我正在我的Windows控制台中执行此操作：

php composer.json create-project test2

我刚刚得到上面的字符串，没有任何反应？如何正确运行composer.json来创建项目？

Answer 1

你必须下载作曲家：

curl -sS https://getcomposer.org/installer | php

要么

php -r "readfile('https://getcomposer.org/installer');" | php

如果你有composer.json文件，你应该运行：

composer.phar install

或者如果你想创建新项目

composer.phar create-project

Answer 2

当你的终端中已存在composer命令（例如，使用composer update测试）时，在具有composer.json的同一文件夹中使用composer --version。

Answer 3

我使用'composer install'并且它运行良好

composer install

要么

php composer install
