psycopg2 설치 오류, -lssl에 대한 라이브러리를 찾을 수 없음

"sudo pip install psycopg2"를 실행하면 다음과 같은 출력이 나타납니다.

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

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

그리고 마지막에는 다음과 같이 말합니다.

ld: library not found for -lssl

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

---

양조 설치 (또는 업그레이드) openssl을 실행하면 다음과 같은 결과가 나타납니다.

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

누구든지 나를 도울 수 있습니까?

macOS Sierra 10.12에서 이에 대한 솔루션을 찾는 모든 사람 : 명령 줄 도구를 설치하여이 문제를 해결했습니다.

xcode-select --install

그 후에 pip install psycopg2작동합니다.

그렇지 않은 경우 brew의 openssl에 대해 링크를 시도 할 수도 있습니다.

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

brew를 통해 설치된 openssl과 함께. (가) 있습니다 brew link openssl --force더 이상 작동하지 않습니다

$ brew link openssl --force                                                                                 17.5s
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

@macho가 여전히 작동하지 않으면 아래에서 지적했듯이 --no-cachepip 옵션 을 사용해야 할 수도 있습니다.

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

---

실행할 때 brew link openssl다음 메시지가 나타납니다.

$ brew link openssl
Warning: Refusing to link: openssl

이 조언에 따라 pip사용해야 하는 명령 은 다음과 같습니다 .

$ pip install -r requirements.txt --global-option=build_ext --global-option="-I/usr/local/opt/openssl/include" --global-option="-L/usr/local/opt/openssl/lib"

Brew ( brew install openssl) 에서 OpenSSL을 설치했습니다.

다음은 나를 위해 일했습니다.

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

---

나를 위해 일한 것은 openssl을 연결하는 명령에 제공된 힌트였습니다.

$ brew link openssl
Warning: Refusing to link macOS-provided software: openssl
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"

$ pip install psycopg2

mojave에서 나는 이것을 .bash_profile에 추가했습니다.

export PATH="/usr/local/opt/openssl/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/curl/lib -L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/curl/include -I/user/local/opt/openssl/include"

그런 다음 파이썬 3.7.4 virtualenv에 psycopg 2.8.3을 설치할 수있었습니다.

xcode 및 명령 줄 도구를 다시 설치 한 후.

위의 모든 답변이 도움이되었습니다!

---

최근에 Virtualenv에 Python 3.7을 설치 한 High Sierra에서이 문제가 발생했습니다.

해결책은 psycopg2의 최신 버전을 사용하는 것입니다. 버전 2.7.7은 작동했지만 2.7.1은 작동하지 않았습니다.

---

Using Fish, the following two commands solved this issue for me after install OpenSSL using Homebrew.

set -gx LDFLAGS "-L/usr/local/opt/openssl/lib"
set -gx CPPFLAGS "-I/usr/local/opt/openssl/include"

Use brew info openssl to get up-to-date info.

---

Instead of installing psycopg2, install psycopg2-binary, from the same authors:

pip install psycopg2-binary

This is what the documentation says about this PyPI package:

You can [...] obtain a stand-alone package, not requiring a compiler or external libraries, by installing the psycopg2-binary package from PyPI:

$ pip install psycopg2-binary

The binary package is a practical choice for development and testing but in production it is advised to use the package built from sources.

---

I was having this issue on Mojave. Mojave does not create a /usr/include directory, which psycopg2 needs to install. This was not obvious. I found the solution here: How to update Xcode from command line, which references: https://forums.developer.apple.com/thread/104296

This's the problem of new macOs version, where pip cannot install cryptography. What fixed my problem is to provide the env to the install command:

brew install openssl
env LDFLAGS="-L$(brew --prefix openssl)/lib" CFLAGS="-I$(brew --prefix openssl)/include" <YOUR COMMAND HERE>

You can replace <YOUR COMMAND HERE> with pip install cryptography, or pip install <SOMETHING THAT REQUIRES cryptography> for example.

---

I've managed to fix it by using:

brew unlink openssl && brew link openssl --force

I am not sure how this differs from the brew uninstall/upgrades that I did on OpenSSL in prior attempts I've made. My assumption is that these operations left some of the "faulty" shared libraries which were preventing this from working. Note that this also fixed issues with installing python cryptography module.
