您好，我想为 discord.js Bot 安装 Canvas 。
当我尝试使用以下命令安装 Canvas 时npm install canvas我收到以下错误:

pi@server:~/Bots/Discord/Java $ npm install canvas

有人知道我为什么会收到这个错误吗？
我在 Raspberry pi 3B 上使用 Node 12.18.4

根据node-canvas wiki , 您需要从 apt 安装一些依赖项。
只需运行:

sudo apt-get 更新

sudo apt-get install build-essential libcairo2-dev libpango1.0-dev libjpeg-dev libgif-dev librsvg2-dev

安装这些 Canvas 后就安装好了。
