当我想添加android plaform时，我遇到了这个错误
F:\OLLE\olle>cordova platform add android
Using cordova-fetch for cordova-android@7.0.0
(node:15100) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): CordovaError: Failed to fetch platform cordova-android@7.0.0
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.

首先，这个命令运行良好。我删除了android平台后，当我试图重新添加android平台时出错了。有没有人知道如何解决它？
答案 0 :(得分：1)
在rm nodemoduls之后删除Android文件夹并再次添加它是否无效然后创建新项目并粘贴src文件夹并在该工作正常后添加所有插件。

我同意@Praveen，我会这样做：
ionic cordova platform rm android
rm -rf node_modules
ionic cordova platform add android
还记得使用带有离子的cordova命令。它可能会使这个过程更加完整。
同时检查您对项目所在文件夹的权限，但可能会在cordova修复之前添加离子。
