无法在Pepper上的Choregraphe中导入python模块

Question

我已经按照official Google tutorial通过SSH在胡椒机器人上安装了google speech API。

为了测试它，我创建了一个speechTest.py文件，我在其中导入如下接口：

from google.cloud import speech

这起作用了！到目前一切尚好。但是，当我想在Choregraphe中的Python框中执行相同的操作时，问题就出现了；当我收到错误消息时：

[ERROR] behavior.box :createPythonModule:0
_Behavior__lastUploadedChoregrapheBehaviorbehavior_11325017632:/GoogleSTT_7:
User class evaluation failed with the error:
<class 'pkg_resources.DistributionNotFound'>
google-cloud-speech

我尝试了解决方案raised in the community，但没有成功。当我从Python in Choregraphe框中打印sys.path时，我得到：

[WARN ] behavior.box :onLoad:15 _Behavior__lastUploadedChoregrapheBehaviorbehavior_1811402208:/GoogleSTT_7:

这将表明它应该找到Google包。我该如何解决这个问题？我不知道如何将Google Speech API导入到Choregraphe项目中。

编辑:当我在机器人上的本地Python文件中输出sys.path时，我得到这样的结果：
