但是我手动调用 git clone那几个地址都是可以clone的

经过翻看composer在github的issues，查到一个解决办法，因为我是从symfony官网下载的带vendor的2.1.4版本，然后解压之后就执行了 composer update 但是遇到了这个错误，github上回复说：

justin-amt commented 4 months ago

I have exactly same problem on php composer.phar update

[RuntimeException]
Failed to clone http://github.com/fabpot/Twig.git via git, https and http protocols, aborting.

- git://github.com/fabpot/Twig.git
fatal: No such remote 'composer'

- https://github.com/fabpot/Twig.git
fatal: No such remote 'composer'

- http://github.com/fabpot/Twig.git
fatal: No such remote 'composer'

How to correct it?

Seldaek commented 4 months ago
@justinamt that looks like you have an outdated vendor dir (from a very old composer.phar) just delete the vendor/* and run install or update again to get them up to date.

from https://github.com/composer/composer/...

于是我mv了vendor文件夹，然后执行 composer install 发现可以正常下载了。

如果你手工删除过包并自己手动clone，之后再用 composer update 命令来更新的话，也是会报这样的错误的。

在运行 composer update 命令的时候添加 -vvv 参数，可以看到更详细的输出结果，如:

  - Installing xxx/xxx (dev-master f53e70e)
    Cloning f53e70e2d62fbf6f83916f7aff0ea735978f8634
Executing command (CWD): git clone --no-checkout 'http://xxx.com/namespace/xxx.git' '/Users/david/Work/git/project/xxx.com/vendor/namespace/xxx' && cd '/Users/david/Work/git/project/xxx.com/vendor/namespace/xxx' && git remote add composer 'http://xxx.com/namespace/xxx.git' && git fetch composer
Executing command (/Users/david/Work/git/project/xxx.com/vendor/namespace/xxx): git branch -r
Executing command (/Users/david/Work/git/project/xxx.com/vendor/namespace/xxx): git checkout 'master'
Executing command (/Users/david/Work/git/project/xxx.com/vendor/namespace/xxx): git reset --hard 'f53e70e2d62fbf6f83916f7aff0ea735978f8634'

可以看到，composer 会再设置一个远程管理仓库，如果是自己手工 clone，那么就会少了这一步操作，当然会报错了，所以，若是要自己手工 clone 某个仓库的代码， clone 后进入代码目录，多加一步操作即可：

git remote add composer ${repo_url}
