使用
Mac OS X 10.5.8(豹)
ruby 1.9.3p0
gem 版本 1.8.14
sqlite3 版本 3.7.9
我还安装了 Xcode 3.1.4(不确定这是否用于安装 gems)。
我拿了 sqlite3 gem
gem fetch sqlite3
然后拆开包装
gem unpack sqlite3-1.3.5.gem
并 cd 进入新目录
cd sqlite3-1.3.5
执行
ruby setup.rb config
然后 cd 到 ext/sqlite3
然后执行 make
这将返回以下错误消息:
usernamemac:sqlite3 username$ make

make: *** [database.o] Error 1
在 gem 的 README.rdoc 文件中，我读到了“启用选项 SQLITE_ENABLE_COLUMN_METADATA(有关详细信息，请参阅 www.sqlite.org/compile.html)”，但不明白应该做什么。
谁能帮我解决这个问题？
我尝试过其他方法，例如
Error with MySql while doing Bundle Install
和 I can't install sqlite3 gem但这些对我不起作用。
更新:我在尝试时遇到了类似的问题
rails new app1 -d mysql
create vendor/plugins/.gitkeep
run bundle install

最佳答案
如果您运行的是 Mac OS 10.5.X 或更低版本，则无法运行 sqlite3。您至少需要 Snow Leopard 才能编译它。
而是尝试更改您的 Gemfile 以使用 sqlite3-ruby 1.2.5
gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
关于ruby-on-rails - 无法在 Mac OS X 10.5.8 (Leopard) 上安装 sqlite3 gem，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/8765071/
