React 无法启动项目 - 'craco' 未被识别为内部或外部命令

如何解决React 无法启动项目 - 'craco' 未被识别为内部或外部命令

谁能告诉我为什么我不能在开发服务器上启动我的网站项目？

我在 Windows 10 上克隆了一个文件，这曾经在我的 Mac OS 上运行良好......在它死之前:'(随意尝试这个项目：https://github.com/EMDevelop/j2c

当我运行 npm start 时，我收到以下消息

> just2connect@0.1.0 start C:\Users\Ed\Desktop\Coding\React\j2c
> craco start

'craco' is not recognized as an internal or external command,operable program or batch file.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! just2connect@0.1.0 start: `craco start`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the just2connect@0.1.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR!     C:\Users\Ed\AppData\Roaming\npm-cache\_logs\2021-03-26T16_11_19_513Z-debug.log

这很奇怪，因为我有 "craco": "0.0.3" 作为依赖项，而 "start": "craco start" 作为我的 package.json 中的脚本。

我在项目中还有 craco.config 文件，@craco 文件夹中有 node_modules 文件夹。

当我再次尝试安装 craco (npm i @craco/craco) 并运行 npm start 时，出现以下错误，要求我安装依赖项：

这也很奇怪，因为我在 node_modules 文件夹（和 package.json）中拥有大部分这些依赖项：

我担心只是不顾后果地强迫 craco 替换旧版本，然后我是否必须对它给我警告的每个依赖项都这样做？其中大部分依赖项已经存在。

然后，当我再次尝试运行 npm start 时，它给了我错误，就好像我从未再次安装过 craco：

C:\Users\Ed\Desktop\Coding\React\j2c>npm start

> just2connect@0.1.0 start C:\Users\Ed\Desktop\Coding\React\j2c
> craco start

任何帮助将不胜感激！！拔头发，我是 Windows 新手。

解决方法

这对我有用

npm install @craco/craco --save
