我所做的操作是将 'live2d_path' 改为我本地的资源路径

可以提供你的网站地址吗？看图片比较难定位问题的具体原因

同样报错，也是本地运行的，感谢大佬帮忙看看

文件结构：

├── index.html
└── dist/
    ├── autoload.js
    ├── waifu.css
    ├── live2d.min.js
    ├── waifu-tips.js
    └── waifu-tips.json

autoload.js文件

// live2d_path 参数建议使用绝对路径
const live2d_path = "./dist/";
//const live2d_path = "/live2d-widget/";

// 封装异步加载资源的方法
function loadExternalResource(url, type) {
	return new Promise((resolve, reject) => {
		let tag;

		if (type === "css") {
			tag = document.createElement("link");
			tag.rel = "stylesheet";
			tag.href = url;
		}
		else if (type === "js") {
			tag = document.createElement("script");
			tag.src = url;
		}
		if (tag) {
			tag.onload = () => resolve(url);
			tag.onerror = () => reject(url);
			document.head.appendChild(tag);
		}
	});
}

// 加载 waifu.css live2d.min.js waifu-tips.js
if (screen.width >= 768) {
	Promise.all([
		loadExternalResource(live2d_path + "waifu.css", "css"),
		loadExternalResource(live2d_path + "live2d.min.js", "js"),
		loadExternalResource(live2d_path + "waifu-tips.js", "js")
	]).then(() => {

			tools: ["hitokoto", "asteroids", "switch-model", "switch-texture", "photo", "info", "quit"]
		});
	});
}

前端文件：

报错的代码是这里：

		initWidget({❌

同样遇到问题，已经解决。

我的解决方法是在根目录下的 rollup.config.js 的第 37 行左右，将 input 项修改为 build/waifu-tips.js 即可解决。

改完后：

export default {
  input: 'build/waifu-tips.js',
  output: {
    name: 'live2d_widget',
    file: 'dist/waifu-tips.js',
    format: 'iife',
  },
  plugins: [
    nodeResolve(),
    string({
      include: '**/*.svg',
    }),
    terser(),
  ],
  context: 'this',
};

@panedioic 你好，我目前也遇到了類似了，但照著你的方法將input項改為build/waifu-tips.js依然會報此問題耶

@panedioic

@whitebear13579 你也是 initWidget is not defined 吗？修改后 npm run build 然后在浏览器刷新一下缓存试试？或者在 build/waifu-tips.js里加一些 console.log 来检查代码有没有执行到这里

@whitebear13579

對，我也同樣是遇到 initWidget is not defined 的問題，我嘗試修改完 build/waifu-tips.js 並添加 console.log("Waifu-tips.js loaded.") 至 build/waifu-tips.js 中
Image

重新 npm run build 後還是依然有 initWidget is not defined 的問題
Image
且貌似 build/waifu-tips.js 與 build/index.js 並未被正確加載，因為 console中沒有出現預期的 Waifu-tips.js loaded.

@whitebear13579

我上面的回复有一些问题。应该修改的是 src/waifu-tips.ts 而不是 build/waifu-tips.js，因为 build/waifu-tips.js 会在 npm run build 后被修改。

你还可以修改 src 下的其他的 ts 文件，看看是否只有 src/waifu-tips.ts 不会被打包进 dist/waifu-tips.js 中，进一步定位问题。

@whitebear13579

試了一下，發現 src 目錄底下所有的 .ts 文件都不會被打包 😅

@whitebear13579

我嘗試在 autoload.js 中的 33 行嘗試新增 loadExternalResource("../build/waifu-tips.js") 載入資源，瀏覽器確實沒有報錯了，但 live2D 組件依然沒有成功加載出來 😅

@whitebear13579 build/waifu-tips.js 使用了 import 语法，不能在前端中使用。还是建议检查打包工具的输入输出路径是否有误。
