golang + Godeps:添加新的依赖项覆盖Godeps.json文件

Question

我正在使用Godeps来保存我的go项目的依赖项。

现在，我的Godeps.json文件如下所示：

{
    "ImportPath": "github.com/some/repo",
    "GoVersion": "go1.6",
    "GodepVersion": "v74",
    "Packages": [
        "gopkg.in/mgo.v2",
        "github.com/sendgrid/sendgrid-go",

    ],
    "Deps": [

如果我想使用go get安装一个新的依赖项：

go get "github.com/robfig/cron"

这将覆盖我的Godeps.json文件，它将只存储我安装的最新包，而且它将从我的vendor文件夹中删除这些包。

如何添加此依赖项而不是替换它？

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。虽然很难想象为什么你会想要同一个库的两个版本，但是如果你真的想这样做，那么在你的项目部署过程中，首先执行godep restore，然后安装你的依赖项，因为go get "github.com/robfig/cron".This会阻止替换
