Sqlite3 导致捆绑安装和 gem 安装问题

Question

使用 Rails 时，每当我尝试执行“捆绑安装”或 sudo gem install someGem 之类的操作时，都会遇到关于 sqlite3 的相同错误。我都试过了

sudo port install sqlite3 +universal

和

sudo port install rb-sqlite3 +universal

但两者都没有帮助。这是错误：

cmu-435163:photoGlass dpieri$ sudo gem install taps 
Password: 
Building native extensions.  
This could take a while... 
ERROR:  Error installing taps:  
    ERROR: Failed to build gem native extension.

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).
*** extconf.rb failed *** 
Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.

You may need configuration options.

Provided configuration options:

--without-opt-dir

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/sqlite3-1.3.3 for inspection. Results logged to /Library/Ruby/Gems/1.8/gems/sqlite3-1.3.3/ext/sqlite3/gem_make.out

更新： 我找到了 mkmf.log 文件，下面是它的内容：

Answer 1

想通了：

1. 做了“which -a ruby​​”和“which -a sqlite3" 和 "which -a gem" 到 意识到我有两个或三个版本 每个

2. 使用 port 卸载所有已安装的 Ruby、Sqlite3 和 ruby​​gems 版本

3. 手动卸载其他不一样的sqlite3 Ruby 和 Rubygems 的路径

4. 曾经 Ruby、Rubygems 和 Sqlite3 都在同一个浴缸里 (usr/bin) 一切正常。
