我安装了flutter,但出现了一些错误。我知道很多解决此错误的方法,但是它们对我来说不是解决方法。我该如何解决这个问题?
我的JAVA_HOME位于C:\ Program Files \ Java \ jdk-13.0.2
C:\Users\Flamador>flutter doctor --android-licenses
A newer version of the Android SDK is required. To update, run:
C:\Users\Flamador\AppData\Local\Android\Sdk\tools\bin\sdkmanager --update
C:\Users\Flamador>C:\Users\Flamador\AppData\Local\Android\Sdk\tools\bin\sdkmanager
--update

ı尝试此命令,但是...
set JAVA_OPTS=-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee
再次
C:\Users\Flamador>C:\Users\Flamador\AppData\Local\Android\Sdk\tools\bin\sdkmanager --update
Error occurred during initialization of boot layer
java.lang.module.FindException: Module java.se.ee not found
并非默认情况下,JDK 13中并非所有模块都可用。要解决您的问题,如果将JAVA_HOME
设置为JDK 1.8并运行update命令,则要容易得多。
