Question

我一直在尝试运行捆绑安装，但我收到以下错误：

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

    /Users/fr/.rvm/rubies/ruby-2.0.0-p247/bin/ruby extconf.rb
checking for pg_config... no
No pg_config... trying anyway. If building fails, please try again with
 --with-pg-config=/path/to/pg_config
checking for libpq-fe.h... no
Can't find the 'libpq-fe.h header
*** extconf.rb failed ***

按照说明操作后，我收到以下错误：

gem install pg -v '0.17.0'                                                    ⏎
Building native extensions.  This could take a while...
ERROR:  Error installing pg:

我按照之前报告的类似问题提供的说明进行操作。请参阅Installing PG gem - failure to build native extension

但这没有帮助，如下所示：

brew install postgresql
Warning: Could not link postgresql. Unlinking...
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link postgresql'

Possible conflicting files are:
==> /usr/local/Cellar/postgresql/9.3.4/bin/initdb /usr/local/var/postgres
==> Summary
  /usr/local/Cellar/postgresql/9.3.4: 2928 files, 38M


brew link postgresql
Linking /usr/local/Cellar/postgresql/9.3.4...
Warning: Could not link postgresql. Unlinking...
Error: Could not symlink file: /usr/local/Cellar/postgresql/9.3.4/share/man/man7/WITH.7
/usr/local/share/man/man7 is not writable. You should change its permissions.

我的两个问题是：

如何解决与＆＃39; pg＆＃39;相关的问题？宝石？
要解决此问题，是否有必要修改 brew link postgresql 输出中提到的文件的读写权限？

Answer 1

我设法解决了问题。主要问题是 pg版本 - 0.17.0 。我安装了最新的Postgres.app并在安装后验证版本为 0.17.1 。然后我将gem文件修改为gem 'pg'并运行bundle update。感谢大家的建议和链接。

Postgresql Gem没有安装
