pdo sqlite驱动问题

Question

我刚开始使用 laravel，当我尝试从 sqlite 返回文章 JSON 时，我收到此驱动程序错误。

public function index(){
    $articles = \App\Article::all();
    return $articles;
}

哎呀，好像出了点问题。 Connector.php 第 55 行中的 1/1 PDOException：找不到驱动程序

Answer 1

请确保您已正确安装pdo 和pdo_sqlite 扩展。

php -v 将输出是否缺少任何扩展文件。

你应该有这些包 sqlite, php5-sqlite 。并用pecl建造。 pecl install pdo && pecl install pdo_sqlite 。最后，您应该在 php.ini 中启用 pdo、pdo_sqlite 扩展。根据您的 phpinfo() 输出，您的 php.ini 文件为 /etc/php/php.ini

再次根据您的 phpinfo() 输出，您的扩展文件夹是 /usr/lib/php/modules/ 。该目录下应该有pdo_sqlite.so文件。

我发现如果我们可以写入数据库，那么连接工作正常。尝试从数据库中检索时，我们都遇到了这个问题。我通过重新启动服务器解决了这个问题。这在 Ubuntu 14.04 中对我有用
