安装 pg gem 时遇到问题 [英] Trouble installing pg gem

问题描述

尝试安装 pg gem 时出现错误.

Trying to install the pg gem gives me errors.

我正在使用使用 rbenv/ruby-build 构建的 Ruby 1.9.3-p125.我使用一键式安装程序安装了 PostgreSQL.我可以使用 pgAdmin 连接到数据库.我的想法不多了.

I'm using Ruby 1.9.3-p125 built using rbenv/ruby-build. I installed PostgreSQL using the one-click installer. I'm able to connect to the DB using pgAdmin. I'm running out of ideas.

% gem install pg                                                                                                                                                                                                      ~

推荐答案

不确定以下哪个步骤最终解决了这个问题.但由于 mu 太短，问题在于混合 32 位和 64 位二进制文​​件.

Not sure which of the following steps finally cleared this issue up. But as mu is too short mentioned, the problem was mixing 32bit and 64bit binaries.

• 第一，我安装了这个64位版本的PostgreSQL

• 第二，我卸载了任何旧的 Homebrew OpenSSL 安装

• 1st, I installed this 64-bit version of PostgreSQL

• 2nd, I uninstalled any old Homebrew OpenSSL installation

$ brew uninstall openssl

$ brew uninstall openssl

第三，我用 Homebrew 安装了 64 位版本的 OpenSSL

3rd, I installed the 64-bit version of OpenSSL with Homebrew

$ brew install --64-bit openssl

$ brew install --64-bit openssl

最后，在安装 pg gem 时，我将 LDFLAGS 更改为指向 64 位版本的 OpenSSL

Lastly, when installing the pg gem, I changed the LDFLAGS to point to the 64-bit version of OpenSSL

$ gem install pg -- --with-ldflags='-L/usr/local/Cellar/openssl/0.9.8s'

$ gem install pg -- --with-ldflags='-L/usr/local/Cellar/openssl/0.9.8s'
