安装google-cloud-vision

Question

我是新来的raspberry pi，google cloud，python，对于linux来说有些新鲜，并且想要提供关于如何修复/调试这个问题的建议。当我安装Cloud Vision API Client Libraries for python时出现错误。

似乎这个安装在raspian上打破了pip和pip3。以下是我转载自一个新鲜的问题，请安装raspian的：

pi@raspberrypi:~ $ pip --version 
pip 1.5.6 from /usr/lib/python2.7/dist-packages (python 2.7) 
pi@raspberrypi:~ $ 
pi@raspberrypi:~ $ sudo pip install --upgrade google-cloud-vision 
... 
... 
At the end of the log: 

    Running setup.py install for dill 
    Traceback (most recent call last): 
     File "<string>", line 1, in <module> 
     File "/usr/local/lib/python2.7/dist-packages/setuptools/__init__.py", line 12, in <module> 
     import setuptools.version 
     File "/usr/local/lib/python2.7/dist-packages/setuptools/version.py", line 1, in <module> 
     import pkg_resources 
     File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 70, in <module> 
     import packaging.version 
    ImportError: No module named packaging.version 
    Complete output from command /usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip-build-1dbzT3/dill/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-lUJmAy-record/install-record.txt --single-version-externally-managed --compile: 
    Traceback (most recent call last): 

    File "<string>", line 1, in <module> 

    File "/usr/local/lib/python2.7/dist-packages/setuptools/__init__.py", line 12, in <module> 

    import setuptools.version 

    File "/usr/local/lib/python2.7/dist-packages/setuptools/version.py", line 1, in <module> 

    import pkg_resources 

    File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 70, in <module> 

    import packaging.version 

ImportError: No module named packaging.version 

后来，当我运行点子，我得到这个：

pi@raspberrypi:~ $ pip --version 
Traceback (most recent call last): 
    File "/usr/bin/pip", line 5, in <module> 
    from pkg_resources import load_entry_point 
    File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 70, in <module> 
    import packaging.version 
ImportError: No module named packaging.version 

我不知道如何去解决这个。

在Raspberry Pi上安装云客户端库有一个技巧：首先安装virtualenv和sphinx。以下步骤将帮助您：

sudo apt-get install python-pip virtualenv python-dev 
virtualenv env 
source env/bin/activate 
pip install sphinx 
pip install --upgrade google-cloud-vision 
python
