Esu labai naujas "Python" naudotojas ir bandau > pip install linkchecker
"Windows 7" sistemoje. Keletas pastabų:
> pip install scrapy
taip pat sukelia SSL klaidą.python
ir pip
nebuvo prieinami iš komandinės eilutės.> pip search linkchecker
veikia. Galbūt taip yra todėl, kad pip search netikrina svetainės' SSL sertifikato.Štai mano pip.log turinys po to, kai paleidau pip install linkchecker
:

Naudodami šį parametrą galite nurodyti cert:
pip --cert /etc/ssl/certs/FOO_Root_CA.pem install linkchecker
Žr: Docs » Reference Guide » pip
Jei nurodžius jūsų įmonės'šakninį sertifikatą nepavyksta'i, gal tiks cURL: http://curl.haxx.se/ca/cacert.pem
Turite naudoti PEM, o ne CRT failą. Jei turite CRT failą, turėsite konvertuoti failą į PEM Komentaruose yra pranešimų, kad dabar tai veikia su CRT failu, bet aš to nepatikrinau.
Taip pat patikrinkite: SSL Cert Verification.
Šią problemą išsprendžiau pašalindamas savo pip ir įdiegdamas senesnę pip versiją: https://pypi.python.org/pypi/pip/1.2.1.
