【问题描述】：

我一直在竭尽全力为 ios 和 android 构建我的 ionic 应用程序。我已经多次添加和删除平台。升级和降级了我的 ionic 应用程序和 java JDK，但没有任何效果。现在常见的错误似乎与插件“cordova-custom-config”有关。

当尝试通过命令$ sudo ionic cordova platform add ios@latest --fetch --save --verbose添加ios平台时，错误是：

Discovered plugin "cordova-custom-config" in config.xml. Adding it to the project

Failed to restore plugin "cordova-custom-config" from config.xml. You might need to try adding it again. Error: Failed to fetch plugin cordova-custom-config@^5.0.1 via registry.
Probably this is either a connection problem, or plugin spec is incorrect.
Check your connection and plugin name/version/URL.

[ERROR] Exception:

尝试通过$ sudo ionic cordova platform add android@6.3.0 --fetch --save --verbose the error 命令添加android 平台时与ios 相同。请注意，我添加的是 android@6.3.0 而不是 android@latest，因为最新 (7.0.0) 有问题。

当我尝试通过命令$ sudo cordova plugin add cordova-custom-config --fetch --verbose 自行添加 cordova-custom-config 插件时，错误是：

【解决方案1】：

尝试安装到以前包含旧版本插件的项目时似乎是一个问题。尝试清除以前的残留物：

rm -Rf node_modules/cordova-custom-config and rm -Rf plugins/cordova-custom-config

如果仍有问题，请使用 new cordova-fetch option 安装

cordova plugin add cordova-custom-config --fetch
