已安装：

 pip install google-python-cloud-debugger
Requirement already satisfied (use --upgrade to upgrade): google-python-cloud-debugger in /usr/local/lib/python2.7/dist-packages
Requirement already satisfied (use --upgrade to upgrade): google-api-python-client in /usr/local/lib/python2.7/dist-packages (from google-python-cloud-debugger)
Requirement already satisfied (use --upgrade to upgrade): six<2,>=1.6.1 in /usr/local/lib/python2.7/dist-packages (from google-api-python-client->google-python-cloud-debugger)
Requirement already satisfied (use --upgrade to upgrade): httplib2<1,>=0.8 in /usr/local/lib/python2.7/dist-packages (from google-api-python-client->google-python-cloud-debugger)
Requirement already satisfied (use --upgrade to upgrade): oauth2client in /usr/local/lib/python2.7/dist-packages (from google-api-python-client->google-python-cloud-debugger)
Requirement already satisfied (use --upgrade to upgrade): uritemplate<1,>=0.6 in /usr/local/lib/python2.7/dist-packages (from google-api-python-client->google-python-cloud-debugger)
Requirement already satisfied (use --upgrade to upgrade): pyasn1>=0.1.7 in /usr/local/lib/python2.7/dist-packages (from oauth2client->google-api-python-client->google-python-cloud-debugger)
Requirement already satisfied (use --upgrade to upgrade): pyasn1-modules>=0.0.5 in /usr/local/lib/python2.7/dist-packages (from oauth2client->google-api-python-client->google-python-cloud-debugger)
Requirement already satisfied (use --upgrade to upgrade): rsa>=3.1.4 in /usr/local/lib/python2.7/dist-packages (from oauth2client->google-api-python-client->google-python-cloud-debugger)
Requirement already satisfied (use --upgrade to upgrade): simplejson>=2.5.0 in /usr/local/lib/python2.7/dist-packages (from uritemplate<1,>=0.6->google-api-python-client->google-python-cloud-debugger)

但是在尝试导入时，我得到了ImportError: No module named uritemplate。堆栈跟踪是： googleapiclient/discovery.py", line 53, in <module>

事情是uritemplate已安装：

pip install uritemplate
Requirement already satisfied (use --upgrade to upgrade): uritemplate in /usr/local/lib/python2.7/dist-packages
Requirement already satisfied (use --upgrade to upgrade): simplejson>=2.5.0 in /usr/local/lib/python2.7/dist-packages (from uritemplate)

直接导入uritemplate 也不起作用..

【解决方案1】：

我也有同样的问题。 uritemplate 已下载到我的文件系统。解决这个问题后，oauth2client 也是如此我不得不更新。从https://github.com/google/oauth2client下载

所以我将更新版本下载到我的项目中并添加了它的路径。

【解决方案2】：

你是在导入云调试器时调用python2.7还是python3，还是直接uritemplate？

$ python2.7 
>>> import uritemplate
>>> 
$ python3 
>>> import uritemplate
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named uritemplate

请注意，云调试器（和 uritemplate）适用于 python 2.7。
