@graphviz安装成功!遇到的问题以及解决办法记录

问题1.

win10, pycharm 安装graphviz之后运行代码,出现make sure the Graphviz executables are on your systems’ PATH的错误

解决办法: https://blog.csdn.net/c_daofeng/article/details/81077594

graphviz是个软件,不能单独用Pip安装

首先,下载graphviz的安装包 ,地址:https://graphviz.gitlab.io/_pages/Download/Download_windows.html 安装

设置环境变量: 用户变量:加入Path: C:\Program Files\Graphviz 2.44.1\bin

系统变量:加入Path: C:\Program Files\Graphviz 2.44.1\bin\dot.exe C:\Program Files\Graphviz 2.44.1\bin

重新pip3 install graphviz

重启pycharm

问题1解决,出现问题2.

问题2.

** graphviz.backend.CalledProcessError: Command '[‘dot’, ‘-Tpdf’, ‘-O’, ‘iristree’]

CalledProcessError: Command ‘[‘dot’, ‘-Tpdf’, ‘-O’, ‘BinaryTree.gv’]’ returned non-zero exit status 1. [stderr: b’Format: “pdf” not recognized. Use one of:\r\n’]

解决办法: 管理员身份运行cmd

运行:dot -v 出现问题:There is no layout engine support for “dot”…运行:dot -c 没有提示(成功)再次运行dot -v,出来如下字样,成功!再去运行代码,可以了!

全部运行如下图:
