location where your sqlite3 shared library is located).

Gem files will remain installed in /usr/local/lib/ruby/gems/2.0.0/gems/sqlite3-1.3.8 for inspection.

An error occurred while installing sqlite3 (1.3.8), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.3.8'` succeeds before bundling.

I then run the gem install sqlite3 -v '1.3.8' and get similar errors. I have no idea what I'm doing wrong.

然后我运行gem install sqlite3 -v'1.3.8'并得到类似的错误。我不知道我做错了什么。

Looks like you need to install sqlite

看起来你需要安装sqlite

That is where the

那就是

sqlite3.h is missing. Try 'port install sqlite3 +universal'
or 'yum install sqlite-devel'

If you have another db setup like postgres you can run it with the database switch

如果你有像postgres这样的另一个db设置，你可以使用数据库开关运行它

rails new myapp --database=postgresql

I found out I was missing developer dependencies when trying to use the MySQL gem. All is fixed now :)

我发现在尝试使用MySQL gem时我缺少开发人员依赖项。一切都修复了:)
