无法安装PG宝石(Cannot install pg gem)

我终于设法得到“PG”宝石花时间试图弄清楚为什么它不工作后安装...

最后我进入sudo env ARCHFLAGS="-arch x86_64" gem install pg -v 0.12.2 -- --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config这工作就像一个魅力。 但是现在我仍然有同样的错误，当我尝试捆绑 - 所以我想我并没有真正解决问题呢？ 总之，这里就是bundle install时说：

我认为这个问题是捆绑试图安装使用来自另一个postresql安装pg_config（我已经删除）的宝石。 有没有什么办法，以确保打捆使用了正确的道路？

Answer 1:

我被困在我的包安装3天。 想尽一切如添加ENV ARCHFLAGS = “ - 拱x86_64的” 创业板安装PG - --with-PG-配置=在/ usr /本地/库/ PostgreSQL的/ 9.3.5_1 /斌/ pg_config

我能看到越来越安装此命令后，皮克宝石但仍没有从安装包安装，这是一个痛苦，因为我不力知道在Gemfile中除了写宝玉“PG”

这终于为我工作的事就是发现我pg_config是/Library/PostgreSQL/9.3/bin/pg_config，默认情况下的Gemfile捆绑安装在/ usr / local / bin目录/ pg_config外观

我只是跑以下命令，奇迹发生了。 束的配置build.pg --with-PG-配置= /库/ PostgreSQL的/ 9.3 / bin中/ pg_config

Answer 2:

一些修正。 对于那些谁使用自制安装的Postgres。

1）写出下面的行放在〜/ .bash_profile中

出口ARCHFLAGS = “ -拱x86_64的”

2）重新启动控制台

3）执行以下命令

捆绑配置build.pg --with-PG-配置=在/ usr /本地/库/ PostgreSQL的/ 9.3.5_1 /斌/ pg_config（这必须是您的PG配置地址有差别，可为每个取决于Postgres的版本）

4）通过运行该命令安装PG一旦本地

须藤ENV ARCHFLAGS = “ -拱x86_64的”创业板安装PG - --with-PG-配置=在/ usr /本地/库/ PostgreSQL的/ 9.3.5_1 /斌/ pg_config

5） 捆绑安装
