【问题描述】:
我下载了Graphviz 2.38 MSI 版本并安装在文件夹C:\Python34 下,然后我运行pip install Graphviz,一切顺利。在系统路径中我添加了C:\Python34\bin。当我尝试运行测试脚本时,在filename=dot.render(filename='test') 行中,我收到了一条消息
RuntimeError: failed to execute ['dot', '-Tpdf', '-O', 'test'], make sure the Graphviz executables are on your systems' path
我尝试将"C:\Python34\bin\dot.exe" 放在系统路径中,但它不起作用,我什至创建了一个新的环境变量"GRAPHVIZ_DOT",其值为"C:\Python34\bin\dot.exe",仍然无法正常工作。我尝试卸载 Graphviz 和 pip uninstall graphviz,然后重新安装并再次 pip install,但没有任何效果。
整个回溯消息是:
Traceback (most recent call last):
File "C:\Python34\lib\site-packages\graphviz\files.py", line 220, in render
proc = subprocess.Popen(cmd, startupinfo=STARTUPINFO)
File "C:\Python34\lib\subprocess.py", line 859, in __init__
restore_signals, start_new_session)
File "C:\Python34\lib\subprocess.py", line 1112, in _execute_child
startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "C:\Users\Documents\Kissmetrics\curves and lines\eventNodes.py", line 56, in <module>
filename=dot.render(filename='test')
File "C:\Python34\lib\site-packages\graphviz\files.py", line 225, in render
'are on your systems\' path' % cmd)
RuntimeError: failed to execute ['dot', '-Tpdf', '-O', 'test'], make sure the Graphviz executables are on your systems' path
有人有这方面的经验吗?
