pg gem 很顽固，所以我无法在新计算机上加载我的应用程序。似乎有多个问题，无法找到 pg_config 和 extconf.rb
#psql working...
psql (9.2.1)
Type "help" for help.
nd =>
\q
$ pg_config:
#adding the path to bashrc...
$ nano .bashrc
PATH=/usr/pgsql-9.2/bin:$PATH
#seems to work...
pg_config: /usr/pgsql-9.2/bin/pg_config
$ sudo gem install pg
#but i get the same errors...
Building native extensions. This could take a while...
.......
ERROR: Error installing pg:
ERROR: Failed to build gem native extension.
/usr/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 ***
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.
有没有 linux 人处理过这个问题？
最佳答案
解决了
$ yum install /usr/include/libpq-fe.h
