我正在使用带有ruby 2.0.0的RVM。当我尝试安装用于PostgreSQL的pg gem时,我收到以下回复。
gem install pg
这次出现了不同的错误。 gem install pg
假设它仍然试图从Ruby目录中获取openssl.so - 问题在于Ruby使用了错误的openssl.so文件。但事实是,我已经使用--with-openssl-dir标志重新编译了它。
有任何建议吗?我已经困在这个问题上超过10个小时了,尝试了我能找到的所有解决方法。

尝试通过谷歌搜索,显然问题出在OpenSSL库上,因为在mkmf.log输出中显示的是:

然后我使用指定的OpenSSL目录重新安装了Ruby。
openssl version -d
OPENSSLDIR: "/usr/lib/ssl"
rvm reinstall 2.0.0 --with-openssl-dir=/usr/lib/ssl
问题仍然存在。
尝试使用--with-pg-config标志安装gem。但问题依旧存在。
尝试了许多网站上常见的解决方法。
mv $rvm_path/usr/lib $rvm_path/usr/rvm_lib
gem install pg
mv $rvm_path/usr/rvm_lib $rvm_path/usr/lib
这次出现了不同的错误。 gem install pg
