python 프로젝트에 모든 종속성을 설치하기 위해 requirements.txt를 사용하는 방법

---

나는 파이썬을 처음 사용합니다. 최근에 나는 파이썬으로 작성된 프로젝트를 얻었고 약간의 설치가 필요합니다. 아래 명령을 실행하여 설치했지만 오류가 발생했습니다.

# pip install requirements.txt 
Collecting requirements.txt
  Could not find a version that satisfies the requirement requirements.txt (from versions: )
No matching distribution found for requirements.txt

Google에서 검색하여 이 링크를 찾았 http://stackoverflow.com/questions/28167987/python-pip-trouble-installing-from-requirements-txt지만 해당 게시물의 솔루션이 무엇인지 잘 모르겠습니다.

아래는 내 requirements.txt 파일입니다.

# cat requirements.txt 
ordereddict==1.1
argparse==1.2.1
python-dateutil==2.2
matplotlib==1.3.1
nose==1.3.0
numpy==1.8.0
pymongo==3.3.0
psutil>=2.0

이 python 프로젝트에 필요한 모든 종속성을 쉽게 설치하는 방법이 있습니까?

아래는 의 출력입니다 pip3 install -r requirements.txt.

# pip3 install -r requirements.txt

Linux OS를 사용하는 경우:

1. 제거 matplotlib==1.3.1에서requirements.txt
2. 로 설치해 보세요 sudo apt-get install python-matplotlib
3. 실행 pip install -r requirements.txt(Python 2) 또는 pip3 install -r requirements.txt(Python 3)
4. pip freeze > requirements.txt

Windows OS를 사용하는 경우:

1. python -m pip install -U pip setuptools
2. python -m pip install matplotlib

pip install -r requirements.txt ~을위한 python 2.x

pip3 install -r requirements.txt for python 3.x (in case multiple versions are installed)

---

python -m pip install -r requirements.txt

(Taken from my comment)

pip won't handle system level dependencies. You'll have to apt-get install libfreetype6-dev before continuing. (It even says so right in your output. Try skimming over it for such errors next time, usually build outputs are very detailed)
