我已按照说明进行操作@https://github.com/tools/godep关于更新依赖项,但是当我使用更改后的版本进行构建\安装时,它尚未在Godeps/_workspace/pkg中更新所以我有gogetgithub.com/golang/gloggodepsavegodepgoinstall我看到了Godeps/_workspace/pkg/linux_amd64/github.com/golang/glog.a中的修改时间戳Godeps/Godeps.json中的rev提交值但现在当我想更新时,我会按照说明进行操作gogetgithub.com/golang/gloggo

如何使用特定导入的版本标签一次获取Go包的所有依赖项?假设我有一个包含多个包的go树:src/foo/bar/(gocodeinpackagebar)x.goquux/(gocodeinpackagemain)y.go现在让包`bar'依赖于使用标签版本的第三方库(即通常获取:goget-tagsmylib_2.0github.com/user/mylib)我想做的是在导入行指定一个标签以便我的树上的goget./...获得正确的版本方案。像这样的东西:import"github.com/user/mylib"`tags=mylib_2.0` 最佳答案
