Installing specific laravel version with composer create-project
提问by user1995781
The fastest and simplest way of installing Laravel is via composer command. From the laravel docs (http://laravel.com/docs/quick), it shows that we can install it with this:
安装 Laravel 最快最简单的方法是通过 composer 命令。从 laravel 文档（http://laravel.com/docs/quick），它表明我们可以通过以下方式安装它：
composer create-project laravel/laravel your-project-name --prefer-dist
But, when you run the above command, it will grab the latest version of Laravel. How can I control it if I want to install latest version of 4.0.x? Or, 4.1.x when 4.2 is out?
但是，当您运行上述命令时，它将获取最新版本的 Laravel。如果我想安装最新版本的 4.0.x，我该如何控制它？或者，当 4.2 出来时 4.1.x？

From the composer help create-projectcommand
从composer help create-project命令
The create-project command creates a new project from a given
package into a new directory. If executed without params and in a directory with a composer.json file it installs the packages for the current project.
You can use this command to bootstrap new projects or setup a clean
version-controlled installation for developers of your project.[version]
You can also specify the version with the package name using = or : as separator.
To install unstable packages, either specify the version you want, or use the --stability=dev (where dev can be one of RC, beta, alpha or dev).
create-project 命令从给定的
包创建一个新项目到一个新目录中。如果在没有 params 的情况下执行并且在包含 composer.json 文件的目录中执行，它将安装当前项目的包。
您可以使用此命令来引导新项目或
为项目的开发人员设置一个干净的版本控制安装。[version]
您还可以使用 = 或 : 作为分隔符指定带有包名称的版本。
要安装不稳定的软件包，请指定您想要的版本，或使用 --stability=dev（其中 dev 可以是 RC、beta、alpha 或 dev 之一）。
This command works:
此命令有效：
composer create-project laravel/laravel=4.1.27 your-project-name --prefer-dist
This works with the * notation.
这适用于 * 符号。

Have a look:
看一看：
Syntax (Via Composer):
语法（通过 Composer）：
composer create-project laravel/laravel {directory} 4.2 --prefer-dist
Example:
例子：
composer create-project laravel/laravel my_laravel_dir 4.2
Where 4.2 is your version of laravel.
其中 4.2 是您的 Laravel 版本。
Note: It will take the latest version of Laravel automatically If you will not provide any version.
注意：如果您不提供任何版本，它将自动采用最新版本的 Laravel。

Try via Composer Create-Project
通过 Composer Create-Project 尝试
You may also install Laravel by issuing the Composer create-project command in your terminal:
您还可以通过在终端中发出 Composer create-project 命令来安装 Laravel：
composer create-project laravel/laravel {directory} "5.0.*" --prefer-dist
回答by Toshi
composer create-project laravel/laravel=4.1.27 your-project-name --prefer-dist
And then you probably need to install all of vendor packages, so
然后你可能需要安装所有的供应商包，所以
composer install

To install specific version of laravel try this & simply command on terminal
要安装特定版本的 laravel 试试这个 & 简单的命令在终端
composer create-project --prefer-dist laravel/laravel:5.5.0 {dir-name}
回答by OlaJ
If you want to use a stable version of your preferred Laravel version of choice, use:
如果您想使用首选 Laravel 版本的稳定版本，请使用：
composer create-project --prefer-dist laravel/laravel project-name "5.5.*"
That will pick out the most recent or best update of version 5.5.* (5.5.28)
这将挑选出版本 5.5.* (5.5.28) 的最新或最佳更新
