javascript - 如何解决 webpack“Mod

Question

我正在使用 React 并且刚刚添加了这个模块 ccxt。在添加模块之前一切都很好。该模块安装良好。后来，我将这一行添加到脚本中:

const ccxt = require('ccxt');

当我发出 npm start 时，它会抛出一个错误:

我尝试“npm install”并收到错误(即使 npm install --save ccxt 运行正常):

clean-webpack-plugin: /home/marcus/development/nodestuff/crypto-crawler/public/dist has been removed.
ModuleParseError: Module parse failed: /home/marcus/development/nodestuff/crypto-crawler/node_modules/ccxt/js/allcoin.js Unexpected token (60:10)
You may need an appropriate loader to handle this file type.

这告诉我什么或者您如何解决这个问题有什么建议吗？

Answer 1

错误Error: listen EADDRINUSE 127.0.0.1:8080似乎表明您正在尝试在端口 8080 上运行两个进程。

这里没有足够的关于您的开发环境/应用程序架构的信息来告诉您具体要做什么，但听起来您需要配置您的应用程序服务器或 cctx 以使用不同的端口。我的猜测是cctx默认使用端口8080。

尝试搜索 8080在您的应用程序的代码库中并将其更改为其他内容。或者在 cctx 文档中查找配置选项以指定其运行的端口。

此外，运行 lsof -i | grep 8080查看您的计算机上是否有任何其他进程正在使用端口 8080。

希望这有帮助，祝你好运!
