all" to get more information on running commands.

我想这可能是由超时日志引起的：
