我在 Ubuntu 22.03.1 上。我想使用 Oracle Developer Studio 作为 Fortran IDE。
我从以下网址下载了 OracleDeveloperStudio12.6-linux-x86-rpm.tar.bz2这里，解压它，并尝试执行它的安装脚本
sudo ./developerstudio.sh
终端返回：
Configuring the installer...
Searching for JVM on the system...
Java installation was not found on this computer
Java 1.5.0_03 or later is required for installing Oracle Developer Studio. Make sure that Java is properly installed and run installer again.
You can specify valid Java location using --javahome installer argument.
To download Java installation bundle (JDK or JRE), visit http://www.oracle.com/technetwork/java/javase/downloads/index.html
因此我继续安装 JDK。我jdk-18_linux-x64_bin.deb从链接下载。尝试使用终端安装和配置并sudo ./developerstudio.sh再次运行命令，它给出了相同的错误。然后我卸载了 JDK 并使用 GUI 重新安装，仍然是相同的错误。然后我安装了apt-getjdk 包，仍然是相同的错误。
我相信我的 Java 已经安装好了：

我也在~/.bashrc中导出了它的路径，但仍然存在同样的问题。
export PATH="/usr/lib/jvm/java-11-openjdk-amd64/bin:$PATH"
