我一直在使用discord.js 制作一个discord 机器人。我想在画布上制作一条欢迎信息,然后制作完成后,除了画布上的文字之外,它一切正常。事情是这样的:

我在谷歌上搜索了很多,但找不到任何解决方案。我得到的错误是(字体配置错误:无法加载默认配置文件)。我知道这意味着我的系统中没有字体,但如何添加它们。我正在使用 repl.it。

它应该在 node-canvas 2.0+ 中工作。签出新Canvas.registerFont方法:
https: //github.com/Automattic/node-canvas/#registerfont
要使用未作为系统字体安装的字体文件,请使用registerFont()Canvas 注册该字体。这必须在创建 Canvas 之前完成。
const { registerFont, createCanvas } = require('canvas')
registerFont('./fontFolder/comicsans.ttf', { family: 'Comic Sans' })
const canvas = createCanvas(500, 500)
const ctx = canvas.getContext('2d')
ctx.font = '12px "Comic Sans"'
ctx.fillText('Everyone hates this font :(', 250, 10)

例子:
TTF 文件将具有不同的字体名称。所以只有'Roboto'这里。否则它不起作用。
registerFont('./fonts/Roboto-Medium.ttf', {family: 'Roboto'})

不要将 fontName 定义为'Medium 28px Roboto'。这是行不通的。
ctx.font = '12px Roboto Medium';
