golang项目包管理-glide使用简介

介绍

项目源码 ：https://github.com/Masterminds/glide

glide.yaml

官方文档 ：https://glide.sh/docs/glide.yaml

安装

go get -v github.com/Masterminds/glide
go install github.com/Masterminds/glide

初始化

• 如果是未使用 glide 的工程直接

glide init

在初始化过程中， glide 会询问一些问题
一般建议 y,在升级策略是建议 只下载补丁(patch)不下载升级(minor)
完成后会生成文件 glide.yaml

glide.yaml记载了依赖包的列表及其更新规则

注意这个文件必须 utf-8 编码

glide 版本规则

=: equal (aliased to no operator)
!=: not equal
>: greater than
<: less than
>=: greater than or equal to
<=: less than or equal to
1.2 - 1.4.5 which is equivalent to >= 1.2, <= 1.4.5
2.3.4 - 4.5 which is equivalent to >= 2.3.4, <= 4.5
1.2.x is equivalent to >= 1.2.0, < 1.3.0
>= 1.2.x is equivalent to >= 1.2.0
<= 2.x is equivalent to < 3
* is equivalent to >= 0.0.0
~1.2.3 is equivalent to >= 1.2.3, < 1.3.0
~1 is equivalent to >= 1, < 2
~2.3 is equivalent to >= 2.3, < 2.4
~1.2.x is equivalent to >= 1.2.0, < 1.3.0
~1.x is equivalent to >= 1, < 2
^1.2.3 is equivalent to >= 1.2.3, < 2.0.0
^1.2.x is equivalent to >= 1.2.0, < 2.0.0
^2.3 is equivalent to >= 2.3, < 3
^2.x is equivalent to >= 2.0.0, < 3

安装依赖

如果是已经使用 gilde 管理的工程，本身包含 glide.yaml 文件

glide install

安装后会生产文件 glide.lock
这个文件记载了依赖包确定的revision, 下次再执行 glide install 时，会直接读这个文件下载确定的版本

升级依赖

glide up 会按照语义化版本规则更新依赖包代码

编辑文件 glide.yaml 然后执行

glide up

获取依赖

glide get github.com/orcaman/concurrent-ma

使用镜像

可以通过配置将墙了的版本库 URL 映射到没被墙的 URL，甚至也可以映射到本地版本库

glide mirror set golang.org/x/crypto github.com/golang/crypto
glide mirror set golang.org/x/sys github.com/golang/sys

这样就将这个库从当前工程的

- package: golang.org/x/crypto

修改结果 $HOME/.glide/mirrors.yaml

repos:
- original: golang.org/x/crypto
  repo: github.com/golang/crypto

类似的

glide mirror set golang.org/x/text /home/users/qiangmzsx/var/golang/golang.org/x/text

移除镜像

glide mirror remove golang.org/x/crypto

全局配置

GLIDE_HOME变量，
该变量就是$HOME/.glide

这个目录之前有提到过，除了包含有mirrors.yaml还有一个很重要的目录cache本地 cache
每次更新代码时，glide 都会在本地保存 cache，以备下次 glide install 使用

GLIDE_HOME可以通过如下命令修改

glide --home [path]

问题

镜像功能有时候不好用，可以用 gopm 安装到全局来解决

Error scanning golang.org/x/sys/unix: cannot find package

[WARN]    Unable to checkout golang.org/x/sys/unix

• fix
