"Read-thecs" derlemesi, "pip._internal.index" klasöründen "PackageFinder" adını içe aktaramıyor "ile başarısız oluyor."

Sphinx dokümanlarının read-the-docs'ta derlemesi aşağıdaki hatayla başarısız olur (aşağıdaki tam günlük):

ImportError: cannot import name 'PackageFinder' from 'pip._internal.index' (/home/docs/checkouts/readthedocs.org/user_builds/cascade-python/envs/latest/lib/python3.7/site-packages/pip/_internal/index/__init__.py)

Yanlış bir şey mi yaptım yoksa bu dokümanlar için bir hata mı?

Sfenks belgelerinin yerel bir yapısı iyi çalışır.

Dokümanları okurken hata günlüğünü tamamla:

Sorun ve düzeltme salt-docs açıklanmıştır sorunu # 6554 ( https://github.com/readthedocs/readthedocs.org/issues/6554 ):

Şu anda tüm yapılar başarısız oluyor çünkü 20.0 pipine otomatik yükseltme (# 4823'ten beri) buggy (pypa / pip # 7620'ye bakınız). Şimdi başkaları için sorunu çözmüş gibi görünen 20.0.1 sürümü var ... ama readthoclarımı da .1 sürümüne yükseltmeye nasıl zorlayabilirim?

Çözüm, oluşturma ortamını şu şekilde silmektir (bu, https://docs.readthedocs.io/en/stable/guides/wipe-environment.html adresinden alınır ):

• Dokümanları okumak için giriş yapın
• Sürümlere Git
• Sayfanın sağ tarafında silmek istediğiniz sürümün Düzenle düğmesini tıklayın
• Sayfanın alt kısmına gidin ve "Kaydet" düğmesinin yanındaki sil bağlantısını tıklayın
• Artık sürümü yeni bir oluşturma ortamıyla yeniden oluşturabilirsiniz!

Bu düzeltme benim için çalıştı (ancak 26 Ocak 2020'den itibaren her yapı için çevreyi silmeniz gerekiyor - aşağıdaki Grimmy'nin yorumuna bakın).
