错误运行子进程cordova时发生错误

Question

我已经完成了一个项目，我想构建一个apk。我已经尝试构建它，但是在编写构建它的句子之后，第三个代码给了我一个错误。这里我写的代码或语句来构建它。

ionic cordova platform remove android
ionic cordova plarform add android@6.4.0
ionic cordova build android

3 天前，我按照上面编写的代码构建了一个项目。这里的错误。（这次我连接了firebase）

Platform android already added.
[ERROR] An error occurred while running subprocess cordova.

        cordova platform add android@6.4.0 --save exited with exit code 1.

        Re-running this command with the --verbose flag may provide more information.

E:\ionic\notasFirebase>ionic cordova build android

> cordova build android
Unable to load PlatformApi from platform. Error: Cannot find module 'E:\ionic\notasFirebase\platforms\android\cordova\Api.js'
Unhandled error. (The platform "android" does not appear to be a valid cordova platform. It is missing API.js. android not supported.)

Answer 1

请试试这个命令，它在我的项目中工作。

npm i cordova-res

Answer 2

我遇到了这个错误，我重新安装了Cordova：

npm uninstall -g cordova
npm install -g cordova

这对我来说很有效。此错误还有其他原因，因此我不确定这对您是否有效。
