Question

我试图在nativescript中运行openpgp库以使用其加密，在尝试使用它安装并运行它之后，出现此错误

JS: Angular is running in the development mode. Call enableProdMode() to enable the production mode.
JS: ERROR Error: Uncaught (in promise): Error: com.tns.NativeScriptException: Failed to find module: "crypto", relative to: app/tns_modules/

我的package.json就是这样

如果有人知道某事，请您告诉我，如果您知道如何在本机脚本中使用开放式pgp库，那将非常有帮助

Answer 1

如果您的NPM程序包依赖于Node引擎中的程序包，例如crypto，则它将不能与NativeScript一起使用。

一种解决方法是使用nativescript-nodeify插件，该插件内置支持Node引擎中的少数软件包，例如fs，crypto等，

Answer 2

您可以使用我的openpgp.js v2.5.9的分支，其中包括一些polyfill，以使openpgp.js在Nativescript上工作。您只需要执行npm install github:mohammadrafigh/nativescript-openpgpjs#openpgp2并像这样导入openpgp：

import * as openpgp from "openpgp/dist/openpgp";

我将使用来自openpgp 4的最新更改来更新此存储库，并尽快将其作为单独的软件包发布在npm上，但现在确保您使用的是openpgp2分支而不是master。
