我想用python来crud

rrd

，但是当我

pip安装python rrdtool

时。警告如下：

我试过很多次了，谁能告诉我

我通过@Stephen Ingram的建议解决了这个问题

1.安装rrdtool（使用

brew安装rrdtool

）

2.检查

cairo、pango

3.run

python setup.py安装

看起来它正在寻找需要先构建并安装rrdtool的rrd库。您是否尝试过

brew安装rrdtool

？我认为它应该同时安装rrd和python绑定。如果您不想使用

brew

，那么您可以先尝试从源代码构建，然后运行上面的pip命令。它可以工作。非常感谢。检查一下<代码>导入rrdtool您所说的检查cairo和pango是什么意思？
