我在sqlite3-ruby安装期间出现以下错误:

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

    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog …

尝试将NOT NULL列添加到现有表时,我收到以下错误.为什么会这样？我试过rake db:reset认为现有记录是问题,但即使重置数据库后,问题仍然存在.你能帮我搞清楚吗？

迁移文件

class AddDivisionIdToProfile < ActiveRecord::Migration
  def self.up
    add_column :profiles, :division_id, :integer, :null => false
  end

  def self.down
    remove_column :profiles, :division_id
  end
end

错误信息

SQLite3 :: SQLException:无法添加带有默认值NULL的NOT NULL列:ALTER TABLE"profiles"ADD"division_id"integer NOT NULL

升级到OSX Sierra后,我遇到了随机分段错误的问题.它最常出现在运行rails测试时,我相信它是由sqlite3_adapter引起的.

我目前的工作是简单地退出终端并重新启动它.这适用于大约1或2个轨道测试,而第三个我几乎可以保证得到另一个分段故障.

是否有其他人遇到此问题或找到更好的解决方法？

$ rails t

/Users/USER/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/activerecord-5.0.0.1/lib/active_record/connection_adapters/sqlite3_adapter.rb:27: [BUG] Segmentation fault at 0x00000000000110
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin16]

编辑:

在深入研究sqlite3_adapter.rb后,我发现导致分段错误的行是创建一个新的SQlite3数据库.

db = SQLite3::Database.new(
    config[:database].to_s,
    :results_as_hash => true
)

编辑2:

我没有退出并重新启动终端,而是发现运行:

spring stop

暂时停止问题.不是解决方案,而是更好的解决方案.

编辑3:

这似乎是Apple提供的libsqlite3不是叉安全的问题.更多信息可以在这里找到:

https://github.com/sparklemotion/sqlite3-ruby/issues/195

现在,我在〜/ .bashrc文件的底部创建了一个别名:

alias ss='spring stop'

出现问题时,我现在可以输入:

ss

然后重新运行测试.

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

ERROR:  Error installing sqlite3-ruby:

    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir …

我不小心跑了:

sudo gem install sqlite3

代替:

sudo gem install sqlite3-ruby

所以现在当我运行gem list时,我得到:

gem list

*** LOCAL GEMS ***

sqlite3 (0.0.7)
sqlite3-ruby (1.2.5)

两者有什么区别？我需要两个吗？

在新机器上,使用Windows的1-click安装程序安装ruby.安装了rails 2.3.2和所有相关的gem,然后我安装了sqlite3二进制文件(进入c:\ ruby​​\bin文件夹).最后我做了gem install sqlite3-ruby -v=1.2.3(这显然是与Windows一起使用的最新版本)

运行时rake db:migrate或在运行时触摸任何ActiveRecord对象时会发生此错误.

错误如下所示:

** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:migrate
rake aborted!
**uninitialized constant Encoding**  <----

任何帮助解决此错误将不胜感激!

试图在ubuntu上获得Rails,我在安装sqlite3-ruby时遇到了麻烦 - 显然无法找到sqlite3.h.我可以找到错误的所有引用都表明问题是:未安装sqlite3头文件,或者make无法找到它们.在我看来,我已经解决了这两个问题,我仍然看到同样的问题.

不知道这里发生了什么.版本不匹配,也许？这是在ubuntu 10.04.1上使用ruby 1.8.7,sqlite 3.6.22-1,gem 1.3.5和sqlite3-ruby 1.3.1.

我在crunchbang linux上安装sqlite3-ruby gem时遇到问题.谷歌搜索过去几个小时,并跟随几个有同样问题的人,我仍然没有得到它的工作.

这是我在尝试'sudo gem install sqlite3-ruby'之后看到的

接下来我跑过这个页面; http://groups.google.com/group/sqlite3-ruby/browse_thread/thread/f22d098b561c48af/6e754f7b2fc3cd75?#6e754f7b2fc3cd75

我下载了sqlite-amalgamation-3.7.0.1.tar.gz并发出以下命令:

tar zxvf sqlite-amalgamation-3.7.0.1.tar.gz
cd cd sqlite-3.7.0.1
mkdir $ HOME/sqlite
./configure --prefix = $ HOME/sqlite
make && make install
sudo gem install sqlite3-ruby - -与-sqlite3的-DIR = $ HOME /源码

但是,我仍然得到完全相同的错误.我使用'sudo apt-get install sqlite3 libsqlite3-dev',但我仍然得到完全相同的错误.

有什么建议？

而作为一个小小的一边,为什么当我使用'sudo apt-get install sqlite3'时,它抓取3.5.9而不是我手动下载的3.7.0.1？

我是Rails的新手,我正在为我的雇主构建一个简单的项目跟踪应用程序.我一直在我的Mac上开发应用程序并将其推送到github.我只是设法将我的github repo克隆到我公司防火墙后面的一个Windows框中,希望让同事们试用这个应用程序.

但是当我去rake db:migrate来初始化windows框中的数据库时,我收到以下错误消息:

$ rake db:migrate --trace
** Invoke db:migrate (first_time)
