3.测试

cmd 运行dot -version

• 不是内部或外部命令。添加安装路径到系统环境变量
  
• 错误

dot - graphviz version 2.41.20170921.1950 (20170921.1950)

There is no layout engine support for "dot"

Perhaps "dot -c" needs to be run (with installer's privileges) to register the plugins?

运行dot -c ，若出现以下图成功。

dot -c报错

dot -c error: failed to open d:\graphviz 2.44.1\bin\config6 for write.

使用管理员打开终端，运行命令dot -c
