【问题描述】：

如here 所述，我安装了运行 mongify 所需的所有实用程序，但我仍然收到此错误 -

/home//.rvm/rubies/ruby-2.3.0/lib/ruby/site_ruby/2.3.0/rubygems.rb:270:in `find_spec_for_exe': can't find gem mongify (>= 0.a) (Gem::GemNotFoundException)
    from /home//.rvm/rubies/ruby-2.3.0/lib/ruby/site_ruby/2.3.0/rubygems.rb:298:in `activate_bin_path'
    from /home//.rvm/gems/ruby-2.3.0/bin/mongify:22:in `<main>'
    from /home//.rvm/gems/ruby-2.3.0/bin/ruby_executable_hooks:15:in `eval'
    from /home//.rvm/gems/ruby-2.3.0/bin/ruby_executable_hooks:15:in `<main>'

这是我的宝石清单：

【参考方案1】：

你是如何安装 gem mongify 的？如果您使用bundler，它将帮助您修复所有依赖项，例如

» 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. This could take a while...

当我在终端上运行 mongify 时，这是我得到的错误 - /home/.rvm/rubies/ruby-2.3.0/lib/ ruby/site_ruby/2.3.0/rubygems.rb:270:in find_spec_for_exe': can't find gem mongify (>= 0.a) (Gem::GemNotFoundException) from /home/.rvm/rubies/ruby-2.3.0/lib/ruby/site_ruby/2.3.0/rubygems.rb:298:in activate_bin_path' 来自 /home/.rvm/gems/ruby-2.3.0/bin/mongify:22:in <main>' from /home/.rvm/gems/ruby-2.3.0/bin/ruby_executable_hooks:15:in eval' 来自 /home /.rvm/gems/ruby-2.3.0/bin/ruby_executable_hooks:15:in `

您当前的用户是什么？ root 还是你自己？您粘贴的位置内容很奇怪，请检查您当前的用户。

您可以尝试更新gem 和bundler 吗？然后再次bundle install。

当前用户是我自己。当我运行 update_rubygems 时出现此错误 - /home/.rvm/rubies/ruby-2.3.0/lib/ruby/site_ruby/2.3.0 /rubygems.rb:270:in find_spec_for_exe': can't find gem rubygems-update (>= 0.a) (Gem::GemNotFoundException) from /home/.rvm/rubies/ruby-2.3.0/lib/ruby/site_ruby/2.3.0/rubygems.rb:298:in activate_bin_path' 来自 /home/.rvm/gems/ruby-2.3.0/bin/update_rubygems:22:in <main>' from /home/.rvm/gems/ruby-2.3.0/bin/ruby_executable_hooks:15:in eval' 来自 /home/.rvm/gems/ruby -2.3.0/bin/ruby_executable_hooks:15:in `

【参考方案2】：

这是一个宝石错误。

首先你需要找到'Gemfile'

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

然后运行 ​​- bundle install --with production

然后如果没有安装运行- gem install mysql2

现在所有必需的 gem 都已安装。

现在运行 - mongify

现在如果 mongify 正在工作，你需要检查 SQL 和 NoSQL 的连接

所以运行 - mongify 检查 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 连接有效

NoSQL 连接有效

然后运行 ​​- mongify translation database.config > translation.rb

和 - mongify process database.config translation.rb

现在数据将从 MySQL DB 迁移到 MongoDB。

那么原因是安装了gemmysql适配器？

是的，而且所有必需的捆绑包都没有安装

【参考方案3】：

For Mac:
 1.  Download and install the mysql installer. (https://dev.mysql.com/downloads/mysql/)
 Open Terminal
 2.  sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
