「類型錯誤：hashpw（）參數1必須海峽，而不是字節」試圖註冊燒瓶安全用戶時

我試圖創建一個使用Enferno framework小燒瓶應用程序，但是當我嘗試註冊用戶我得到一個似乎由passlib庫生成的錯誤。我無法理解這是我做過的事情還是圖書館本身出現錯誤。「類型錯誤：hashpw（）參數1必須海峽，而不是字節」試圖註冊燒瓶安全用戶時

以下是完整回溯：

您是否在使用Python 3，我建議您可以使用flask-security提交bugreport。 – Timo

看起來這可能源於passlib 1.6.2及更早版本中的已知錯誤。更新到passlib 1.6.4（2015-7-25發佈）應該可以解決這個問題。 –

我只是碰到了這一點。原來，我在我的virtualenv中安裝了bcrypt和python-bcrypt。 passlib.hash.bcrypt查看bcrypt上的哪個版本。通過刪除python-bcrypt，我能夠停止拋出這個錯誤。

謝謝，這也幫助我;）雖然我不得不用bcrypt（bcrypt，python-bcrypt和flask-bcrypt）卸載所有東西， – anks
