我使用的是Mac 10.13.2，我正在尝试按照说明获取谷歌助手设置。
我已经安装了google-assistant-sdk [samples]以及google-api-python-client以及google-auth-oauthlib [工具]我相信（当我尝试时，所有返回Requirement already up-to-date:的字符串安装/升级它们。
但是，只要我尝试这个命令：
python3 -m google-oauthlib-tool --client-secrets /Users/eric/Documents/18-01-15\ VoiceSearch/client_secret_xxSECRETNUMBERxx.apps.googleusercontent.com.json --scope https://www.googleapis.com/auth/assistant-sdk-prototype --save --headless
我收到以下错误：
/usr/local/bin/python3: No module named google-oauthlib-tool
我说错了吗？
哦，这就是我运行python3 -m pip show google-assistant-sdk
