【中文标题】如何在 Electron 中安装 MetaMask 扩展?【英文标题】:How can I install the MetaMask extension in Electron? 【发布时间】:2018-01-10 16:33:19 【问题描述】:我已经成功安装了来自https://github.com/aragon/metamask-plugin的扩展
当 Electron 应用程序启动时,我可以看到 MetaMask 插件已加载,但不能用它做太多事情。有一些错误:

【问题讨论】:
嘿!我有问题。你弄明白了吗?如果是这样,请您发布解决方案。谢谢! 类似错误,但我使用的是 chrome 商店的插件。 【参考方案1】:这两个错误都是函数范围绑定错误。 this.setupMetaMaskPageStream
和 this._runtime.onConnect
函数是从 MetaMaskController 中的其他函数调用的,但它们似乎在没有保留 MetaMask 控制器范围的情况下被调用,默认为全局上下文(因此 window._setupMetaMaskPageStream
)。
没有看到你的代码,很难知道你是如何在错误的上下文中调用这些方法的,但它可能涉及bind
或call
函数。
