尝试安装symfony 2 composer时出错

Question

在配置文件app/config/parameters.yml NEXT之后抛出错误，我该如何修复？

通过作曲家安装symfony：

Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-install-cmd event terminated with an exception

[RuntimeException]                                                         

An error occurred when executing the "'cache:clear --no-warmup'" command.

如documentation中所述，您必须将@加倍@@来逃避parameters: # ... database_password : "@@admin1" ：

import string
alphalower = string.ascii_lowercase
alphaupper = string.ascii_uppercase
digs = string.digits

def checkio(data):
    if len(data) >= 10:
        if data.count(digs) >= 1:
            if data.count(alphaupper) >= 1:
                if data.count(alphalower) >= 1:
                    return True
    else:
        return False
