IntelliJ IDEA 12.0 JVM Startup Error
提问by Philip Tenn
I just upgraded to IntelliJ IDEA 12.0and get an error immediately upon attempting to launch:
我刚刚升级到IntelliJ IDEA 12.0并在尝试启动时立即收到错误：
The JVM could not be started. The maximum heap size (-Xmx) might be too large or
an antivirus or firewall tool could block the execution.
I checked my idea.exe.vmoptionsfile and the maximum heap size is only 640m (I have 8 GB physical memory and am not running any other applications).
我检查了我的idea.exe.vmoptions文件，最大堆大小只有 640m（我有 8 GB 物理内存，没有运行任何其他应用程序）。
idea.exe.vmoptions
想法.exe.vmoptions
-Xms128m
-Xmx640m
-XX:MaxPermSize=640m
-XX:ReservedCodeCacheSize=64m
-XX:+UseCodeCacheFlushing
-ea
-Dsun.io.useCanonCaches=false
I still have IntelliJ IDEA 11.4on my machine and I am able to run that (using the same values for max heapsize in idea.exe.vmoptions). Since IntelliJ IDEA 11.4runs, I don't believe it is an antivirus or firewall issue. I have also checked those settings as well.
我仍然有IntelliJ IDEA 11.4我的机器上，我能够运行（使用相同的值，在最大堆大小idea.exe.vmoptions）。由于IntelliJ IDEA 11.4运行，我不认为这是防病毒或防火墙问题。我也检查了这些设置。
Anyone run across this or have any idea (no pun intended)?
任何人都遇到过这个或有任何想法（没有双关语）？

Assuming you are on windows I am curious why you are running the 32bit version of intellij when you have a 64bit machine?
假设你在 Windows 上，我很好奇你为什么在 64 位机器上运行 32 位版本的 intellij？
I was having the same error and found that there was two things going on. The first was that the link I had in the taskbar was pointing to the idea.exe instead of the idea64.exe, which meant I was only launching the 32bit version of intelliJ.
我遇到了同样的错误，发现发生了两件事。首先是我在任务栏中的链接指向idea.exe而不是idea64.exe，这意味着我只启动了32位版本的intelliJ。
Second there is another file for vm options for the 64bit. idea64.exe.vmoptions
其次，还有另一个 64 位 vm 选项文件。idea64.exe.vmoptions
After switching to the 64bit exe and making sure the vm options I wanted were correct in the vmoptions file I did not have any further issues.
切换到 64 位 exe 并确保我想要的 vm 选项在 vmoptions 文件中正确后，我没有任何进一步的问题。
On another interesting note I found that on 32bit machines when the 32bit version of intelliJ was set to have 1gb of memory for -Xmx and I had chrome open I would get the error. If I closed chrome I would no longer get the error. I think this had something to do with the jvm verifying that the required amount of memory was available before launching.
在另一个有趣的注意事项中，我发现在 32 位机器上，当 32 位版本的 intelliJ 设置为 -Xmx 的内存为 1gb 并且我打开了 chrome 时，我会收到错误消息。如果我关闭 chrome，我将不再收到错误消息。我认为这与 jvm 在启动之前验证所需的内存量是否可用有关。

Try to configure your idea to the default values
尝试将您的想法配置为默认值
-Xms128m
-Xmx512m
-XX:MaxPermSize=250m
-XX:ReservedCodeCacheSize=64m

-ea
-Dsun.io.useCanonCaches=false
VM options are loaded from the IDE_HOME\bin\[bits][.exe].vmoptions file.
VM 选项从 IDE_HOME\bin\[bits][.exe].vmoptions 文件加载。

I found that switching from a 32-bit version to a 64-bit version caused the issue, as my windows shortcuts still pointed to the old idea.exe and not the correct idea64.exe.
我发现从 32 位版本切换到 64 位版本导致了这个问题，因为我的 Windows 快捷方式仍然指向旧的 idea.exe 而不是正确的 idea64.exe。
