问题描述

因此，我刚刚设置了我的Digital Ocean Drop（服务器），并一直在努力使该站点正常工作，但是我遇到了一个又一个错误。我终于找到了加载登录页面的网站（应该执行的操作），但是登录时出现了一个错误，提示您无法加载Argon2 Pass Hasher。我真的不知道问题出在哪里，因为在开发过程中一切正常。
这是错误：
/ accounts / login /
中的
  ValueError无法加载'Argon2PasswordHasher'算法库：没有名为argon2 
   
 
 这是我的设置：

请帮忙，这个问题似乎很具体，所以我无法在其中找到很多... 
解决方案
根据：
 
 
 这很简单，我只需要运行 pip install django [argon2] 在服务器上，相当于 python -m pip install argon2-cffi 。
 
So I have just setup my Digital Ocean droplet (server) and have been working to get this site to work, however I have been coming across error after error. I finally got the site to load the login page (which is what should happen), but when I login I get an error that Argon2 Pass Hasher couldn't load. I really have no idea what the problem is, as everything was working perfectly while in development.
Here is the error:
ValueError at /accounts/login/
Couldn't load 'Argon2PasswordHasher' algorithm library: No module named argon2
Here are my settings:

 解决方案 
According to the documentation:
It was simple, I just had to run pip install django[argon2] on the server, which is equivalent to python -m pip install argon2-cffi.
