800A03EA javascript 语法 JScript 编译错误

Question

关于 JScript 和节点，我的计算机出现了一个非常烦人的编译问题，我已经尝试了互联网提供的几个说明，但问题似乎仍然存在。

光盘>项目
npm init还行
npm install -g 并且本地正常
npm start > 启动问题：脚本 > app.js 或 node app.js 正常

如果它运行s 我收到 Windows 主机服务器错误 #800A03EA syntax/compilation 问题。

但是，如果我运行代码 npx http-server，我可以毫无问题地完成我的 PWA 项目。

我已经尝试了几个 'fix' 工具，修复，注册表验证，但其中 none 似乎可以解决问题。

JScript（由 windows 脚本宿主解释，WSH）与 JavaScript（由 node* 解释）不同。

提到的错误听起来好像 Windows 脚本宿主的 JScript 解释器试图执行 JavaScript 用于节点的文件。

确保您运行您的代码使用节点 (node app.js) 而不是 WSH。 windows 中 *.JS 的默认文件关联是 WSH，因此双击或仅运行ning app.js 将运行 WSH。

还要确保 package.json 中的 start 命令实际上设置为 node app.js，我感觉它只设置为 app.js.

... 
"scripts": {
  "start": "node app.js"
} 
...

那么，npm start 应该可以。

*：当然 node 不是 Javascript 的唯一解释器，但它是这里相关的解释器。

在js文件开头添加这一行：

#!/usr/bin/env node

它会告诉你的系统使用哪个解释器运行文件
