Done E: Unable to locate package cmake E: Unable to locate package pkg-config E: Unable to locate package libcairo2-dev E: Unable to locate package libjpeg-dev E: Unable to locate package libgif-dev# 1. 先更新软件源索引（关键步骤，解决「无法定位包」的核心） apt update -y # 2. 再执行依赖安装，然后再在Web端正常安装即可 apt-get install -y cmake pkg-config libcairo2-dev libjpeg-dev libgif-dev5.处理结果
