導入錯誤：無法導入名稱memoize的1.8-1.9

Question

我有一個錯誤：

Invalid template library specified. ImportError raised when trying to load 'crispy_forms.templatetags.crispy_forms_field': cannot import name memoize

下調至1.8並沒有幫助像here

有人在Ubuntu 14.04的工作，但在Win10不起作用

• Python2.7
• Django1.9
• django的鉻ISPY-形式== 1.4.0

脆皮形式1.4是過時的。

如果你看看crispy forms changelog，你可以看到何時增加了對不同Django版本的兼容性。

對於Django 1.8，您需要安裝酥脆的表格1.5或更高版本。

對於Django 1.9，您需要安裝脆皮形式1.6或更高版本。
