当我跑(以root身份)
gem install pg -v '0.12.0' -- --with-pg-config=/usr/pgsql-9.1/bin/pg_config
我得到以下输出:
#-> gem instal pg -v '0.12.0' -- --with-pg-config=/usr/pgsql-9.1/bin/pg_config
Building native extensions. This could take a while...

当我运行bundle install时:
Installing pg (0.12.0) with native extensions

Reason: Incompatible library version: _psycopg.so requires version 1.0.0 or later, but libssl.0.9.8.dylib provides version 0.9.8
pip freeze显示psycopg2==2.4.5恰到好处.我已经在几个virtualenvs上安装了psycopg2,但这是我第一次看到这样的错误.我尝试卸载并重新安装,结果相同.请帮忙
当我尝试在开发模式下访问我的Ruby on Rails网站时,我收到以下"不兼容的库版本"错误.
