我正在尝试在我的帐户上安装sqlite3 ruby gem（版本1.3.4）（在共享主机上安装CentOS，所以我需要在没有根的情况下安装它），并且安装的sqlite版本对于sqlite3 ruby的更新版本来说还不够新，所以我需要在我的帐户下编译库。我使用的sqlite版本是1.7.0，因为我发现最近的版本有问题。
我已经完成了这项工作-我下载了sqlite-3.7.0.tar.gz并按如下方式安装：
./configure –prefix=$HOME
make && make install
然后转到我的Rails 3应用程序并运行以下程序：
bundle config build.sqlite3-ruby “--with-sqlite3-include=$HOME/include --with-sqlite3-lib=$HOME/lib”
然后：
bundle install --path vendor/bundle
但是，我得到了以下信息，我的包无法完全安装：

有什么想法吗？这以前是可行的，但在最近的sqlite3 ruby版本中，它似乎不再是一个可行的选择了。
以下是一些附加信息：
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=$HOME/lib
export USERNAME BASH_ENV PATH GEM_HOME GEM_PATH
which sqlite3
/home/striketh/bin/sqlite3
编辑：
我继续前进，在gemfile中将sqlite3 ruby更改为sqlite3，并运行以下命令：
bundle config build.sqlite3 “--with-sqlite3-include=$HOME/include --with-sqlite3-lib=$HOME/lib --with-sqlite3-dir=$HOME”
此错误消息使我：
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？
最佳答案
这是我验证过的解决方案。
.bash_配置文件设置：
# .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
