我在macOS 10.10.5上安裝pygraphviz時遇到了麻煩。我有一個Python 2.7.x的全功能安裝，我想運行test example of queueing-tool，這需要installing pygraphviz using pip。PIP安裝pygraphviz失敗：pygraphviz的建築輪失敗
當執行命令pip install pygraphviz，我得到以下漫長的錯誤消息：

我不確定如何解決上述錯誤。所有其他的Python軟件包，比如numpy或者networkx，都可以直接安裝。任何幫助將不勝感激。提前致謝。
原因是：在pkg-config搜索路徑中未找到軟件包libcgraph。也許你應該將包含'libcgraph.pc'的目錄添加到PKG_CONFIG_PATH環境變量中。你可以使用谷歌找到解決方案。 – Andrew
你安裝了libcgraph嗎？ – Goyo
