An error occurred while installing pg (0.14.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.14.1'` succeeds before bundling.

나는 만든다 $ gem install pg -v '0.14.1' 만 이것은 도움이 아니다

답변

그냥 만들어

$ sudo apt-get install libpq-dev


답변

이것은 pg gem을 설치하려고 할 때 ‘libpq-fe.h 헤더를 찾을 수 없습니다.

환경에 따라 :

  • 맥: brew install postgresql
  • 우분투 :sudo apt-get install libpq-dev
  • RHEL :yum install postgresql-devel

그런 다음 gem install pg다시 실행


답변

이 시도:

  1. 양조 설치 postgresql
  2. gem 설치 pg
  3. 번들 설치


답변

Fedora / RHEL 시스템에서 이것은 트릭을 수행했습니다.

sudo yum install libpqxx-devel


답변

  • SO : 우분투
  • 언어 프로그래밍 : C

$ sudo apt-get install libpq-dev

제 경우에는 디렉토리 경로를 잘못 입력했습니다. 그래서:

에서: gcc -o lib_version lib_version.c -I/usr/include/postgresql -lpq -std=c99

에: gcc -o lib_version lib_version.c -I /usr/include/postgresql -lpq -std=c99

답변

Mac OS X에서는 다음과 같이 실행합니다.

gem install pg -- --with-pg-config=***/path/to/pg_config***

***/path/to/pg_config*** pg_config의 경로입니다.


답변

Amazon Linux (AWS)의 경우 :

sudo yum install postgresql-devel

그런 다음 명령을 다시 실행하십시오.
