पाइप त्रुटि: कोई फोरट्रान संकलक नहीं मिला, लेकिन संकलक पहले से मौजूद है

0

मैं पाइप का उपयोग करके PyAstronomy के लिए एक बाहरी पुस्तकालय स्थापित करने की कोशिश कर रहा हूं:

pip install PyAstronomy_ext

मैं एनाकोंडा कमांड प्रॉम्प्ट के माध्यम से ऐसा करता हूं। पहली बार जब मैंने कमांड को चलाया तो निम्नलिखित त्रुटियाँ सामने आईं:

building 'PyAstronomy_ext.forTrans.occultnl' extension
error: extension 'PyAstronomy_ext.forTrans.occultnl' has Fortran sources but no Fortran compiler found

Failed building wheel for PyAstronomy-ext

तथा

Command "c:\users\matte\anaconda3\python.exe -u -c "import setuptools, tokenize;__file__='C:\\Users\\matte\\AppData\\Local\\Temp\\pip-install-5pkiwi34\\PyAstronomy-ext\\setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record C:\Users\matte\AppData\Local\Temp\pip-record-bok3jklv\install-record.txt --single-version-externally-managed --compile" failed with error code 1 in C:\Users\matte\AppData\Local\Temp\pip-install-5pkiwi34\PyAstronomy-ext\

इसलिए मैंने इंटरनेट पर जाँच की और इस विषय को पाया । मैंने MinGW स्थापित किया और सभी फोरट्रान संबंधित पैकेज डाउनलोड किए, और यह सुनिश्चित करने के लिए कि मैंने एक परीक्षण स्क्रिप्ट भी लिखी है और इसे gFortran का उपयोग करके संकलित किया है, और यह ठीक काम किया है।

जब मैंने इंस्टॉलेशन को फिर से चलाने का प्रयास किया तो वही त्रुटियां पॉप अप हुईं।

इस सवाल का जवाब भी यह उल्लेख है:

स्थापना के बाद, सिस्टम PATH को इसके बाइनरी में पथ जोड़ें।

लेकिन मैं यह नहीं समझ सकता कि इसका क्या मतलब है, मैंने इंस्टॉलेशन कमांड चलाने की कोशिश की, C:\MinGW\binलेकिन वही त्रुटि होती है।

यदि आपको संपूर्ण कंसोल संवाद की आवश्यकता है जिसमें त्रुटियां हैं:

संपादित करें: मैं कुछ खुदाई करके समस्या को हल करने में सक्षम था, मुझे निम्नलिखित के साथ एक distutils.cfgफाइल लिखना था C:\...\Anaconda3\Lib\distutils:

[build]           
compiler=mingw32

और फिर एनाकोंडा प्रॉम्प्ट से निम्नलिखित कमांड चलाएं:

conda install libpython
conda install -c msys2 m2w64-toolchain

इसके बाद pip install PyAstronomy_extपूरी तरह से काम किया।

अगर किसी को भी इस समस्या का सामना करना पड़ रहा है तो मैं इसे यहाँ छोड़ रहा हूँ।
