我按照这里的指示使用Homebrew安装了Octave。
当我尝试生成一个图时，会收到以下消息：
Fontconfig error: Cannot load default config file
warning: could not match any font: *-normal-normal-10
warning: called from
axes at line 66 column 10
gca at line 58 column 9
newplot at line 148 column 8
surf at line 70 column 9
sombrero at line 65 column 5
接下来，我会收到一长串类似以下的消息：
warning: ft_render: unable to load appropriate font
warning: could not match any font: *-normal-normal-10
通常情况下，这个情节只会出现一次，但如果我再次调用它，Octave 就会弹出以下消息并退出。
panic: Segmentation fault: 11 -- stopping myself...
attempting to save variables to 'octave-workspace'...
warning: unable to open 'octave-workspace' for writing...

Segmentation fault: 11
在讨论类似错误时，我经常看到对/etc/fonts/fonts.conf的引用。 我的/ etc目录中没有包含字体子目录。 这可能是问题的根源，但我不知道如何解决它。 当我运行brew install fontconfig时，我收到Warning: fontconfig-2.11.1_1 already installed的提示。 当我运行sudo find / -name fonts.conf时，我会得到/opt/X11/lib/X11/fontconfig/fonts.conf。
brew doctor产生了以下警告，这些警告可能与问题有关，但我不知道如何解决（除非卸载Anaconda）：
Warning: Anaconda is known to frequently break Homebrew builds, including Vim
and MacVim, due to bundling many duplicates of system and Homebrew-available
tools.
If you encounter a build failure please temporarily remove Anaconda
from your $PATH and attempt the build again prior to reporting the
failure to us. Thanks!
Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.
Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:
/Users/greg/anaconda/bin/curl-config
/Users/greg/anaconda/bin/freetype-config
/Users/greg/anaconda/bin/libdynd-config
/Users/greg/anaconda/bin/libpng-config
/Users/greg/anaconda/bin/libpng16-config
/Users/greg/anaconda/bin/python-config
