无法在 nativescript 上安装 nativescript-ffmpeg-plugin

Question

运行 ns plugin add nativescript-ffmpeg-plugin 产生以下错误。

手动安装 nativescript-hook（即 npm i nativescript-hook --save-dev）允许安装此插件，但尝试在 iOS 上构建应用程序失败并出现以下错误：

我试过这个：

Mac开发环境
iOS 14
模拟器：iPhone8

Nativescript 详细信息：

CLI: 7.0.8
跨平台模块：7.0.5
运行时间：7.0.0
插件：

  "dependencies": {
    "@nativescript/core": "~7.0.0",
    "@nativescript/theme": "~2.3.0",
    "nativescript-ffmpeg-plugin": "0.0.2",
    "nativescript-vue": "~2.8.1"
  },
  "devDependencies": {
    "@babel/core": "~7.11.6",
    "@babel/preset-env": "~7.11.5",
    "@nativescript/ios": "7.0.0",
    "@nativescript/webpack": "~3.0.3",
    "babel-loader": "~8.1.0",
    "nativescript-hook": "^0.2.5",
    "nativescript-vue-template-compiler": "~2.8.1",
    "node-sass": "^4.14.1",
    "vue-loader": "~15.9.3"
  },

您可以通过执行以下操作轻松重现问题：

ns create ffmpeg --vue
cd ffmpeg
npm i nativescript-hook --save-dev
ns plugin add nativescript-ffmpeg-plugin
npm run debug-ios

有没有人最近成功安装了插件并且有解决这些问题的任何提示？

Answer 1

查看 nativescript-ffmpeg-plugin 问题和插件的最后修改，似乎不是 NS7 ready. try to downgrade to nativescript@6 or create a PR fot this plugin to make it compatible with NS7。

Answer 2

我安装了 nativescript-ffmpeg-plugin-fixed，它在 NS7 上没有问题。
