sqlite3 gem无法安装

Question

我正在尝试在OS X 10.6上安装“sqlite3-ruby”gem（或“sqlite3”gem）。 我正在使用ruby-1.9.2，目前我得到以下内容：

 $ sqlite3 --version
3.7.4
 $ sudo gem install sqlite3
Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3-ruby:
    ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/folken/.rvm/gems/ruby-1.9.2-head/gems/sqlite3-1.3.3 for inspection.

以下是其中＆whereis的结果，sqlite3.h位于/ opt / local / include中：

 $ which sqlite3
/opt/local/bin/sqlite3
 $ whereis sqlite3
/usr/bin/sqlite3

我也试过传递以下内容：

sudo gem install sqlite3 -- --with-sqlite3-include /opt/local/include --with-sqlite3-lib /opt/local/lib
sudo gem install sqlite3 -- --with-sqlite3-dir /opt/local/bin

这导致以下结果：

ERROR:  Error installing sqlite3-ruby:
    ERROR: Failed to build gem native extension.

    from extconf.rb:9:in `<main>'

也在/Users/folken/.rvm/gems/ruby-1.9.2-head/gems下：sqlite-ruby-2.2.3 sqlite3-1.3.3

在RVM下我有ruby-1.8.7并且sqlite3 gem加载得很好，但经过大量的谷歌搜索后我还没有找到适合我的解决方案。 非常感谢任何帮助（即使它涉及手动安装/ hackery工作）。

Answer 1

我有一个几乎类似的问题，因为我安装了sqlite3，但sqlite3 gem无法安装。 我看到如下错误信息，

user-name-rajas-macbook-pro:rails3 user-namer$ gem install sqlite3
Building native extensions.  This could take a while...
    ERROR:  Error installing sqlite3:
    ERROR: Failed to build gem native extension.

        /Users/user-namer/.rvm/rubies/ruby-1.9.2-p180/bin/ruby extconf.rb
checking for sqlite3.h... yes
checking for sqlite3_libversion_number() in -lsqlite3... no
sqlite3 is missing. Try 'port install sqlite3 +universal'
or 'yum install sqlite3-devel' and check your shared library search path (the
location where your sqlite3 shared library is located).

Gem files will remain installed in /Users/user-namer/.rvm/gems/ruby-1.9.2-    p180@rails_3/gems/sqlite3-1.3.3 for inspection.
Results logged to /Users/user-namer/.rvm/gems/ruby-1.9.2-p180@rails_3/gems/sqlite3-    1.3.3/ext/sqlite3/gem_make.out

这对我有用

gem install sqlite3 -- --with-sqlite3-dir=/opt/local

Answer 2

我使用ruby 1.9.2.p180和使用Mac OS X 10.5.8（Leopard）使用ruby 1.9.2.p180和rails 3.1.0.rc6跟踪rails3 in Action一书，当我跑步时：

rake cucumber:ok

我有：

Please install the sqlite3 adapter: `gem install activerecord-sqlite3-adapter` (can't activate sqlite3 (~> 1.3.4, runtime), already activated sqlite3-1.3.3. Make sure all dependencies are added to Gemfile.) 

然后我做了：

gem install sqlite3 -- --with-sqlite3-dir=/opt/local

其次是：

bundle install

希望在需要sqlite 1.3.5时，我会在Internet上找到自己的答案。

Answer 3

听起来你还没有安装过XCode。

Answer 4

对于osx，请确保已安装Xcode并且您已接受这些条款。 对我来说，我没有同意这些条款（无论出于何种原因，最近Xcode最近在我的电脑上安装或更新）。

1. 打开Xcode
2. 如果出现弹出窗口然后同意这些条款（如果你没有弹出，那么你可能已经接受了这些条款）。
