rails mysql gem_用於Ruby On Rails的MySQL Gem

I have searched everywhere and no ones solutions solve my problem. I have built rails apps using SQLite but not MySQL. For this particular project, I need MySQL. When I attempt to boot the server I get an error, so I attempt to install the gems for MySQL and get another error. Does anyone have any insight? Thank you!

我到處搜索，沒有解決方案解決我的問題。我使用SQLite而不是MySQL構建了rails應用程序。對於這個特定的項目，我需要MySQL。當我嘗試啟動服務器時出現錯誤，因此我嘗試為MySQL安裝gems並獲得另一個錯誤。有沒有人有任何見解？謝謝！

rails server

Could not find gem 'mysql2 (>= 0)' in any of the gem sources listed in your Gemfile.

sudo gem install mysql2

Building native extensions. This could take a while...

I had this problem. You need to install the mysql gem with native extensions.

我有這個問題。您需要使用本機擴展安裝mysql gem。

The line you're probably looking for is this:

您可能正在尋找的這條線是這樣的：

$ ARCHFLAGS="-arch x86_64" gem install mysql2 --version '~> 0.2.7' -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
