我有点手足无措,而且在网络开发方面的背景非常薄弱。最近,我不得不接手一位离开的同事的工作,他一直在研究网络开发和学习所有工具,同时试图完成我们正在处理的网站。该项目使用 webpack 和 react,当一切都出错时我试图添加 redux。我将 webpack 和一些插件更新为最新版本,以便与 redux 一起使用。更新后,我在尝试 npm start 时遇到了一个又一个问题。我应该指出,之前,我一直在从事该项目(没有 redux)并且对网站进行了一些更改并且一切正常。自从尝试更新以来,我什至无法运行开发服务器。我已经研究这个问题大约一个星期了,并尝试尽可能多地了解所有启动文件的实际功能,但尚未找到解决方案。有什么建议吗?
