ruby-on-rails – 即使安装了家用brew和应用程序,也无法安装PostgreSQL gem for rails

我试过跟随这个 answer来让宝石工作,但它不会.我有我的项目设置,以便个人项目有自己的宝石而不是生活在全球空间的所有主题宝石,然后我使用binstubs允许我做bin / rails之类的事情.

因此,对于每个项目,所有宝石都安装到.bundle / gems /.总是给我最棘手问题的是posgresql.让我们完成这些步骤.

所以我跑：

束

它爆炸说：

Gem files will remain installed in /Users/Adam/Documents/Rails-Projects/AisisPlatform/.bundle/gems/gems/pg-0.18.1 for inspection.
Results logged to /Users/Adam/Documents/Rails-Projects/AisisPlatform/.bundle/gems/gems/pg-0.18.1/ext/gem_make.out
An error occurred while installing pg (0.18.1),and Bundler cannot continue.
Make sure that `gem install pg -v '0.18.1'` succeeds before bundling.

那么,因为我在9.4.0安装了家用Brew版本并安装了posgresql.app然后我做了：

bundle config build.pg --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.3/bin/pg_config

接下来,因为我使用18.1

gem install pg -v '0.18.1'

我得到了：

Building native extensions.  This Could take a while...
Successfully installed pg-0.18.1
invalid options: -f fivefish
(invalid options are ignored)
Parsing documentation for pg-0.18.1
Done installing documentation for pg after 2 seconds
1 gem installed

从那里我尝试捆绑嗯我们回到原点,因为即使安装了宝石 – 我得到了完全相同的错误.

这是因为我在全局安装pg gem而不是本地安装吗？我怎样才能解决这个问题？这个项目,每次我必须做一个rm -rf .bundle / gems一次又一次地引起这个问题.

我应该指出即使我使用家庭酿造psql pg_config也会得到同样的错误.执行上述所有步骤,只需使用家庭酿造版本,结果相同.

解决方法

在一天结束时它是：

ARCHFLAGS="-arch x86_64" bundle install

这对我有用.

理由是：

by default it tries to compile a universal binary,which apparently
fails… so that environment variable makes it only compile the x86
version which is all you need

you can add this line to your ~/.profile or similar: export
ARCHFLAGS="-arch x86_64"
