你是如何安装宝石<?php $var1 = $_POST['var1']; $var2 = $_POST['var2']; $getvalue="SELECT id,name from table1 WHERE column1='$var1' and column2='$var2'"; $result=mysql_query($getvalue) or die(mysql_error()); while($row=mysql_fetch_array($result)){ extract($row); echo $name; } ?>的？如果您使用mongify，它将帮助您修复所有依赖项，例如

bundler 或者，您确定在安装该宝石时出错了吗？检查了您的错误消息，看起来您执行了宝石cli » gem install mongify Fetching: activemodel-4.2.7.1.gem (100%) Successfully installed activemodel-4.2.7.1 Fetching: arel-6.0.4.gem (100%) Successfully installed arel-6.0.4 Fetching: activerecord-4.2.7.1.gem (100%) Successfully installed activerecord-4.2.7.1 Fetching: bson-1.12.5.gem (100%) Successfully installed bson-1.12.5 Fetching: mongo-1.12.5.gem (100%) Successfully installed mongo-1.12.5 Fetching: bson_ext-1.12.5.gem (100%) Building native extensions.

这是一个宝石错误。

首先，您需要找到“ Gemfile ”

然后运行 - cd /.gemspecs/did_you_mean-1.0.0

然后运行 - 捆绑安装 - 生产

然后如果没有安装run- gem install mysql2

现在安装了所有必需的宝石。

现在运行 - mongify

现在如果mongify工作，你需要检查SQL和NoSQL的连接

所以运行 - mongify check database.config

在database.config文件中，你需要这个 -

sql_connection do
adapter   "mysql2"
host      "127.0.0.1"
username  "root"
password  "root"
database  "database_name"
end    

mongodb_connection do
host      "127.0.0.1"
database  "database_name"
end

现在你会看到 -

SQL连接正常工作

NoSQL连接正常工作

然后运行 - mongify translation database.config＆gt; translation.rb

和 - mongify process database.config translation.rb

现在数据将从MySQL DB迁移到MongoDB。
