使用 http-server 激活服务器出现 TypeError: Readable.from is not a function

Question

我目前正在将 PWA 添加到我的新 Angular 项目中。

C:\Users\alan_yu\angular-pwa>http-server -p 8080 -c-1 dist/angular-pwa

Starting up http-server, serving dist/angular-pwa

http-server version: 14.0.0

http-server settings: 
CORS: disabled
Cache: -1 seconds
Connection Timeout: 120 seconds
Directory Listings: visible
AutoIndex: visible
Serve GZIP Files: false
Serve Brotli Files: false
Default File Extension: none

Available on:
  http://192.168.16.91:8080
  http://192.168.56.1:8080
  http://192.168.99.1:8080
  http://127.0.0.1:8080
Hit CTRL-C to stop the server

但加载网页后，我在控制台中收到错误：

环境版本

操作系统类型：Windows 7 专业版

节点版本：V12.2.0

http服务器版本：V14.0.0

Answer 1

stream.Readable.from新增功能：node v12.3.0、v10.17.0

将节点从 V12.2.0 更新到 v13.13.0（至少 v12.3.0）后，http 服务器运行良好。

参考：Node.js 文档

Answer 2

正如艾伦的回答提到的；这是node版本问题，如果您不想升级节点版本（或者不能像我的情况一样），您可以将http-server版本降级到13.1.0；这对我有用。

npm i -g http-server@13.1.0
