尝试更新我的Intellij时出现OutOfMemory错误 [英] Getting a OutOfMemory error when attempting to update my Intellij

问题描述

我正在尝试将IntelliJ IDEA从build 141.177更新为141.178。
当更新下载所需的所有文件并开始更新时，我收到此错误：

I am trying to update IntelliJ IDEA from build 141.177 to 141.178. When the updated downloads all the files needed, and starts the update, I get this error:

Temp. directory: /tmp

java.lang.OutOfMemoryError: Java heap space

/ tmp 文件夹应位于我的根分区上，其大小为20GiB，目前仍然剩下大约8GiB。所以我真的不明白现在的问题是什么。另外我不确定RAM部分，我的系统在更新时使用了40％的RAM。

The /tmp folder should be on my root partition which has 20GiB of size, and currently it still has about 8GiB left. So I don't really understand what the problem could be here right now. Plus I am not sure about the RAM part, my system is using 40% of my RAM when I do the update.

推荐答案

阅读JetBrains 文档&有关如何增加IntelliJ的最大堆大小的此答案。

Read the JetBrains documentation & this answer about how to increase the maximum heap size for IntelliJ.

在 idea.vmoptions （32位版本）或 idea64中设置 -Xmx2048m 。 vmoptions （64位版本），并根据我上面提到的文档将其复制到适当的位置。

Set -Xmx2048m in idea.vmoptions (32-bit edition) or idea64.vmoptions (64-bit edition), and copy it to the appropriate location, according to the documentation I referred to above.

我也会执行文件>无效缓存/重新启动>无效并重新启动，只是为了确保所做的更改（可能没有必要，但以防万一）。

I would also do File > Invalidate Caches / Restart > Invalidate and Restart, just to be sure that the changes took (probably not necessary, but just in case).

我收到的完全相同在尝试通过自动更新程序从14.1.1升级到14.1.2时，今天堆栈跟踪。在OS X上，我通过将〜/ Library / Preferences / IdeaIC14 / idea.vmoptions 重命名为 idea64.vmoptions 来解决此问题。 。我已经在该文件中设置了 -Xmx2048m ，但显然在我正确重命名之前它没有被读取。

I received the exact same stack trace today while attempting to upgrade from 14.1.1 to 14.1.2 via the automatic updater. On OS X, I solved it by renaming ~/Library/Preferences/IdeaIC14/idea.vmoptions to idea64.vmoptions. I already had -Xmx2048m set in that file, but apparently it wasn't being read until I renamed it correctly.
