ruby-on-rails - 通过 bundler 安装 sqlite3 gem 时出错

Question

我正在尝试在我的帐户上安装 sqlite3-ruby gem(版本 1.3.4)(共享主机上的 CentOS，所以我需要在没有 root 的情况下安装它)并且安装的 sqlite 版本不够新更新版本的 sqlite3-ruby，所以我需要编译我帐户下的库。我使用的 sqlite 版本是 1.7.0，因为我发现较新的版本存在问题。

我已经这样做了——我下载了 sqlite-3.7.0.tar.gz 并按如下方式安装:

./configure –prefix=$HOME
make && make install

然后转到我的 Rails 3 应用程序并运行以下命令:

bundle config build.sqlite3-ruby “--with-sqlite3-include=$HOME/include --with-sqlite3-lib=$HOME/lib”

然后:

bundle install --path vendor/bundle

但是，我得到以下信息并且我的包无法完全安装:

Installing sqlite3 (1.3.4) with native extensions /usr/lib/ruby/site_ruby/1.8/rubygems/installer.rb:533:in `build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)

有什么想法吗？这曾经有效，但随着更新版本的 sqlite3-ruby 的出现，它似乎不再可行了。

这里有一些额外的信息:

rails -v
Rails 3.0.9

gem -v
1.7.2

.bash_profile:

PATH=$HOME/bin:$PATH
GEM_HOME=$HOME/gems
GEM_PATH=$HOME/gems
export LD_LIBRARY_PATH=$HOME/lib
export USERNAME BASH_ENV PATH GEM_HOME GEM_PATH

which sqlite3
/home/striketh/bin/sqlite3

编辑:

我继续在我的 Gemfile 中从 sqlite3-ruby 更改为 sqlite3 并运行以下命令:

bundle config build.sqlite3 “--with-sqlite3-include=$HOME/include --with-sqlite3-lib=$HOME/lib --with-sqlite3-dir=$HOME”

这条错误信息让我明白了:

make
gcc -I. -I. -I/usr/lib/ruby/1.8/x86_64-linux -I. -DHAVE_SQLITE3_INITIALIZE -DHAVE_SQLITE3_BACKUP_INIT -I/home/striketh”/include    -fPIC -g -O2  -fPIC   -c sqlite3.c
In file included from ./sqlite3_ruby.h:42,
                 from sqlite3.c:1:
./backup.h:7: error: expected specifier-qualifier-list before 'sqlite3_backup'
make: *** [sqlite3.o] Error 1

还有其他想法吗？

Answer 1

这是我已经验证有效的解决方案。

.bash_profile 设置:

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$HOME/bin:$PATH
GEM_HOME=$HOME/gems
GEM_PATH=$HOME/gems
export LD_LIBRARY_PATH=$HOME/lib
export USERNAME BASH_ENV PATH GEM_HOME GEM_PATH

然后运行:

wget http://www.sqlite.org/sqlite-autoconf-3070701.tar.gz
tar -zxvf sqlite-autoconf-3070701.tar.gz
cd sqlite-autoconf-3070701
./configure --prefix=$HOME
make && make install

cd $RAILS_APP_DIR
vi Gemfile

确保 Gemfile 中有与此类似的行:gem 'sqlite3', "1.3.4"

bundle config build.sqlite3 --with-sqlite3-include=$HOME/include --with-sqlite3-lib=$HOME/lib --with-sqlite3-dir=$HOME/bin
bundle install --path vendor/bundle
