我看着下面，沒有什麼幫助：How to deal with "java.lang.OutOfMemoryError: Java heap space" error (64MB heap size)IntelliJ IDEA的無法啓動
昨天的IntelliJ IDEA是工作正常。今天當我啓動程序時，會發生以下情況：
[email protected]:~/dev/java$ /opt/idea-IC-162.2032.8/bin/idea.sh

顯然我內存不足。我知道我不是：

我也試過以下/opt/idea-IC-162.2032.8/bin/idea.sh -Xms512m，得到了錯誤：

我運行64位，所以我創建的文件~/.IdeaIC2016.2/idea64.vmoptions與內容：
-Xms1024m
-Xmx1024m
仍然不起作用。
就像Eclipse一樣，是否有一種.ini文件，您可以在其中爲您的JVM添加一些參數？也許這只是IntelliJ的過程需要更多的內存，而不是你的電腦上沒有剩下任何東西。 – MadJlzz
@MadJlzz我嘗試追加將參數-Xms512m添加到命令（我更新了問題）。我會看看.ini文件。 –
檢查可以爲JVM添加參數的文件。很確定這會在你增加Intellij的JVM堆後解決你的問題。 – MadJlzz
