在谷歌搜索中，我试着这样做rm-R~/。作曲家/供应商/古兹http
但抛出一个错误，因为没有这样的目录
rm：无法删除'/home/lykos/。作曲家/供应商/guzzlehttp'：没有这样的文件或目录
我的~/。config/composer/composer。json文件如下所示
{
"require": {
"laravel/installer": "^1.5"
}
}
有没有办法解决这个问题？
泰勒在v1中修复了这个问题。0.3，但尚未对其进行标记，因此您可以安装dev master以获得更新版本：composer global require laravel/lumen安装程序：dev master
尝试删除全局~/。编写器目录。首先安装lumen/installer，然后安装laravel/installerglobal。对我来说很好。
laravel/lumen安装程序v1.0.0需要guzzlehttp/guzzlehttp~4.0|~5.0
guzzle的安装请求http/guzzle（锁定在6.3.0）
这意味着guzzlehttp/guzzlehttp被锁定在6.3.0，根据您的composer.lock文件，并且您的包（laravel/lumen-Inster）需要guzzlehttp/guzzle~4.0|~5.0。通过grep 6.3.0~/。作曲家/composer.lock命令检查它。
因此，您需要删除guzzlehttp/guzzlehttp从您的~/.作曲家/composer.json按照建议：
结论：删除guzzle http/guzzle6.3。0
否则，如果它不在那里，您需要删除依赖它的软件包，或者将laravel/lumen安装程序升级到v1。0.3（如前所述）。例如。
composer global require laravel/lumen-installer:^1.0.3
要查看依赖树（什么是使用不同版本的guzzer），您可以运行：
composer global show -t
