导读：在composer包中,我有post-install-cmd脚本,如下所示： #!/bin/bashecho 'Hello!'read -p 'Database password: ' DB_PASSphp setup/index.php database_password=$DB_PASSecho 'Complete!' 但是在composer安装后我遇到了这个错误： ...Generating autoload fi

在composer包中,我有post-install-cmd脚本,如下所示：

#!/bin/bash
echo 'Hello!'
read -p 'Database password: ' DB_PASS
php setup/index.php database_password=$DB_PASS
echo 'Complete!'

但是在composer安装后我遇到了这个错误：

...

我如何在作曲家脚本中询问用户输入？

解决方法

好的,您正在尝试执行bash / shell脚本来读取字符串并将其传递给您的php文件.我不确定,为什么这样做不成功.

另一种方法是留在post-install-cmd的PHP代码中.
这是一个事件,它可以访问Composer和IO.
要使用Console,您需要Composer中的$io对象.
您可以使用getIO()获取它.

然后,您可以使用方法ask()或askConfirmation()以交互方式询问用户“缺失”值.

非常简短：

$io = $this->getIO();
$pw = $io->ask('Enter your Password: ');

exec('php setup/index.php database_password=' . escapeshellarg($pw));
