我试过了在stackoverflow上找到的所有内容，但仍然收到此错误消息。

如果我尝试使用brew安装postgresql，我会得到以下结果：

警告：已经安装postgresql-9.2.4，它只是没有链接

如果我尝试链接

brew链接postgresql链接/usr/local/Cellar/postgresql/9.2.4 ...
警告：无法链接postgresql。取消链接...

错误：无法符号链接文件：
/usr/local/Cellar/postgresql/9.2.4/share/man/man7/WITH .7
/ usr / local / share / man / man7不可写入。您应该更改其
权限。

帮助请

注意：我已经为mavericks安装了命令行工具。

如果我使用自制软件卸载并尝试再次安装，得到这个错误：

==>注意事项

构建注释

如果PostgreSQL 9的构建失败并且您安装了版本8.x
，您可能需要先删除以前的版本。请参阅：

https://github.com/mxcl/homebrew/issues/issue/2510

创建/升级数据库

如果这是您的第一次安装，请创建一个数据库：initdb
/ usr / local / var / postgres -E utf8

要迁移$ b $之前的主要版本（9.2之前版本） b PostgreSQL，请参阅：

http://www.postgresql.org/docs/ 9.2 / static / upgrading.html

加载扩展

默认情况下，Homebrew会构建所有可用Contrib扩展。要从psql命令行查看所有可用扩展的
列表，请运行：

SELECT * FROM pg_available_extensions;

要加载任何扩展名，导航到所需的数据库
并运行：CREATE EXTENSION [扩展名];

例如，要加载当前数据库
run：CREATE EXTENSION tablefunc;

有关CREATE EXTENSION命令的更多信息，请参阅：

http://www.postgresql.org/docs/9.2/static/sql-createextension.html For
有关扩展程序的更多信息，请参阅：

http：// www。 postgresql.org/docs/9.2/static/contrib.html

其他

有些机器可能需要调配共享内存：

http://www.postgresql.org/docs/9.2/static/kernel-resources.html#SYSVIPC
安装postgres gem时，包括ARCHFLAGS建议：
ARCHFLAGS = - arch x86_64gem install pg

要安装gems而不使用sudo，请参阅Homebrew wiki。

要让launchd在登录时启动postgresql：
ln -sfv /usr/local/opt/postgresql/*.plist〜/ Library / LaunchAgents然后现在加载postgresql：
或者，如果您不需要
想要/需要launchctl，那么您可以运行：
pg_ctl -D / usr / local / var / launchgl load〜/ Library / LaunchAgents / homebrew.mxcl.postgresql.plist postgres -l /usr/local/var/postgres/server.log start警告：无法链接
postgresql。取消链接...错误： brew链接步骤未成功完成
该公式已构建，但未链接到/ usr / local
中再试一次`brew link postgresql'
==>总结

I'm trying to install the pg gem in order to work again with my rails projects. But I get this error:

Building native extensions. This could take a while... ERROR: Error installing pg: ERROR: Failed to build gem native extension.

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 * Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.

Gem files will remain installed in /Users/jeanosorio/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/gems/2.0.0/gems/pg-0.17.0 for inspection. Results logged to /Users/jeanosorio/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/gems/2.0.0/gems/pg-0.17.0/ext/gem_make.out

I tried everything I found on stackoverflow but I still get this error.

If I try to install postgresql using brew I get the following waring:

Warning: postgresql-9.2.4 already installed, it's just not linked

If I try to link

brew link postgresql Linking /usr/local/Cellar/postgresql/9.2.4... Warning: Could not link postgresql. Unlinking...

Error: Could not symlink file: /usr/local/Cellar/postgresql/9.2.4/share/man/man7/WITH.7 /usr/local/share/man/man7 is not writable. You should change its permissions.

Help Please

NOTE: I already installed the command line tools for mavericks.

If I uninstall using homebrew and try to install again, I get this error:

Build Notes

If builds of PostgreSQL 9 are failing and you have version 8.x installed, you may need to remove the previous version first. See:
https://github.com/mxcl/homebrew/issues/issue/2510

Create/Upgrade a Database

If this is your first install, create a database with: initdb /usr/local/var/postgres -E utf8

To migrate existing data from a previous major version (pre-9.2) of PostgreSQL, see:
http://www.postgresql.org/docs/9.2/static/upgrading.html

Loading Extensions

By default, Homebrew builds all available Contrib extensions. To see a list of all available extensions, from the psql command line, run:
SELECT * FROM pg_available_extensions;

To load any of the extension names, navigate to the desired database and run: CREATE EXTENSION [extension name];

For instance, to load the tablefunc extension in the current database, run: CREATE EXTENSION tablefunc;

For more information on the CREATE EXTENSION command, see:
http://www.postgresql.org/docs/9.2/static/sql-createextension.html For more information on extensions, see:
http://www.postgresql.org/docs/9.2/static/contrib.html

Other

Some machines may require provisioning of shared memory:
http://www.postgresql.org/docs/9.2/static/kernel-resources.html#SYSVIPC When installing the postgres gem, including ARCHFLAGS is recommended: ARCHFLAGS="-arch x86_64" gem install pg

To install gems without sudo, see the Homebrew wiki.

To have launchd start postgresql at login: ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents Then to load postgresql now: launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist Or, if you don't want/need launchctl, you can just run: pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start 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' ==> Summary
