无法导入已安装的python (blink1)

Question

与this question类似，我正在尝试在blink1上安装blink1库。

但不管我怎么努力，我都会得到：

>>>import blink1

Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    import blink1
ImportError: No module named blink1

我通过pip安装了它，据我所知，它在正确的路径上：

pi@raspberrypi ~ $ ls /usr/local/lib/python2.7/dist-packages/
blink1                     python_jenkins-0.4.8.dist-info
blink1-0.0.12.dist-info    pyusb-1.0.0rc1.egg-info
blink1_tests               setuptools
click                      setuptools-18.3.1.dist-info
click-5.1.dist-info        six-1.9.0.dist-info
configobj-5.0.6.dist-info  six.py
configobj.py               six.pyc
configobj.pyc              usb
easy_install.py            validate.py
easy_install.pyc           validate.pyc
jenkins                    _version.py
_markerlib                 _version.pyc
pbr                        webcolors-1.5.dist-info
pbr-1.7.0.dist-info        webcolors.py
pip                        webcolors.pyc
pip-7.1.2.dist-info        wheel
pkg_resources              wheel-0.24.0.dist-info

我不知道我现在还应该尝试什么..。

编辑:它似乎也不适用于pyhthon3：

Python 3.2.3 (default, Mar  1 2013, 11:53:50) 
[GCC 4.6.3] on linux2
Type "copyright", "credits" or "license()" for more information.
>>> import blink1
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>

    import blink1
ImportError: No module named blink1

$ sudo pip-3.2 install blink1
Requirement already satisfied (use --upgrade to upgrade): blink1 in /usr/local/lib/python3.2/dist-packages

编辑2:最后一个问题可能与以下事实有关:在安装过程中，sys.path只包含2.7库，而不包含v3 dist包.

Answer 1

/usr/local/lib/python2.7/dist-packages/blink1/中缺少文件__init__.py

如果你跑

touch /usr/local/lib/python2.7/dist-packages/blink1/__init__.py

它应该开始起作用了。
