मैं अजगर के लिए नया हूं। हाल ही में मुझे अजगर द्वारा लिखित एक प्रोजेक्ट मिला है और इसके लिए कुछ इंस्टॉलेशन की आवश्यकता है। मैं स्थापित करने के लिए नीचे कमांड चलाता हूं, लेकिन एक त्रुटि मिली।
# 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
मैंने Google पर खोजा और इस लिंक को ढूंढा http://stackoverflow.com/questions/28167987/python-pip-trouble-installing-from-requirements-txtलेकिन मुझे यह समझ में नहीं आया कि उस पोस्ट में इसका क्या समाधान है।
नीचे मेरी आवश्यकताएँ हैं।
# 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
क्या इस अजगर परियोजना में सभी आवश्यक निर्भरताएं स्थापित करने का एक आसान तरीका है?
EDIT1
नीचे से आउटपुट है pip3 install -r requirements.txt।
# pip3 install -r requirements.txt

मैंने पहले ही स्थापित कर लिया है, libfreetype6-devलेकिन पाइप कमांड अभी भी इस निर्भरता को गायब करने की रिपोर्ट करता है।
