我正在使用Ionic2，我已经安装了Xcode。当我在我的离子项目目录中运行命令Cordova encountered an error.
You may get more insight by running the Cordova command above directly.
[ERROR] An error occurred while running cordova prepare (exit code 1):
You have been opted out of telemetry. To change this, run: cordova
telemetry on.
Using this version of Cordova with older version of cordova-android is
deprecated. Upgrade to cordova-android@5.0.0 or newer.
Error: Your android platform does not have Api.js
macbooks-mbp:canon macbookpro$ (node:839) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: channel closed
时，我收到此错误：
p1 {
display = none;
}
button {
position:absolute;
background-color: #8C6D09;
color: white;
padding: 16px 32px;
display:inline-block;
margin:4px 2px;
-webkit-transition-duration: 0.4s; /* Safari */
transition-duration: 0.4s;
}
button1{
background-color:#8C6D09;
color:#FFF;
position:absolute;
}
p1 {
display = none;
}我没有安装android studio也不是sdk，因为我想在ios模拟器中运行该项目。任何人都可以告诉我解决方案吗？
提前致谢。
