Python &引用；ImportError：没有名为google.protobuf的模块；但是它'；它肯定安装好了

我已经安装了

protobuf

包，但无法导入它

> pip uninstall protobuf
... uninstalls
> pip install protobuf
... installs. confirm that it's installed:
pip install protobuf
Requirement already satisfied (use --upgrade to upgrade): protobuf in     ./.venv/lib/python3.5/site-packages
Requirement already satisfied (use --upgrade to upgrade): setuptools in ./.venv/lib/python3.5/site-packages (from protobuf)
Requirement already satisfied (use --upgrade to upgrade): six>=1.9 in ./.venv/lib/python3.5/site-packages (from protobuf)

回到

ipython

：

In [1]: from google.protobuf import descriptor as _descriptor
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

ImportError: No module named google.protobuf

我也遇到了同样的问题，并发现了以下建议的解决方法：

1.添加新文件tensorflow/google/init.py：

try:
    import pkg_resources
    pkg_resources.declare_namespace(__name__)
except ImportError:
    import pkgutil
    __path__ = pkgutil.extend_path(__path__, __name__)

    Add namespace_packages to tensorflow/google/protobuf/python/setup.py:

setup(
    name='protobuf',
    namespace_packages=['google'],
    ...
)

重新编译/pip安装。祝你好运

你是从活跃的venv开始的ipython？我不是。但是，在通过pip在venv中本地安装ipython后，同样的错误也会发生。请阅读本文，希望这会有所帮助。

try:
    import pkg_resources
    pkg_resources.declare_namespace(__name__)
except ImportError:
    import pkgutil
    __path__ = pkgutil.extend_path(__path__, __name__)

    Add namespace_packages to tensorflow/google/protobuf/python/setup.py:

setup(
    name='protobuf',
    namespace_packages=['google'],
    ...
)
