无法让 Stardog 在 Mac OS X 上运行

Question

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

\n\n

我使用ZSHshell，并在我的文件中添加了以下两行.zshrc：

\n\n

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

\n\n

以下是我的全部$PATH变量：

\n\n

\xe2\x9e\x9c  echo $PATH\n/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\n

\n\n

以下是我的java版本：

\n\n

\xe2\x9e\x9c  java --version\nopenjdk 11.0.1 2018-10-16\nOpenJDK Runtime Environment 18.9 (build 11.0.1+13)\nOpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode)\n

\n\n

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

\n\n

我缺少什么？

Answer 1

Stardog 的文档（Stardog 6.1.0（2019年1 月 16 日））指出：

要求

\n

它只是没有比这更简单的了：Stardog 在 Java 8 上运行。

\n

\n\n

安装 Java 8。

\n

我预计 Stardog 的供应商在时机成熟时会发布一个可在 Java 11 上运行的版本，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。）

\n\n

更新：Stardog 9.0已更新至Java 11；请参阅发行说明。系统要求页面目前显示仅支持 Java 11。

\n

要点是……检查 Stardog 文档以了解您尝试使用的版本。
