php - 如何从任何地方运行 Composer ？

Question

我刚刚在我的 /usr/bin 文件夹中安装了 composer，所以当我从那个文件夹运行 php composer.phar 时，我会得到关于 composer 的帮助信息。但是，当我尝试从其他文件夹运行相同的文件时，我得到 Could not open input file:composer.phar。

如何毫无问题地从任何地方调用php composer.phar？

Answer 1

您可以调用global installation (archived guide):

Since Composer works with the current working directory it is possible to install it in a system-wide way.

1. Change into a directory in your path like cd /usr/local/bin
2. Get Composer curl -sS https://getcomposer.org/installer | php
3. Make the phar executable chmod a+x composer.phar
4. Change into a project directory cd /path/to/my/project
5. Use Composer as you normally would composer.phar install
6. Optionally you can rename the composer.phar to composer to make it easier

更新:有时您不能或不想在 /usr/local/bin 下载(有些遇到用户权限问题或访问受限)，在这种情况下，你可以试试这个

1. 打开终端
2. curl -sS http://getcomposer.org/installer | php -- --filename=composer
3. chmod a+x Composer
4. sudo mv composer/usr/local/bin/composer

更新 2:对于 Windows 10 和 PHP 7，我推荐 this tutorial (archived)。就我个人而言，我安装了 Visual C++ Redistributable for Visual Studio 2017 x64 PHP 7.3 VC15 x64 Non Thread Safe 版本之前(在 PHP for Windows 页面，侧边菜单中检查两者的哪个版本)。仔细阅读，可能启用扩展部分可能会有所不同(extension=curl 而不是 extension=php_curl.dll)。像魅力一样工作，祝你好运!
