Question

我安装了rbenv，ruby和rails，但是创建新rails项目的命令导致了sqlite的异常。

rails new first_app

sqlite3.h is missing. Try 'port install sqlite3 +universal'
or 'yum install sqlite-devel' and check your shared library search path (the
location where your sqlite3 shared library is located).

An error occurred while installing sqlite3 (1.3.6), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.3.6'` succeeds before bundling.

我已尝试安装sqlite gem并重新发布rbenv，但同样的错误。有没有人对如何解决这个问题有什么想法，确切的宝石名称是什么，等等？

Answer 1

我有同样的问题，我在ubuntu上安装了一个sqlite包：

apt-get install libsqlite3-dev

Answer 2

问题是您缺少编译mysql适配器所需的头文件。该错误表明＆＃34;尝试端口安装sqlite3 + universal＆＃39;或者＆＃39; yum install sqlite-devel＆＃39;并检查您的共享库搜索路径（sqlite3共享库所在的位置）＆＃34;。我会首先这样做，因为这将确保您的计算机上有正确的头文件。一旦你拥有它们，你可能必须为编译器指定文件的位置，＆＃34; - with-sqlite3-include＆＃34;指令可能会成功。

Answer 3

您的盒子上似乎没有安装 sqlite 。如果没有底层存在，宝石将不会安装。

请做：

macosx：brew install sqlite
enterprise linux：sudo yum install libsqlite3-dev
ubuntu：sudo apt-get install libsqlite3-dev

“rails new”命令出错（使用rbenv）
