尝试启动Grakn但出现Java错误

Question

我正在尝试在控制台中以./grakn server start来启动Grakn。我在grakn目录中，但出现以下错误：

An error has occurred during boot-up. Please run 'grakn server status' or check the logs located under the 'logs' directory.
Unsupported Java version [11] found. Grakn needs Java 1.8 in order to run.

Answer 1

Grakn使用Java 8，而您使用Java11。可以通过安装Java 8的JDK来解决此问题，您应该能够在系统Moment parse string+format上找到它。

然后，您需要确保可以找到Java 8。在mac / unix上：

export JAVA_HOME=`/usr/libexec/java_home -v 1.8
