【问题描述】：
我正在关注 this guide 并使用 addressbook.proto 的确切示例。
同时发布编译器生成的addressbook_pb2.py 文件的内容。 当我运行以下简单程序时，出现错误提示，找不到 google.protobuf，任何想法如何解决这个问题？谢谢。
顺便说一句，在 Mac OSX 上使用 Python 2.7。
from addressbook_pb2 import Person
p = Person()
p.email = "abc"
print p.email
这里是自动生成的文件addressbook_pb2.py，

试过pip install protobuf，遇到如下错误，

【问题讨论】：
-
您是否将其中一个文件命名为“google.py”？
-
Lin Ma，你有两个独立的 python 安装正在运行。
/Users/foo/anaconda/上的一个（这是从您的代码中调用的那个）和 /Users/foo/miniconda2/` 中的一个（这是您从终端键入pip时调用的那个。考虑找到scripts或/Users/foo/anaconda中的bin目录（以包含pip的为准）并从该目录中运行pip install ...。这应该将protobuf 包安装在正确的位置，以便您在当前代码设置中使用它。跨度> -
@jedwards，很好地抓住并投票。想知道我应该使用
pip install google还是pip install protobuf？ -
@jedwards，尝试使用完整路径执行
pip，请参阅编辑 5 部分的更新。似乎据说protobuf已经在那里了。然后我尝试从 PyCharm 执行，遇到了同样的问题，No module named google.protobuf，如果您有任何进一步的想法，那就太好了。 :) -
尝试
cd /Users/foo/anaconda/bin然后./pip install protobuf-- 或 --cd /Users/foo/anaconda/bin然后./python -m pip install protobuf
