macos – Flyway ERROR：无法在Mac Sierra 10.13上加载

2023年3月25日 252次阅读

我使用brew安装了flyway,我正在尝试为postgres运行迁移,我收到此错误：

Boxfuse的Flyway 4.2.0

错误：无法加载/usr/local/Cellar/flyway/4.2.0/libexec/drivers/postgresql-9.4.1208.jre6.jar

我检查了这条路径,目录和文件存在.

有什么建议 ？

最佳答案 这是使用版本5.x解决的Flyway 4.x的已知问题(
1545)

解决方案：安装5.x版本 – 我向Homebrew提交了pull request以更新公式

根本原因是ClassCastException – 与Java 9更改相关(issue 3).

使用-X标志运行以查看显示真正的问题：

$flyway info -X
