1)首先，使用Composer下载Laravel安装程序:

编译器需要“laravel/installer”

2)确保将~/.composer/vendor/bin目录放在你的PATH中，这样laravel可执行文件就可以被你的系统定位。

  set PATH=%PATH%;%USERPROFILE%\AppData\Roaming\Composer\vendor\bin

  eg: “C:\Users\\AppData\Roaming\Composer\vendor\bin” 

3)安装后，简单的laravel new命令将在您指定的目录中创建一个新的laravel安装。

eG:  laravel new blog

如果你已经全局安装了Composer，你可以使用下面的命令安装Laravel安装工具:

composer global require "laravel/installer=~1.1"

MAC用户:

1. 打开终端

cd ~

2. 仔细检查$PATH

echo $PATH

3.编辑文件

nano ~/.bash_profile

4. 粘贴

export PATH="~/.composer/vendor/bin:$PATH"

别忘了加引号。

5. control + X (y + enter保存文件并退出)

现在开始vagrant，打开你的文件夹试试:

laravel new yourprojectname

如果你使用的是Ubuntu 16.04。

You need to find the composer config files in my case is : ~/.config/composer or in other cases ~/.composer/ you can see the dir after this command composer global require "laravel/installer" after Laravel Installed you can find your laravel in ~/.config/composer/vendor/laravel/installer/. and you will find the Laravel shortcut command in here : ~/.config/composer/vendor/bin/ set your .bashrc using nano ~/.bashrc and export your composer config file : export PATH="$PATH:$HOME/.config/composer/vendor/bin" or you can use allias. but above solution is recommended. alias laravel='~/.config/composer/vendor/laravel/installer/laravel' Now refresh your bashrc using source ~/.bashrc and then laravel is ready!!

以上步骤适用于我的Ubuntu 16.04

如果你是2021年来到这里，这也适用于我使用Ubuntu 16.04

nano ~/.bash_profile 
export PATH=$HOME/.config/composer/vendor/bin:$PATH
ctrl+x and save 
source ~/.bash_profile

我设置了PATH，但它不起作用。我会找到其他解决方法。(OSX 10.10 & laravel 5.2) 1)找到可执行文件:

~/.composer/vendor/laravel/installer/laravel 

2)给予执行权限:

chmod +x ~/.composer/vendor/laravel/installer/laravel 

3)软链接到/usr/bin:

sudo ln -s /Users/zhao/.composer/vendor/laravel/installer/laravel /usr/bin/laravel
