[python] psycopg2 설치 오류, -lssl에 대한 라이브러리를 찾을 수 없음

난 달린다

sudo pip install psycopg2

다음과 같은 출력을 얻습니다.

cc -DNDEBUG -g -fwrapv -Os .....
.....
cc -DNDEBUG -g -fwrapv -Os .....
.....

그리고 마지막에는 다음과 같이 말합니다.

ld: library not found for -lssl

clang: error: linker command failed with exit code 1 (use -v to see invocation)

error: command 'cc' failed with exit status 1

easy_install을 실행 하거나 소스 에서 수행하면 끝에 동일한 오류가 발생합니다 (-lssl에 대한 라이브러리를 찾을 수 없음).

brew install (또는 업그레이드) openssl을 실행하면 아래와 같은 결과가 나옵니다.

$ brew upgrade openssl
Error: openssl-1.0.1h already installed

누구든지 나를 도울 수 있습니까?

Warning: Refusing to link: openssl
Linking keg-only openssl means you may end up linking against the insecure,
deprecated system OpenSSL while using the headers from Homebrew's openssl.
Instead, pass the full include/library paths to your compiler e.g.:
  -I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib

env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip --no-cache install psycopg2

export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
pip install psycopg2

If you need to have openssl first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.zshrc

For compilers to find openssl you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl/include"

$ export LDFLAGS="-L/usr/local/opt/openssl/lib"
$ export CPPFLAGS="-I/usr/local/opt/openssl/include"
