django 1.10升級到1.11時出現的錯誤怎么解決？

Question

django從1.10升級到1.11后， manage.py命令無法使用。 有太多的錯誤，我什至不知道從哪里開始，從哪里尋找錯誤的原因。 我將不勝感激任何幫助。

我粘貼下面的所有錯誤。

我已經使用命令pip list --outdated --format = freeze | grep -v '^ \\ - e' | cut -d = -f 1 | xargs -n1 pip install -U升級了所有依賴項pip list --outdated --format = freeze | grep -v '^ \\ - e' | cut -d = -f 1 | xargs -n1 pip install -U pip list --outdated --format = freeze | grep -v '^ \\ - e' | cut -d = -f 1 | xargs -n1 pip install -U ，我在這里找到的：在此處輸入鏈接描述

現在錯誤的數量已經減少到幾個。 我把它們貼在下面。

您的pip install -U命令已將 easy-thumbnails 升級到2.7.0 ，但該版本放棄了對 Django 1.11.X 的支持

在 2.5.0 中添加了對 Django 1.11 的支持，因此 2.5.0 或 2.6.0 應該可以工作（取決於其他要求）。 您可以使用以下命令安裝 2.6：

pip install --upgrade "easy-thumbnails<2.7.0"
