質問
私はRailsアプリに取り組んでいます。
PostgreSQL-9.1.2-1-osx.dmgを使用したPostgreSQLがインストールされました
gem。
それから私がrake db:create
を実行したとき
次のエラーを取得する -
dlopen(/users/sathishvc/.rvm/gems/ruby-1.9.3-head@knome-vivious/gems/pg-0.12.2 / lib/pg_ext.bundle、 9):ライブラリがロードされていません:/usr/local/lib/libpq.5.4.dylib
/usr/local/lib/libpq.5.4.dylib
が存在するかどうかをチェックします。
だから、それはシステムの他の場所に存在するべきです、または私がこれに他のソフトウェアをインストールする必要があるならば、私は知りません。誰かを助言してください?

Some time after I posted this question, I found that libpq.5.4.dylib
resides in /Library/PostgreSQL/9.1/lib/
.
So, I created the following link:
lrwxr-xr-x 1 sathishvc admin 43 Jan 28 23:40 /usr/local/lib/libpq.5.4.dylib -> /Library/PostgreSQL/9.1/lib/libpq.5.4.dylib
.
This solved the problem then.
他のヒント
if you have upgraded PostgreSQL with homebrew (brew update && brew upgrade), then simply uninstall the pg gem:
gem uninstall pg
bundle install
and the path will be corrected for you. No need to uninstall the whole PostgreSQL cluster.
I was running into this issue after switching over to the PostgresApp and removing the existing PostgreSQL version via
brew remove postgres
I ultimately solved the problem by re-installing PostgreSQL via
brew install postgres
I was able to retain the use of the PostgresApp by adding the following to my .bash_profile
export PATH="/Applications/Postgres.app/Contents/MacOS/bin:/usr/local/bin:$PATH"
You can also try running:
brew doctor
As it alerted me to this as well as some additional errors.
This error was also affecting my ability to use the Paperclip gem as it was causing ImageMagick to fail with the same error.
(Using OS X 10.8.2)
In my case, uninstalling /reinstalling gem didn't help. But I added the PostgreSQL library path to $DYLD_LIBRARY_PATH
environment variable in my ~/.bash_profile
:
export DYLD_LIBRARY_PATH=/Library/PostgreSQL/9.3/lib:$DYLD_LIBRARY_PATH
If you also have MySQL installed, this line can look like:
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:/Library/PostgreSQL/9.3/lib:$DYLD_LIBRARY_PATH
Of course pay attention to version number in the PostgreSQL path, at the time of this writing it is 9.3. I'm using RVM, Ruby 2.0.0, pg gem 0.17.0, on Mac OS X 10.6.
Try brew prune
and then reinstall
this is not a direct answer to the question but can arise frequently
Two additional cases that might be of interest if you have upgraded PostgreSQL with homebrew:
- you have proceeded in the past to some pruning of gem versions
- your application is older and cannot take a recent version of pg (I have a rails 2 app failing with pg 0.17 and nearly killing the server: the mkmr.log increases exponentially ...try 200GB! )
you may actually have numerous versions of pg to rely upon
when you run
gem uninstall pg
if you have more than one version, the system will ask which version you wish to delete. But that list may be useful to you! As an alternative to awenkhh's answer you may stop there and reset your gems to an acceptable version
