graphviz 无法在python3.4+中无法安装，

 

• Install MSFT C++ compiler.
• Install Anaconda for Win AMD64, Python3.
• Install graphviz for Win.
• Add C:\Program Files (x86)\Graphviz2.38\bin to your PATH environment variable.
• Download pygraphviz-1.3.1-cp34-none-win_amd64.whl.
• Create a Conda environment with Python version 3.4: conda create --name digraphs python=3.4 anaconda.
• Enter the environment: activate digraphs.
• Install pygraphviz using pip: pip install pygraphviz-1.3.1-cp34-none-win_amd64.whl.
• Run example: python ./gviz_simple.py.
• Exit the environment: deactivate

 

1. 设置环境变量 在用户环境变量添加以下一个变量

.建立变量名 GRAPHVIZ_INSTALL_DIR, 值为如C:\Program Files (x86)\Graphviz2.34

2 在系统环境变量 建立变量名PATH中添加Graphviz的bin目录路径，如C:\Program Files (x86)\Graphviz2.34\bin

3.在终端中使用命令 pip  install graphviz （一定要切换到digraphs 环境下）
