我的程序结构发生了一些变化,由于其复杂性,我无法准确指出问题所在。自从我的应用程序崩溃并且不再工作以来,我尝试了不同的方法,例如删除节点模块包并重新安装它们但仍然无法工作。 无论何时我尝试运行 npm start ,我都会收到以下错误:
以下是我的 package.json 文件

react-scripts start
生成错误Error: Cannot find module '../scripts/start'
我不确定在create react app
期间是什么引起了问题,但是我发现最有效的方法是删除nodes_module
文件夹,然后在终端运行npm install
中项目目录。

更新create-react-app
为我解决了这个问题。
npm install -g create-react-app@latest
还请记住,它不是不是 node start
,是npm start
答案 2 :(得分:0)
我在 WSL2 中工作时遇到同样的问题,我将 reactjs-app
复制到主目录到 WSL2。因此,要在那里工作时解决它,请删除 node_modules
并在应用目录中再次运行 npm install
。

我想我得到了答案。脚本/文件夹被意外放在错误的目录中,它应该在我的应用程序的根文件夹中。 我将它放在根文件夹中,应用程序现在正在运行。谢谢你的领导。
