Installing Composer globally for laravel usage?
提问by user3231419
I'm having some trouble with installing composer globally.
我在全局安装 Composer 时遇到了一些问题。
I install composer into my 'C:\wamp\bin\php\php5.4.12' - directory (I'm using WAMP) and make a project in 'C:\wamp\www\project' using the command: php composer.phar create-project.
我安装作曲家为我的'C：\ WAMP \ BIN \ PHP \ php5.4.12' -目录（我使用WAMP），并在项目'C：\ WAMP \ WWW \项目'使用下面的命令：php composer.phar create-project。
The problem is that I can only use the php composer.pharcommand when I'm in the directory where I installed it (bin\php\php5.4.12), this directory is already in my path variables.
问题是我只能php composer.phar在我安装它的目录（bin\php\php5.4.12）中使用该命令，这个目录已经在我的路径变量中了。
Their is also a composer.bath file including in that directory: "@ECHO OFF" "php '%~dp0composer.phar' %*"that should make it global but when I use the composer command in another directory (directory of my project) using cmd, a error pops up saying:
他们也是一个 composer.bath 文件，包括在该目录中："@ECHO OFF" "php '%~dp0composer.phar' %*"这应该使它成为全局文件，但是当我在另一个目录（我的项目目录）中使用 composer 命令时cmd，会弹出一个错误说：
"@ECHO OFF" "php 'C:\wamp\bin\php\php5.4.12\composer.phar... "
"@ECHO OFF" is not recognized as an internal or external command operable program or batch file.
"@ECHO OFF" "php 'C:\wamp\bin\php\php5.4.12\composer.phar..."
“@ECHO OFF”不是内部或外部命令可操作的程序或批处理文件。
Does anyone have a clue what the problem is?
有谁知道问题是什么？

Locate your `php.exe file, it is probably in:
找到你的 `php.exe 文件，它可能在：
C:\wamp\bin
or
C:\wamp\bin\php
Create a file (use notepad) composer.batin the same folder and add this line to it:
composer.bat在同一个文件夹中创建一个文件（使用记事本）并向其中添加以下行：
@php C:\wamp\bin\php\php5.4.12\composer.phar %*
Close and try to run composer from anywhere:
关闭并尝试从任何地方运行 composer：
cd\
composer --version

Although correct answer has been already posted, it is noteworthy to mention that there is a windows installer for composer https://getcomposer.org/Composer-Setup.exe
虽然已经发布了正确答案，但值得注意的是，这里有一个用于 Composer https://getcomposer.org/Composer-Setup.exe的 Windows 安装程序
You can install it just like any other exe file. During installation it will ask for path to php.exe. It is usually located at C:\wamp\bin\php\php{php-version}\php.exe
您可以像安装任何其他 exe 文件一样安装它。在安装过程中，它会询问 php.exe 的路径。它通常位于 C:\wamp\bin\php\php{php-version}\php.exe
Once installed you'll have to manually enable php_openssl, php_curl, php_socket by clicking on WAMP icon in the taskbar in bottom right. Then in PHP->PHP Extensions just click on the above three extensions to enable them.
安装后，您必须通过单击右下角任务栏中的 WAMP 图标手动启用 php_openssl、php_curl、php_socket。然后在 PHP->PHP Extensions 中点击以上三个扩展来启用它们。
You'll also have to enable openssl from all php.ini files by changing ;extension=php_openssl.dll to extension=php_openssl.dll i.e. uncommenting above line by removing ;
您还必须通过将 ;extension=php_openssl.dll 更改为 extension=php_openssl.dll 来启用所有 php.ini 文件中的 openssl，即通过删除 ;

As said hereopen command prompt in your windows machine, then execute the commands one by one or create a bat file and execute it. Mind your directory. Best option is :
正如这里所说，在你的windows机器上打开命令提示符，然后一一执行命令或创建一个bat文件并执行它。注意你的目录。最佳选择是：
cd C:\
mkdir ComposerSetup
cd ComposerSetup
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === 'e115a8dc7871f15d853148a7fbac7da27d6c0030b848d9b3dc09e2a0388afed865e6a3d6b3c0fad45c48e2b5fc1196ae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
Now create a batch file composer.bat and paste the line in it and save:
现在创建一个批处理文件 composer.bat 并将该行粘贴到其中并保存：
@php C:\ComposerSetup\composer.phar %*
Now add C:\ComposerSetup as your Path environment variable. Close the promot. Open a new command prompt and type composer --v. Basically you are running the composer.bat file from your prompt now.
现在添加 C:\ComposerSetup 作为您的 Path 环境变量。关闭促销。打开一个新的命令提示符并键入 composer --v。基本上，您现在正在从提示符运行 composer.bat 文件。
If you want to save the composer.phar and composer.bat file in other location, its okay, just change the directory location properly.
如果你想把 composer.phar 和 composer.bat 文件保存在其他位置，也可以，只要适当改变目录位置即可。
