如何使用composer在分支中安装最新版本？
[英]how to install the latest version in a branch with composer?
问题描述
Say I'm trying to install a package that has a 1.0 branch and a master branch. 
假设我正在尝试安装具有1.0分支和master分支的软件包。 The 1.0 branch has tags like 1.0.1, 1.0.2, etc. 1.0分支具有1.0.1、1.0.2等标签。
What I want to be able to do is to install the latest version in the branch. 我想要做的是在分支中安装最新版本。 I don't want to install a tagged release - I want to install the latest branch version. 我不想安装带标签的发行版-我想安装最新的分支版本。
Here's what I tried: 这是我尝试过的：
composer require package/package:1.0
composer require package/package:~1.0
Both of those got the most recent 1.0.* tag but not the latest in the 1.0 branch. 两者都获得了最新的1.0。*标记，但没有获得1.0分支中的最新标记。
Is what I'm trying to do even possible? 我要做什么甚至有可能吗？
For that matter what even is the difference between 1.0 and ~1.0 ? 就此而言， 1.0和~1.0之间的差异到底是什么？

You can require dev-master as the version name (or dev-branchName), and it will pull in the most recent commit from the specified branch. 您可以要求dev-master作为版本名称（或dev-branchName），它将从指定分支中提取最新提交。 For versioned branch names, use eg 2.0.x-dev as the version name instead. 对于版本化的分支名称，请使用例如2.0.x-dev作为版本名称。
(More details are available on the Schema - package links section of the Composer documentation.) （有关更多详细信息，请参阅Composer文档的“ 架构-程序包链接”部分。）
The difference between 1.0 and ~1.0 is that 1.0 specifies a specific version number, and ~1.0 specifies that any version "compatible" (according to semantic versioning) with 1.0 is allowed. 1.0和~1.0之间的区别是1.0指定了特定的版本号，而~1.0指定了允许任何与~1.0 “兼容”（根据语义版本控制）的版本。 From the Composer documentation : 从Composer文档中 ：
The ~ operator is best explained by example:
~1.2is equivalent to>=1.2 <2.0.0, while~1.2.3is equivalent to>=1.2.3 <1.3.0.~1.2等于>=1.2 <2.0.0，而~1.2.3等于>=1.2.3 <1.3.0。
There is also the similar ^ operator: ^1.2.3 is equivalent to >=1.2.3 <2.0.0 . 还有一个类似的^运算符： ^1.2.3等于>=1.2.3 <2.0.0 。
