homebrew - RRDTool 'graph' 命令抛出 Glib 和 Pango 错误，在 Mac OS X 上与 Homebrew 一起安装

Question

问题是：

如何让 RRDTool 在 Mac OS X 上生成图表？

我在 Mac OS x 10.6.8 上rrdtool安装。homebrew

我能够创建数据库、更新一些数据并获取数据，但我无法为其生成图表。

看起来和 有glib问题pango。

这两个库都安装了homebrew.

我在用着：

• RRDTool 1.4.7
• 油嘴滑舌 2.34.2
• 盘古 1.30.1

当我运行这个：

rrdtool create datafile.rrd DS:packets:ABSOLUTE:900:0:10000000 RRA:AVERAGE:0.5:1:9600 RRA:AVERAGE:0.5:4:9600 RRA:AVERAGE:0.5:24:6000
rrdtool update datafile.rrd N:12322
rrdtool graph graph.png DEF:pkt=datafile.rrd:packets:AVERAGE LINE1:pkt#ff0000:Packets

我得到：
