错误:无法获取平台cordova android@^6.2.3

Question

我遇到了这个问题：

allart@allart-vm-lubuntu:~/Documents/apps/MyApp/myapp$ ionic cordova platform add android 
> cordova platform add android --save
Using cordova-fetch for cordova-android@^6.2.3
Error: Failed to fetch platform cordova-android@^6.2.3
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.

已经尝试使用NPM缓存清洁，卸载和重新安装软件包和经理，重新启动，升级系统等。

这是我的规格：

$ node -v
v9.2.0
$ npm -v
3.10.10
$ ionic -v
3.18.0
$ cordova -v
7.1.0
Ubuntu 17.10 on a VM. 

有什么想法吗？预先感谢您。

Answer 1

检查主目录中是否有node_modules文件夹，如果可以删除，请访问https://github.com/nodejs/node/node/node/issues/9377#issuecomment-330234631。这修复了我在Macos上的。

做以下操作也对我有用，但每次都必须这样做

 rm -r node_modules/

Answer 2

无需删除整个node_modules文件夹。

只需删除node_modules文件夹中的以下文件夹：

• rm -R node_modules/cordova-android
• rm -R node_modules/ionic-angular

并删除package-lock.json：

• rm package-lock.json
