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？

我已经在 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：'（随意尝试该项目：https : //github.com/EMDevelop/j2c

当我运行时npm start，我收到以下消息

> just2connect@0.1.0 start C:UsersEdDesktopCodingReactj2c
> 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

这很奇怪，因为我有"craco": "0.0.3"一个依赖项，并且"start": "craco start"作为我的package.json.

我也有craco.config项目@craco中的node_modules文件和文件夹中的文件夹。

当我再次尝试安装 craco ( npm i @craco/craco) 并运行时npm start，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npm start再次尝试运行时，它给了我错误，就好像我从未再次安装过 craco：

C:UsersEdDesktopCodingReactj2c>npm start

> just2connect@0.1.0 start C:UsersEdDesktopCodingReactj2c
> craco start

任何帮助将不胜感激！！拉我的头发，我是 Windows 的新手。
