Question

我使用mac。

宝石版：2.4.5.1 Ruby版本：ruby 2.2.3p173（2015-08-18修订版51636）[x86_64-darwin15] 的Gemfile：

source 'https://rubygems.org'

gem 'rails', '3.2.3'

group :development do
    gem 'sqlite3', '1.3.5'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '3.2.4'
  gem 'coffee-rails', '3.2.2'

  gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.1'

group :production do
    gem 'pg', '0.12.2'
end

我花了大约3个小时搜索解决方案，没有运气。

我阅读了Ruby on Rails教程＆＃39;作者：Michael Hartl，第46页。

第一个导致另一个错误的错误导致另一个......

从这个命令开始：

bundle install --without production

An error occurred while installing sqlite3 (1.3.5), and Bundler cannot
continue.
Make sure that `gem install sqlite3 -v '1.3.5'` succeeds before bundling.

然后，由于最后一句＆＃34;在捆绑之前确保gem install sqlite3 -v '1.3.5'成功。＆＃34;，我运行那个命令：

gem install sqlite3 -v '1.3.5'

得到这个错误，我不知道该怎么做：

我在this主题上尝试了这些建议，但所有建议都返回＆＃34;未找到命令＆＃34;。

我也按照this帖子的建议尝试运行gem install sqlite3-ruby，但是没有用。

我尝试按this主题中的建议运行gem sources --add http://rubygems.org/，以防失败与HTTPS或HTTP有关，但无法正常工作。

有什么建议吗？

谢谢！纳斯

Answer 1

请尝试按以下方式安装：

gem install sqlite3 -v'1.3.5' - --srcdir = / usr / local / mysql / include

Answer 2

试

bundle update sqlite3

Answer 3

您是否在系统中安装了SQLite3？

如果您使用的是MacPorts：

sudo port install sqlite3

或Brew：

brew install sqlite3

无法安装sqlite
