Question

使用 Mac OS X 10.5.8（Leopard）红宝石1.9.3p0 宝石版1.8.14 sqlite3版本3.7.9

我也安装了Xcode 3.1.4（不确定这是否用于安装宝石）。

我获取了sqlite3 gem

gem fetch sqlite3

然后解压缩

gem unpack sqlite3-1.3.5.gem

然后进入新目录

cd sqlite3-1.3.5

已执行

ruby setup.rb config

然后cd到了ext / sqlite3

然后执行make

这将返回以下错误消息：

usernamemac:sqlite3 username$ make

database.c:47: error: 'SQLITE_OPEN_READWRITE' undeclared (first use in this function)

database.c:285: error: 'sqlite3_int64' undeclared (first use in this function)
database.c:285: error: syntax error before 'long'
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（详见www.sqlite.org/compile.html）”，但不明白应该做什么。

有谁可以帮我解决这个问题？

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

时遇到类似问题

rails new app1 -d mysql

我已经安装了gem mysql2（0.3.11）。

更新2：执行时

gem update

当更新sqlite3-ruby gem时，我得到以下内容：

Answer 1

如果您运行的是Mac OS 10.5.X或更低版本，则无法运行sqlite3。你至少需要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'

无法在Mac OS X 10.5.8（Leopard）上安装sqlite3 gem
