Neo4j 无法启动，因为数据库文件需要升级并且配置中禁用了升级

Question

当我尝试通过其 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，并且配置中禁用了升级。请在配置文件中将' dbms.allow_upgrade' 设置为 ' '”。true

尽管我已在文件中将属性设置dbms.allow_upgrade为，但没有任何更改。trueneo4j.conf

Answer 1

这对我有用，升级到 3.3.1 neo4j Docker 镜像！我尝试了以下方法，但这对 3.0 不起作用：

 docker run \
  --publish=7474:7474 --publish=7687:7687 \
  --volume=$HOME/neo4j/data:/data \
  --volume=$HOME/neo4j/logs:/logs \
  --env=NEO4J_dbms_allow_upgrade=true \
  --env=NEO4J_dbms_allow_format_migration=true \
  neo4j:3.0
