Kutheni Impazamo: i-pg_config executable ayifumaneki?
Ukubethwa yi- impazamo: i-pg_config esebenzisekayo ayifumaneki ngexesha lokufaka i-pip psycopg2 kwi-CI? Le ngxaki iqhelekileyo ithetha ukuba i-pg_config binary, efunekayo ukuze kuhlanganiswe iipakeji zePython ezinxulumene nePostgreSQL, ayikho. Kule khokelo, uza kufunda indlela yokulungisa i-pg_config executable not found error ngokukhuselekileyo kwi-local dev, iDocker, kunye CI/CD indawo.
Yintoni ethethwa yi-Error: pg_config executable not found?
Umyalezo wemposiso i-pg_config esebenzisekayo ayifumaneki kuthetha izixhobo zokwakha zePython (ezifana i-pip, i-setuptools, okanye ukwakha) andikwazi ukuyifumana i-pg_config usetyenziso kwinkqubo yakho. Le binary yinxalenye yeelayibrari zophuhliso lwePostgreSQL kwaye idlala indima ebalulekileyo ngexesha lokuhlanganiswa kwephakheji.
Ngokukodwa, i-pg_config uxelela abahlanganisi apho banokufumana khona ii-headers zePostgreSQL, iilayibrari, kunye nokwakha iiflegi, ulwazi olufunekayo kwiiphakheji zePython ezidumileyo ezinezandiso ze-C ezifana i-psycopg2, i-pgvector, okanye i-timescaledb-python. Xa ingekho, izakhiwo ziyasilela ngemiyalezo efana nale:
Building wheel for psycopg2 (setup.py) ... error error: pg_config executable not found Le ngxaki ayiphelelanga kwi-OS enye okanye kwindawo enye; ibonakala kwiikhonteyina zeDocker, i-macOS, iLinux, kwanee-Windows setups ngaphandle kwezixhobo zophuhliso zePostgreSQL ezifakiweyo.
Isizathu Sokuba Kwenzeka Oku (Kwiindawo Ezihlukeneyo)
