composer怎么查看已经安装的扩展包
composer查看已经安装的扩展包的方法:
我们有时候需要知道已经安装的包的名称和版本信息,会用到如下命令:
composer show -i
这个试composer show –installed的短命令;
查看全局安装的包名称和版本:
composer global show
我们不知道有哪些命令以及如何使用的时候,可以列出所有的命令,然后敲你不明白的命令,在后面加-h就可以查看相应的帮助信息:
查看所有composer命令:
composer -l
或者:composer
或者:composer list
然后就会出来很多命令,随便挑一个:
composer show -h
这个命令的意思是如何使用composer show ,-h是–help的缩写。
