我尝试将带有以太坊资金的私钥导入到元掩码 linea 中，但收到零余额错误。
因此，我尝试搜索如何创建要导入的 json 文件，但是在寻找 json 文件的模板时，该模板主要是一个文本文件，已重命名为可编程的 .json 文件，然后我可以上传和/或导入到钱包中但是我需要知道相关的钱包导入格式？！所以我搜索了如何导出json格式文件，但是当我尝试搜索导出功能时，我被带到了cmd输入命令，但现在有两个应用程序打开，一个是cmd，另一个是mozilla浏览器或chrome浏览器？！ https://ethereum.stackexchange.com/questions/16797/export-metamask-account-to-json-file
但是，当我尝试在 linux cmd 控制台中运行 npm 代码执行时收到错误。

这是第一个问题，第二个问题只是 json 文件模板格式可编辑文本格式，用于将资金上传到钱包地址，然后绕过所需的任何安全费用，以完成余额初始化更新等任务，然后也是相关发送及相关接收。有一个示例说明在哪里导入文件
然后是半代码半文本讨论示例 -https://github.com/MetaMask/metamask-extension/issues/1232;https://www.w3schools.com/js/js_json_intro.asp;https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Objects/JSON
