java - 无法让 Stardog 在 Mac OS X 上运行

Question

我刚刚下载了 Stardog，并尝试在我的机器 (Mac OS X 10.14.2) 上运行它。

我使用 ZSH shell 并在我的 .zshrc 文件中添加了以下两行:

export STARDOG_HOME="/Applications/stardog-6.1.0"
export PATH="$PATH:$STARDOG_HOME/bin"

以下是我的整个 $PATH 变量:

➜  echo $PATH
/Users/my_user/.nvm/versions/node/v11.6.0/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Applications/stardog-6.1.0/bin

以下是我的java版本:

➜  java --version
openjdk 11.0.1 2018-10-16
OpenJDK Runtime Environment 18.9 (build 11.0.1+13)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode)

我在 /Applications/stardog-6.1.0 中复制了许可证，然后尝试运行stardog-admin server start 但这是输出:

我错过了什么？

Answer 1

documentation对于 Stardog(Stardog 6.1.0(2019 年 1 月 16 日))状态:

Requirements

It just doesn’t get any easier than this: Stardog runs on Java 8.

---

安装 Java 8。

我希望在适当的时候，Stardog 的供应商会发布一个适用于 Java 11 的版本，但我在他们的网站上看不到任何公告。 (有一个 Stardog 7.0.0 Beta ......但发行说明没有提到 Java 11。)
