While trying to resolve module http from file /Users/alex/ParkME/node_modules/node-fetch/index.js , the package /Users/alex/ParkME/node_modules/http/package.json was successfully found. However, this package itself specifies a main module field that could not be resolved ( /Users/alex/ParkME/node_modules/http/index.js . Indeed, none of these files exist:但是，这个 package 本身指定了一个无法解析的main模块字段（ /Users/alex/ParkME/node_modules/http/index.js 。事实上，这些文件都不存在：

Is the error coming from your backend or frontend code?错误来自您的后端还是前端代码？ And were the node modules included in the code you got from the other person?您从其他人那里获得的代码中是否包含节点模块？ You can try running npm install command on the directory to update the dependencies if you haven't already.如果尚未更新依赖项，您可以尝试在目录上运行npm install命令来更新依赖项。
