解决方案
这对我有用：
Solution
Here's what worked for me:
-
$ ./platforms/ios/cordova/干净 -
$ sudo ionic plug remove cordova-plugin-network-information -
$ sudo ionic plugin add https://github.com/apache/cordova-plugin-network-information -
$ sudo ionic build ios
$ ./platforms/ios/cordova/clean$ sudo ionic plug remove cordova-plugin-network-information$ sudo ionic plugin add https://github.com/apache/cordova-plugin-network-information$ sudo ionic build ios
推荐答案
当你添加一些插件时，ios build开始失败没有明显的原因。大部分时间这与插件无关。
When you add some plugins , ios build start failing for no apparent reason. Most of the time this is nothing to do with the plugin.
删除平台并将其重新添加回来对我来说一直都很有效。
Removing the platform and adding it back again worked for me all the time.
尝试删除并再次添加平台
try removing and adding the platform(s) again
离子平台删除ios
离子平台添加ios
