title: Install ROS Kinetic on MacOS under a separate Anaconda environment
body: <p>I'm installing ROS Kinetic on MacOS Sierra 10.12.6 under a seperate environment under Python Anaconda distribution.</p>
  
  <p>Here is my python version(my seperate python environment in Anaconda is called "ros-kinetic"):</p>
  
  <pre><code>(ros-kinetic)  jizhe@jizhedeMacBook-Pro  ~/ros_catkin_ws  python --version
  Python 3.6.4 :: Anaconda, Inc.
  </code></pre>
  
  <p>I followed the guide: <a href="http://wiki.ros.org/kinetic/Installation/OSX/Homebrew/Source" rel="nofollow noreferrer">http://wiki.ros.org/kinetic/Installation/OSX/Homebrew/Source</a>.</p>
  
  <p>When I execute the "rosdep install" command, I got the following error:</p>
  
  <pre><code>(ros-kinetic)  jizhe@jizhedeMacBook-Pro ~/ros_catkin_ws  rosdep install --from-paths src --ignore-src --rosdistro kinetic -y
  ERROR: the following packages/stacks could not have their rosdep keys resolved
  to system dependencies:
  actionlib: No definition of [python-wxtools] for OS [osx]
  catkin: No definition of [google-mock] for OS [osx]
  roslisp: No definition of [google-mock] for OS [osx]
  </code></pre>
  
  <p>Obviously, there is something wrong with the package "python-wxtools" and "google-mock".</p>
  
  <p>I've already install the wxpython via "brew install wxpython", and here is the wxpython info:</p>
  
  <pre><code>(ros-kinetic)  jizhe@jizhedeMacBook-Pro  ~/ros_catkin_ws  brew info wxpython
  wxpython: stable 3.0.2.0 (bottled)
  Python bindings for wxWidgets

  ==&gt; Dependencies
  Required: wxmac ✔
  ==&gt; Caveats
  Python modules have been installed and Homebrew's site-packages is not
  in your Python sys.path, so you will not be able to import the modules
  this formula installed. If you plan to develop with these modules,
  please run:
  mkdir -p /Users/jizhe/Library/Python/2.7/lib/python/site-packages
    echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' &gt;&gt; /Users/jizhe/Library/Python/2.7/lib/python/site-packages/homebrew.pth
  </code></pre>
  
  <p>And I've already run the command:</p>
  
  <pre><code>$ mkdir -p ~/Library/Python/2.7/lib/python/site-packages
  $ echo "$(brew --prefix)/lib/python2.7/site-packages" &gt;&gt; ~/Library/Python/2.7/lib/python/site-packages/homebrew.pth
  </code></pre>
  
  <p>So, what's wrong with the package "google-mock" and "python-wxtools", how can I solve this problem?</p>
