Mac下安装最新版本的Graphviz

因为版本兼容问题，Mac下Graphviz以前一直装的是低版本的2.36。高版本的安装方法以下：

 

一、log in & download Xcode an Xcode Command Line Tools from
https://developer.apple.com/downloads/
install Xcode and the Xcode Command Line Tools

二、agree to Xcode license in terminal:
sudo xcodebuild –license

三、get MacPorts pkg installer for your version of osx from
https://www.macports.org/install.php#installing
install MacPorts for your version of osx

 

四、in terminal:
sudo port -v selfupdate

五、install graphviz via MacPorts. in terminal:
sudo port install graphviz-gui

installed gui application can be found here: /Application/Macports/Graphviz.app

相关MacPorts的命令说明能够看： http://blog.csdn.net/moliyll/article/details/7898600

 

我这里因为有以前的版本的 graphviz， 安装时候提示：

$ sudo port install graphviz-gui
--->  Computing dependencies for graphviz-gui
--->  Cleaning graphviz-gui
--->  Scanning binaries for linking errors
Warning: Error parsing file /Applications/MacPorts/Graphviz.app/Contents/MacOS/Graphviz: Error opening or reading file
--->  No broken files found.

解决方法：

先用 AppCleaner 清除以前的安装文件。

再用 sudo port uninstall graphviz-gui 卸载以前的安装依赖。

而后从新安装就能够安装成功了 2.40.1。

 

另外在作安装时，提示我要设置一些默认python 。 执行下面任何一个命令均可以完成。

--->  Some of the ports you installed have notes:
  python27 has the following notes:
    To make this the default Python or Python 2 (i.e., the version run by the
    'python' or 'python2' commands), run one or both of:
   
        sudo port select --set python python27
        sudo port select --set python2 python27
   
    ##############################################################
    # IF YOU ARE USING PYTHON FROM THE TERMINAL, PLEASE INSTALL:
    #   py27-readline
    # TO AVOID A LIBEDIT / PYTHON INTERACTION ISSUE.
    # REF: https://trac.macports.org/ticket/48807
    ##############################################################

 

这种方式安装完成后， GUI和命令行都是升级到了 2.40.1 版本了。

 

$ dot -V
dot - graphviz version 2.40.1 (20161225.0304)
