IPython 3.9, uyifaka njani le nguqulo kwi-Ubuntu 20.04

Kwinqaku elilandelayo siza kujonga Singayifaka njani i-python 3.9 kwi-Ubuntu 20.04. Kwimeko apho kusekho umntu ongaziyo, iPython yenye yezona lwimi zidumileyo emhlabeni. Iyahluka kwaye isetyenziselwa ukwenza zonke iintlobo zezicelo, ukusuka kwizikripthi ezilula ukuya kwii-algorithms ezintsonkothileyo. Ukuba lula ukuyiqonda, ukufunda nokubala Is syntax elula, IPython lukhetho oludumileyo kubo bobabini abaqalayo kunye nabaphuhlisi abanamava.

IPython 3.9 lolona hlobo lukhulu lokugqibela olufumanekayo kolu lwimi. Ibandakanya izinto ezininzi ezintsha ezinje; abaqhubi abatsha abayalelayo, iindlela zentsontelo yokususa isimaphambili kunye nezimamva, imisebenzi emitsha ye-str, inkxaso yendawo ye-IANA, kunye nokunye. Zonke iindaba kunokuboniswana ngazo ku khupha inqaku kule nguqulo IPython.

Ukufakwa kwePython 3.9

Kule migca ilandelayo, siza kubona Iindlela ezimbini zokufaka iPython 3.9 kwi-Ubuntu 20.04. Inketho yokuqala iya kuba kukufaka ipakeji kwi-Deadsnakes PPA, kwaye eyesibini iya kuba kukwakha iPython 3.9 kwikhowudi yemithombo esinokuyikhuphela kwiwebhusayithi yePython.

Kunye APT

Ukufaka iPython 3.9 ku-Ubuntu ngokulula yinkqubo elula, enokuthi yenziwe ngokukhawuleza okukhulu. Ukuqala sivula i-terminal (Ctrl + Alt + T) kwaye siza kuthi Hlaziya uluhlu lweephakeji ezikhoyo ezivela kwindawo yokugcina izinto:

sudo apt update

Ngoku siza kuya faka iimfuno eziyimfuneko, ukuba asikazifaki ngoku:

sudo apt install software-properties-common

Into elandelayo esiza kuyenza yile yongeza i-PPA kuluhlu lwemithombo kwinkqubo yethu:

sudo add-apt-repository ppa:deadsnakes/ppa

Emva kokongeza indawo yokugcina izinto, ku-Ubuntu 20.04 uluhlu lweephakeji ezikhoyo ziya kuhlaziywa. Nje ukuba indawo yokugcina inikwe amandla kwaye yonke into ihlaziyiwe, sinokuqhubeka faka i-python 3.9 ukubaleka kwisiphelo esinye:

sudo apt install python3.9

Emva kofakelo, Siza kuqinisekisa ukuba ufakelo lwaluchanekile Ukuchwetheza kwisiphelo sendlela:

python3.9 --version

Ukuba kwiscreen sibona umyalezo ofana nalowo uboniswe kwiscreen esidlulileyo, iPython 3.9 iya kufakwa ku-Ubuntu kwaye sinokuqala ukuyisebenzisa.

Isuka kumthombo

Ukuqulunqa iPython ukusuka kumthombo kuya kusivumela ukuba sifake ingxelo yokugqibela yePython kwaye senze ngokwezifiso iindlela zokuhlanganisa. Nangona kunjalo, ayizukuvumela ukuba sigcine ukufakwa kwePython ngomphathi wephakheji efanelekileyo. Kule migca ilandelayo siza kubona indlela yokuhlanganisa iPython 3.9 evela kumthombo.

Ukuqala siza kuthi faka ukuxhomekeka okuyimfuneko. Kwisiphelo (Ctrl + Alt + T) kuya kufuneka sibhale:

sudo apt update; sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev wget libbz2-dev

Ukukhuphela

Ngoku masenze khuphela ikhowudi yemvelaphi yohlobo lwamva nje kwifayile ye- iphepha lokukhuphela IPython ngewget. Kwisiphelo (Ctrl + Alt + T) singasebenzisa lo myalelo:

wget https://www.python.org/ftp/python/3.9.0/Python-3.9.0.tgz

Nje ukuba ukhuphelo lugqityiwe, kuya kufuneka khupha ifayile ecinezelweyo nge-gzip. Siza kukuphumeza oku ngokubhala:

tar -xf Python-3.9.0.tgz

Siyaqhubeka nokutshintshela kulawulo lwePython esele yenziwe. Nje ukuba singene ngaphakathi, siya kuthi sebenzisa iskripthi sokuseta. Oku kuyakwenza uthotho lweetsheki ukuqinisekisa ukuba zonke izixhomekeki zikhona kwinkqubo yethu:

cd Python-3.9.0
./configure --enable-optimizations

Ukudityaniswa

Xa umyalelo wangaphambili ugqityiwe, siya kuthi qala inkqubo yokwakha yePython 3.9:

make -j 12

Xa inkqubo yokwakha igqityiwe, sinako faka ipython Ukuchwetheza kwisiphelo esinye:

sudo make altinstall

Yenza ufakelo lungabhala ngaphezulu okanye ligqume i-python3 yokubini. Kulo python iphepha Ndicebisa ukuba wenze i-altinstall endaweni yokwenza ufakelo, kuba ifaka kuphela yenza_prefix / bin / pythonversion.

Ukugqitywa, iPython 3.9 iya kufakwa kwaye ilungele ukusetyenziswa. Kuba jonga ufakelo oluyimpumeleloSinokubhala kwisiphelo sendlela:

python3.9 --version

Kule migca sibonile indlela abasebenzisi be-Ubuntu 20.04 abanokuyifaka ngayo le nguqulo yePython ngendlela elula. Ngoku nabani na unokuqala ukuphuhlisa iiprojekthi zabo ngePython 3.9. Ukuba ufuna ukunceda ukuqala ngePython, olu lwimi lubonelela nge maxwebhu kwiwebhusayithi yeprojekthi.
