Question

我花了好几个小时试图找出它为什么不起作用后，终于设法得到了'pg'宝石安装......

最后我输入sudo env ARCHFLAGS="-arch x86_64" gem install pg -v 0.12.2 -- --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config，就像一个魅力。但是现在我尝试捆绑时仍然有同样的错误 - 所以我猜我没有真正解决问题？无论如何，这是bundle install所说的：

我认为问题是bundler尝试使用另一个postresql安装（我已删除）的pg_config来安装gem。有没有办法确保捆绑器使用正确的路径？

Answer 1

我被捆绑安装了3天。试着加入env ARCHFLAGS =“ - arch x86_64”gem install pg - --with-pg-config = / usr / local / Cellar / postgresql / 9.3.5_1 / bin / pg_config

我能够看到pg gem在此命令之后安装，但它仍然没有从bundle install安装，这很痛苦，因为我知道在Gemfile中写什么，除了gem'pg'

最终对我有用的是发现我的pg_config位于/Library/PostgreSQL/9.3/bin/pg_config中，默认情况下，Gemfile包安装在/ usr / local / bin / pg_config中查找

我刚刚运行了以下命令并且发生了魔法。 捆绑配置build.pg --with-pg-config = / Library / PostgreSQL / 9.3 / bin / pg_config

一些纠正。对于那些使用自制软件安装postgres的人。

1）在〜/ .bash_profile

中写下以下行

导出ARCHFLAGS =＆＃34; -arch x86_64＆＃34;

2）重启控制台

3）执行以下命令

捆绑配置build.pg --with-pg-config = / usr / local / Cellar / postgresql / 9.3.5_1 / bin / pg_config （这必须是你的pg配置地址，每个都可以根据postgres的版本而有所不同）

4）通过运行此命令在本地安装pg

sudo env ARCHFLAGS =＆＃34; -arch x86_64＆＃34; gem install pg - --with-pg-config = / usr / local / Cellar / postgresql / 9.3.5_1 / bin / pg_config

5）捆绑安装

无法安装pg gem
