就这一句报错么？那你检查一下你最近动过的 fontconfig 配置文件呗。

我最近感觉也没动过，不知道为什么就出错了

目前电报群的大哥又让我做了如下处理，但还是没找到问题。

Re: 【已解决】fc-cache报错

感谢archlinuxcn电报群上依云姐和风语如歌大哥二人的耐心帮助，特别是风语大哥，今天一步一步帮我排查问题，对我这个小白非常有耐心，真的非常感谢，现在我已经解决啦。
问题解决过程：
1.首先风雨大哥先带我做了一下基本的排查，在我上一条评论里已经放出输出结果了，当时并没有头绪。
2.而后依云姐帮我看了用户级和系统级的fonts.conf文件，发现两者也并没有什么问题。
3.依云姐提出要用strace进行问题排查，但我这个小白不太会用，风雨大哥非常耐心的引导我做了如下处理：

$ sudo pacman -S strace

$ strace -o /tmp/log.txt fc-match

这里在/tmp/log.txt中并没有找到 /etc/fonts/fonts.conf相关的信息，发现fontconfig 命令好像是别的软件打包的，因此做了如下验证：

$ /usr/bin/fc-match
NotoSans-Regular.ttf: "Noto Sans" "Regular"

发现系统的fontconfig没有问题，也就是说我目前的fc-* 相关命令不是 /usr/bin/fc-* 里面的而是/opt/anacondda/bin/里的（这个应该是从日志里看出来的），于是看了一下PATH环境变量：

$ echo $PATH
/opt/anaconda/bin:/opt/anaconda/condabin:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:/var/lib/snapd/snap/bin

发现确实是这样，这让我想起我在.zshrc中好像加过一个和anaconda相关的启动项：

source /opt/anaconda/bin/activate root

应该是这个activate加入了环境变量的设置，把它注释掉来验证一下：

fc-cache

没有任何输出，说明已经成功了，这里风雨大哥建议我把这个设置改用alias来实现，我觉得很有道理，于是我调整为：

alias openconda="source /opt/anaconda/bin/activate root"
alias closeconda="conda deactivate"

经过测试，conda启动关闭正常，fc命令在anaconda未激活下也无报错，至此问题解决。

呃，原来又是 anaconda 搞的鬼……之前已经见过好多因为默认激活 anaconda 而导致 ncurses 和 curl 异常的群友了。

Re: 【已解决】fc-cache报错

1. 建议用 miniconda
2. conda config --set auto_activate_base false
