我正在尝试构建一个 IONIC 项目，但我面临这个异常，我无法为此调试解决方案。我尝试了很多建议，但没有解决方案。我正在等待您的帮助

    1-ionic start test4 tabs
    2-cd test4
    3-ionic platform add android
    4-ionic build android

       Starting a new Gradle Daemon for this build (subsequent builds will be faster).



     FAILURE: Build failed with an exception.

     * What went wrong:
     Unable to start the daemon process.
     This problem might be caused by incorrect configuration of the daemon.
     For example, an unrecognized jvm option is used.
     Please refer to the user guide chapter on the daemon at https://docs.gradle.org/2.14.1/userguide/gradle_daemon.html

Answer 1

我假设您正在使用 Windows 查看堆栈跟踪。

请注意堆栈跟踪中的此消息：

Error occurred during initialization of VM
Could not reserve enough space for 2097152KB object heap

这通常发生在您拥有 32 位 JVM 时。如果您的操作系统是 64 位，请将 32 位 JVM 替换为 64 位 JVM。它具有更高的堆约束，将解决问题。这是推荐的解决方案。

阅读此oracle 文档以获取更多信息。

如果您的操作系统是 32 位，请尝试按以下方式设置您的操作系统并重新ionic build android发出命令（可能需要重新启动命令提示符）：

转到Start→ Control Panel→ System→ Advanced System Settings→ Advanced (tab)→ Environment Variables→ System Variables→ New：

Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M
