【中文标题】Flutter - FAILURE：构建失败并出现异常。 - 无法启动守护进程。 - 安卓工作室 - VSCode

【英文标题】：Flutter - FAILURE: Build failed with an exception. - Unable to start the daemon process. - Android Studio - VSCode

【发布时间】：2021-06-23 03:29:09

【问题描述】：

每当我尝试使用 flutter run -v 运行 Flutter 应用程序时，都会出现以下错误。如果我不使用终端，只需单击运行，正在运行的 gradle 任务会继续运行，并且没有任何反应。

我试过了：

已更改 gradle.properties org.gradle.jvmargs=-Xmx1536m => org.gradle.jvmargs:-Xmx1024m 已删除 .gradle 文件 重置我的笔记本电脑

我能做什么？

颤动运行-v

【问题讨论】：

您的计算机内存不足。我建议切换到 vscode 并将你的内存升级到至少 8gb

@Uni，我的内存 8gb（7.71gb 可用），对于 vscode，它会发出警报，此窗口不再响应颤动运行

这很奇怪。你能发布flutter run --verbose的输出吗？

【参考方案1】：

问题是 OpenJDK 平台二进制文件会打开许多​​实例，这会占用我的内存， 我从这个question 和this answer 中发现了这个问题，说要关闭热点并且确实有效。 在某些情况下，重新启动您的笔记本电脑也可能有效，但并非全部。

我不知道 Hotspot 是怎么出问题的，或者它以什么方式连接到 OpenJDK，如果有人有解释，请发表评论。

【参考方案2】：

请始终以文本而不是图像的形式发布您的错误日志。

1- 运行 flutter clean 然后再次构建。

2- 你是在模拟器还是物理设备上运行它？

3- 如果在模拟器上，增加该设备的虚拟内存。更好的是，删除模拟器并创建一个新的。

4- 如果还是不行，运行flutter upgrade。

5- 您可以将文件构建为 APK 吗？换句话说，不在设备上运行？

6- 请发布flutter build apk -v的输出。

【讨论】：

我在物理设备上运行它

这可能意味着您的设备内存不足。请发布flutter build apk -v 的输出，我们可以查看您的应用程序是否构建，排除这是您的计算机问题或配置与模拟器\手机问题。

我添加了flutter build apk -v输出

@salma.m 这显然是计算机问题，有些东西正在占用您的内存。尝试重新启动计算机，关闭所有内容并打开代码，然后尝试构建它。您使用的是什么操作系统？

我使用的是 Windows 10。
