Vue.js 在浏览器中出现意外令牌，但 npm run build 没有错误 [英] Vue.js unexpected token in browser but npm run build with no errors
问题描述
我正在处理其他人启动的 vue.js 项目，并将其放在生产服务器上.npm run build 编译没有错误.但是当我尝试在浏览器中运行该项目时，我得到一个
未捕获的语法错误:意外标记<这是index.html
我得到了所有 3 个 .js 资产文件.
请求的服务器控制台输出.看起来文件正在返回:
GET/static/css/app.d79e04c40fa9145fe427147ef17b4576.css 200 1.580 毫秒 - 820获取/static/js/manifest.2ae2e69a05c33dfc65f8.js 200 3.095 毫秒 - 820获取/static/js/app.19024fb1db555dd8417b.js 200 3.157 毫秒 - 820获取/static/js/vendor.bfe581b46b720086662f.js 200 3.429 毫秒 - 820知道如何解决这个问题吗?
在不同的选项卡上打开每个脚本的 URL(或检查开发人员工具的网络选项卡)，这些 URL 可能返回 404(或某些其他错误代码)和一个 HTML 错误页面.
因此您的代码尝试将这些 HTML 错误页面解析为 JavaScript 代码，从而产生该错误.
它得到 Uncaught SyntaxError: Unexpected token < 因为它试图将 HTML 内容(例如 ...)解析为 JavaScript 代码.>
运行下面的代码片段并在控制台查看错误.

Here's the index.html

I get that for all 3 .js asset files.
Server console output on the request. Looks like the files are getting returned:
GET /static/css/app.d79e04c40fa9145fe427147ef17b4576.css 200 1.580 ms - 820
GET /static/js/manifest.2ae2e69a05c33dfc65f8.js 200 3.095 ms - 820

GET /static/js/vendor.bfe581b46b720086662f.js 200 3.429 ms - 820
Any idea how to fix this?
Open the URLs of the scripts each on a different tab (or check the network tab of the developer tools), those URLs are probably returning a 404 (or some other error code) and a HTML error page.
So your code tries to parse those HTML error pages as JavaScript code, thus yielding that error.
It gets Uncaught SyntaxError: Unexpected token < because it tries to parse the HTML content (e.g. <html> ...) as JavaScript code.
Run the snippet below and see the error at the console.
<script type=text/javascript src=https://stackoverflow.com></script>
Check the console: "Uncaught SyntaxError: Unexpected token <"
