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.

[ERROR] Exception:

已尝试使用npm cache clean，卸载并重新安装软件包和管理器，重新启动，升级系统等。

以下是我的规格：

$ node -v

$ npm -v

$ ionic -v
3.18.0

$ cordova -v
7.1.0

Ubuntu 17.10 on a VM.

有什么想法吗？提前谢谢。

Answer 1

检查主目录中是否有node_modules文件夹，若是，请将其删除，请参阅https://github.com/nodejs/node/issues/9377#issuecomment-330234631。这在MacOS上为我修复了它。

执行以下操作对我也有用，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

错误：无法获取平台cordova-android@^6.2.3
