当我打开 intellij idea 时，Java 崩溃了

Question

打开 Intellij Idea 时经常崩溃。

我尝试过不同的 Intellij Idea 版本(2019.1、2018.3)。

我安装了 Oracle JDK(Java SE 开发工具包 8u201)。

我的操作系统:macOs Mojave。

这是崩溃日志的一部分: (在这里分享所有日志太长了。查看所有日志:这里paste bin)

我找不到原因。有人可以帮助我吗？

Answer 1

Intellij默认运行在OpenJDK上，你的问题原因可能是intellij使用的OpenJDK版本和Oracle JDK有冲突。我的想法是把intellij默认的JDK改成Oracle JDK。并且在intellij官网找到了步骤。

• 首先，启动您的 intellij 并忽略 Java 崩溃。
• 其次，按 Ctrl + Shift + A 并键入 Switch Boot JDK。
• 第三，双击“Switch Boot JDK”项目栏并选择您的Oracle JDK安装目录。
• 最后，重新启动您的 intellij。
