React Native：Java 堆空间

Question

我目前正在使用 React Native 构建我的 Android APK，遵循 doc。

我收到此错误：

./gradlew bundleRelease

当我运行时

./gradlew signingReport

一切都很好：

这是我的

android/gradle.properties

android.useAndroidX=true

android.enableJetifier=true

FLIPPER_VERSION=0.93.0

MYAPP_UPLOAD_STORE_FILE=my-upload-key.keystore
MYAPP_UPLOAD_KEY_ALIAS=my-key-alias
MYAPP_UPLOAD_STORE_PASSWORD=computer
MYAPP_UPLOAD_KEY_PASSWORD=computer

我在这篇文章中找不到解决此问题的方法：

• React Native 任务：app:validateSigningDebug 失败

我的

debug.keystore

也使用官方模板：https://raw.githubusercontent.com/facebook/react-native/master/template/android/app/debug.keystore

如何解决这个问题？

Answer 1

即使您在签名步骤中遇到错误，似乎与此无关，而只是 java 内存不足。

尝试将以下行添加到 gradle.properties 中以增加 Java 堆大小。

org.gradle.jvmargs=-Xmx2g -XX\:MaxHeapSize\=4g

Answer 2

有同样的问题，我的电脑有54GB内存，运行进程时有22GB可用空间。
