🎨 canvas 安装慢、安装失败的解决方法

📦 canvas 的安装过程

1. npm 下载: 在仓库中下载 canvas 包。
2. 执行 install 命令: 执行 canvas 的 package.json 中的安装命令 (node-pre-gyp install --fallback-to-build)。
3. 下载预编译文件: node-pre-gyp 下载 canvas 已编译好的 macOS、Linux 和 Windows 的二进制文件。如果预构建的二进制文件不存在或不可用，则回退到从源代码构建。
4. 编译为可用模块: node-gyp 编译为当前平台可用的 node 模块。
