当我尝试通过Java驱动程序连接neo4j时，出现错误“Neo4j无法启动，因为数据库文件需要升级，而升级在配置中被禁用。请在配置文件中将”dbms.allow_upgrade "设置为“true””。尽管我在neo4j.conf文件中将属性dbms.allow_upgrade设置为true，但没有任何更改。
dbms.allow_upgrade
true
neo4j.conf

这对我很有效，升级到3.3.1 neo4j Docker镜像！我尝试了以下方法，但这对3.0也不起作用：

在我的例子中，问题是配置文件不是我所想的那个。根据this documentation，它应该在<neo4j-home>/conf/neo4j.conf以下但是，运行neo4j stop，然后运行neo4j start，会打印出几个密钥路径。Directories in use: home: /var/lib/neo4j config: /etc/neo4j logs: /var/log/neo4j plugins: /var/lib/neo4j/plugins import: /var/lib/neo4j/import data: /var/lib/neo4j/data certificates: /var/lib/neo4j/certificates run: /var/run/neo4j因此，编辑在/etc/neo4j下找到的配置工作正常。
<neo4j-home>/conf/neo4j.conf
neo4j stop
neo4j start
