如何修复 Drush 8 / PHP 7.2 警告“count(): Parameter must be an array...”

Question

我在 Ubuntu 16.04 上运行 LAMP。我安装了 drupal 7，并且通过 Composer 1.5.2 版安装了 drush 8.1.3。我相信php7.2 中存在导致Github 上讨论的错误的错误，但是即使我应用了推荐的修复程序，即将 pear/console_table 更新到此处指示的最新版本，问题仍然存在。我还按照超级用户的说明进行操作，以确保我也安装了最新版本的 pear（未安装 PHPunit）。而且，仅供参考，根据此处找到的drush 安装文档，我也对我的.bashrc文件进行了适当的更改（如下）。

每当我运行时，drush status我都会收到以下错误：

count(): Parameter must be an array or an object that implements     [warning]
Countable Table.php:789
count(): Parameter must be an array or an object that implements     [warning]

如果我执行 drush sql-connect

Unable to load class Drush\Sql\Sql                                  [error]

#7 {main}

我的~/.bashrc文件内容如下：

export PATH="$HOME/.composer/vendor/bin:$PATH"

export PATH=/bin:/usr/local/bin:/usr/local/mysql/bin:$PATH

# Include Drush bash customizations.
if [ -f "/home/webdevusr/.drush/drush.bashrc" ] ; then
source /home/webdevusr/.drush/drush.bashrc
fi

# Include Drush completion.

if [ -f "/home/webdevusr/.drush/drush.complete.sh" ] ; then
source /home/webdevusr/.drush/drush.complete.sh
fi

# Include Drush prompt customizations.

if [ -f "/home/webdevusr/.drush/drush.prompt.sh" ] ; then
source /home/webdevusr/.drush/drush.prompt.sh
fi

drush cc all从我的 drupal 安装文件夹中执行的结果是：

No Drupal site found, only 'drush' cache was cleared. 

有人知道如何让 drush 为我的本地 (LAMP) Drupal 7 安装工作吗？

您可以编辑 .config/composer/vendor/pear/console_table/Table.php 或首先在系统中查找该文件。使用您最喜欢的编辑器在第 789 行编辑中打开它。像这样将其静音：

@$this->_max_cols = max($this->_max_cols, count($rowdata));

你可以走了。
