Sqlite3 导致捆绑安装和 gem 安装出现问题

Question

使用 Rails，每当我尝试执行“bundle install”或 sudo gem install someGem 之类的操作时，我都会收到有关 sqlite3 的这些相同错误。我都尝试过

sudo port install sqlite3 +universal

，

sudo port install rb-sqlite3 +universal

但都没有帮助。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.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb

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.  
Check the mkmf.log file for more details.  
You may need configuration options.

Provided configuration options:     
--with-opt-dir  
--without-opt-dir   
--with-opt-include  
--without-opt-include=${opt-dir}/include

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，以下是其内容：

Answer 1

弄清楚了：

1. “which -a ruby​​”和“which -a
   sqlite3”和“which -a gem”
   意识到我有两三个版本
   每个

2. port 卸载其已安装的所有 Ruby、Sqlite3 和 ruby​​gems 版本

3. 手动卸载其他版本sqlite3 不一样
   路径为 Ruby 和 Rubygems

4. 一旦 Ruby、Rubygems 和 Sqlite3 都处于同一浴中
   (usr/bin) 一切又恢复正常了。
