【问题描述】：
我整天都在网上搜索解决方案，但似乎无法找到解决此特定问题的方法；我见过几乎相同的查询，但我对这些解决方案没有成功。 我刚刚开始了一个月的 Rails，每次我尝试像这样创建一个新应用程序时：

一切顺利，一旦捆绑安装完成，我会收到这个迷宫般的错误消息

我在其他地方看到了一些关于安装 sqlite3 的回复，但没有一个在这里起作用，特别是涉及一个“yum”命令，当我插入它时它无法识别：
yum install sqlite-devel
之后我只得到：
-bash: yum: command not found
我对自己做错了什么或忽略了什么完全不知所措，需要一位经验更丰富的 ruby 程序员给我一双新的眼睛！
【问题讨论】：
-
尝试 sudo apt-get install sqlite-devel 或只是 apt-get install sqlite-devel。我更喜欢 mysql/pgsql 而不是 sqlite3...
-
它清楚地写着
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.，这意味着你需要安装开发工具。你也在 Mac 上，所以你需要brew来安装包，而不是yum -
我有类似的问题，在我的系统上安装 ruby-devel 后，错误消失了。不过，您的系统可能缺少其他头包。
