我一直在试图将数据从Trac 0.11迁移到Redmine 3.1.1，它们都在同一台机器上，Windows Server 2012.我用Bitnami安装了redmine 3.1.1，并遵循这个迁移指南：http://www.redmine.org/projects/redmine/wiki/RedmineMigrate，sqlite3-ruby除外，因为当我安装sqlite3-ruby gem时，它说它重命名为sqlite3，所以用它代替。然后我按照以下命令安装了sqlite3 gem。从Trac迁移到Redmine，并给出错误说'宝石sqlite3未加载'
gem install --local C:\Users\Administrator\Downloads\sqlite3-1.3.11.gem -- --with-sqlite3-include=D:\Bitnami\redmine-3.1.1-1\sqlite --with-sqlite3-lib=D:\Bitnami\redmine-3.1.1-1\sqlite --with-sqlite3-dir=D:\Bitnami\redmine-3.1.1-1\sqlite
该服务器有一个防火墙，所以我下载sqlite3的宝石，并从本地文件夹中安装它。
宝石列表显示了以下
*** LOCAL GEMS ***
bigdecimal (1.2.0)
bundler (1.9.6)
io-console (0.4.2)
json (1.7.7)
minitest (4.3.2)

rake (0.9.6)
rdoc (4.0.0)
sqlite3 (1.3.11)
sqlite3-ruby (1.3.3)
test-unit (2.0.0.0)
执行rake命令之前，我不得不修复的migrate_from_trac.rake为这篇文章建议：http://www.redmine.org/issues/19173顺便说一句，该文件位于d：\ Bitnami \ redmine-3.1.1-1 \ apps \ redmine \ htdocs \ lib \ tasks \ migrate_from_trac.rake
然后我在D：\ Bitnami \ redmine-3.1.1-1 \ apps \ redmine \ hdocs，
bundle exec rake redmine:migrate_from_trac RAILS_ENV="production" --trace

Tasks: TOP => redmine:migrate_from_trac
所以，我添加了以下行到Gemfile中它位于d：\ Bitnami \管理平台-3.1.1-1 \ APPS \管理平台\ htdocs目录
gem 'sqlite3', '1.3.11'
但它并没有改变什么，在上面的命令仍然给我同样的错误。我也试了几个包命令，下面
bundle install
You are trying to install in deployment mode after changing
your Gemfile. Run `bundle install` elsewhere and add the
updated Gemfile.lock to version control.
If this is a development machine, remove the Gemfile freeze
by running `bundle install --no-deployment`.
You have added to the Gemfile:
* sqlite3 (= 1.3.11)
但是，我无法找到有关Gemfile.lock的sqlite3的任何线路。我认为这可能是Gemfile.lock文件的问题，因此我删除了Gemfile.lock并执行了bundle install命令，如下所示重新创建它，但它没有生成Gemfile.lock。
build install

我忘了提，所有的事情都通过点击d use_redmine.bat上Bitnami管理平台堆栈环境中进行：\ Bitnami \管理平台-3.1.1-1。
