Question

我试图在我的cordova应用程序中添加一个插件，但是我收到一条错误消息＆＃34;平台＆＃34; ios＆＃34;似乎不是一个有效的cordova平台。它缺少API.js. ios不受支持。＆＃34;

node --version
v9.2.0

cordova --version
8.0.0

这是我正在运行的命令

cordova plugin add cordova-plugin-appinfo

完整输出：

Installing "cordova-plugin-appinfo" for ios
Unable to load PlatformApi from platform. Error: Cannot find module 'unorm'
Failed to install 'cordova-plugin-appinfo': Error [ERR_UNHANDLED_ERROR]: Unhandled error. (The platform "ios" does not appear to be a valid cordova platform. It is missing API.js. ios not supported.)

我确定这是一个有效的Cordova项目，iOS平台似乎运行正常（我可以在iPhone上构建和运行）。

Answer 1

尝试更新ios平台后遇到相同的错误。事实证明，node_modules下载缓存中存在一些损坏。我可以通过再次尝试解决此问题：

let a = [ 1,2,2,3,5,4,2,5,7,9,5,3,8,10 ]
let indices = a.enumerated().withPreviousAndNext.compactMap { values -> Int? in
    let (prev, cur, next) = values
    return (cur.1 < (prev?.1 ?? Int.min) && cur.1 < (next?.1 ?? Int.min)) ? cur.0 : nil
}
indices // [6,11]

Answer 2

将文件从一台计算机复制到另一台计算机时出现此错误。

这些行固定

cordova platform rm ios

cordova platform add ios

Cordova无法添加插件：错误：无法找到模块＆＃39; unorm＆＃39;
