pidgin-latex我通过安装没有出现任何错误apt-get，并且 pidgin 前后运行良好。插件已激活。我遇到的唯一问题是（几乎）每次应该显示 Latex 消息时，都会弹出以下消息并且文本不会转换。例如，发送消息后$$测试$$弹出此错误消息：
读取生成的图像时出错！
Datei »/tmp/purpleA0SRPY.png« konnte nicht geoöffnet werden: Datei oder Verzeichnis nicht gefunden
第二段是德语，意思是
无法打开文件 /tmp/purpleA0SRPY.png：找不到文件或目录
这就是我启动 pidgin 的命令行所说的：

这就是洋泾浜日志所说的：

但实际上我得到的只是$$测试$$而不是 Latex 所需的渲染输出。
