require可以更新
修改json文件也可以
我想知道是不是 update 包名不能指定版本呢
手冊(cè)上沒(méi)看到
謝謝諸位
其他回答都是什么啊。
版本約束直接加到后面就行了

Help:
The require command adds required packages to your composer.json and installs them.
If you do not specify a package, composer will prompt you to search for a package, and given results, provide a list of
matches to require.
If you do not specify a version constraint, composer will choose a suitable one based on the available package versions.
If you do not want to install the new dependencies immediately you can call it with --no-update
參數(shù)里面就提到使用foo/bar:1.0.0 or foo/bar=1.0.0 or "foo/bar 1.0.0"
