Question

我对NodeJS使用«Canvas»库有问题。当我在终端中启动此命令时：

node .

终端对此回复：

module.js:549
    throw err;
    ^

Error: Cannot find module '../build/Release/canvas.node'
    at Function.Module._resolveFilename (module.js:547:15)
    at Function.Module._load (module.js:474:25)
    at Module.require (module.js:596:17)
    at require (internal/module.js:11:18)

    at Module.load (module.js:565:32)
    at tryModuleLoad (module.js:505:12)
    at Function.Module._load (module.js:497:3)

我不明白为什么。

这是 index.js 文件：

const Discord = require('discord.js');
const Canvas = require('canvas');

const client = new Discord.Client();

client.once('ready', () => {
	console.log('Ready!');
});

client.on('guildMemberAdd', async member => {
	const channel = member.guild.channels.find(ch => ch.name === 'member-log');
	if (!channel) return;

	const canvas = Canvas.createCanvas(700, 250);
	const ctx = canvas.getContext('2d');

	const background = await Canvas.loadImage('./wallpaper.jpg');
	ctx.drawImage(background, 0, 0, canvas.width, canvas.height);

	ctx.strokeStyle = '#74037b';
	ctx.strokeRect(0, 0, canvas.width, canvas.height);

	ctx.font = '28px sans-serif';
	ctx.fillStyle = '#ffffff';
	ctx.fillText('Bienvenue,', canvas.width / 2.5, canvas.height / 3.5);

	// Add an exclamation point here and below
	ctx.font = applyText(canvas, `${member.displayName}!`);
	ctx.fillStyle = '#ffffff';
	ctx.fillText(`${member.displayName}!`, canvas.width / 2.5, canvas.height / 1.8);

	ctx.beginPath();
	ctx.arc(125, 125, 100, 0, Math.PI * 2, true);
	ctx.closePath();
	ctx.clip();

	const avatar = await Canvas.loadImage(member.user.displayAvatarURL);
	ctx.drawImage(avatar, 25, 25, 200, 200);

	const attachment = new Discord.MessageAttachment(canvas.toBuffer(), 'welcome-image.png');

	channel.send(`Bienvenue sur le serveur, ${member}!`, attachment);
});
client.on('message', async message => {
	if (message.content === '!join') {
		client.emit('guildMemberAdd', message.member || await message.guild.fetchMember(message.author));
	}
});
client.login(SECRET TOKEN);

我在Qwant有搜索帮助，但没有发现任何问题。非常感谢您的帮助。

来自documentation：

Mac OS X v10.11 +：如果您最近更新到Mac OS X v10.11 +，并且在编译时遇到问题，请运行以下命令：xcode-select --install。阅读有关堆栈溢出问题的更多信息。如果您安装了xcode 10.0或更高版本，则要从源代码进行构建，您需要NPM 6.4.1或更高版本。
