[英]Neo4j not starting on Raspberry Pi (memory issues and java.lang.NoClassDefFoundError)
I am currently trying to install Neo4j on my Raspberry Pi.我目前正在尝试在我的 Raspberry Pi 上安装 Neo4j。 The installation for the latest version worked great so far.到目前为止,最新版本的安装效果很好。 When I tried neo4j start
I received this error message but was able to resolve it by setting dbms.memory.heap.initial_size=12m
and dbms.memory.heap.max_size=12m
and dbms.memory.pagecache.size=1g
(allthough that feels wrong to me since my Pi has 8GB of memory): When I tried neo4j start
I received this error message but was able to resolve it by setting dbms.memory.heap.initial_size=12m
and dbms.memory.heap.max_size=12m
and dbms.memory.pagecache.size=1g
(allthough that我感觉不对,因为我的 Pi 有 8GB 内存):

Now , when I try to start neo4j I get this error in my logs:现在,当我尝试启动 neo4j 时,我的日志中出现此错误:
nohup: ignoring input

I have now been trying to google the problem for a couple hours but I feel like I don't really know what to look for.我现在一直在尝试用谷歌搜索这个问题几个小时,但我觉得我真的不知道要寻找什么。
My setup:我的设置:

)After some more trying it seems like it is a problem with the latest Neo4j version (4.2.3).经过更多尝试,最新的 Neo4j 版本(4.2.3)似乎有问题。 I now installed version 4.0.11 and it works without any problems.我现在安装了 4.0.11 版,它可以正常工作。
