在Python中安装RAKE时出现命名空间包错误

Question

When I am trying to install RAKE - Rapid Automatic Keywords Extraction I am getting the following error on both Windows 8 and Ubuntu 14.04 with Python 2.7:

error: Namespace package problem: rake is a namespace package, but its
`__init__.py` does not call declare_namespace()! Please fix it.
(See the setuptools manual under "Namespace Packages" for details.)

I have tried installation using pip as well as manual installation with python install setup.py .

What does this error mean and how do I fix it?

Answer 1

I had the above error when trying to install rake with pip install rake . Searching for the proper package name with pip search rake gave a list including python-rake . Running the line pip install python-rake fixed the error / properly installed rake.

Note the import of rake uses all caps (ie, import RAKE ), as shown in the project's repo .

Answer 2

Actually the module is under RAKE as RAKE. I tried the following and it worked.

    import RAKE.RAKE as rake

    rake.Rake("path/to/stop/list")
    ...
