golang + Godeps : Adding new dependency override Godeps. json文件

Question

我正在使用 Godeps 将我的依赖项保存到我的 go 项目中。

现在我的 Godeps.json 文件如下所示:

{
    "ImportPath": "github.com/some/repo",
    "GoVersion": "go1.6",
    "GodepVersion": "v74",

    ],

如果我想使用 go get 安装一个新的依赖:

去获取“github.com/robfig/cron”

这将覆盖我的 Godeps.json 文件，它只会存储我安装的最新包，而且还会从我的 vendor 文件夹中删除包。

如何添加而不是替换此依赖项？

Answer 1

如果您不运行 godeps save，那么新的依赖项将不会保存在您的 Godeps.json 中。很难想象为什么你会想要同一个库的两个版本，但如果你真的想这样做，那么在你的项目部署期间，首先执行 godep restore 然后安装你的依赖项 go get "github.com/robfig/cron"。这将防止替换
