在使用 GoLand/IntelliJ IDEA 调试 Go 程序时，因 Go 版本升级到 1.25.0 而 Delve 调试器版本过旧，导致无法监听断点并抛出版本不兼容警告。解决方案是通过 go get -u 拉取最新版 Delve，手动编译安装后替换 IDE 内置的调试器二进制文件。

解决方案（mac当前 & windows同理）

前提 GOPATH 一定是配置好了的

shell
# 拉最新的依赖
tianjun@iodboy agentrun-gateway % go get -u github.com/go-delve/delve
go: added github.com/go-delve/delve v1.26.1

# 上一步的版本是 v1.26.1，所以要到下面这个路径去，其他版本的自己替换一下，都明白怎么做吧
tianjun@iodboy agentrun-gateway % cd $GOPATH/pkg/mod/github.com/go-delve/delve@v1.26.1/cmd/dlv

# 构建安装 v1.26.1 版本的 delve。没报错即可
tianjun@iodboy dlv % go install

# 替换旧的dlv，后面那一大串路径，麻烦各位到你们自己的异常信息里面找找
tianjun@iodboy dlv % cp "$GOPATH/bin/dlv" "/Users/tianjun/Library/Application Support/JetBrains/IntelliJIdea2024.1/plugins/go-plugin/lib/dlv/macarm/dlv"

IDEA打上断点，重新调试项目
