我刚刚将我的应用程序部署到Heroku,并且在打开应用程序时遇到错误,它说:“ModuleNotFoundError:没有名为'crispy_forms'的模块”,而且MultiSelectField也是如此 .
我试图在平台的控制台中安装这些软件包,但它似乎没有任何效果,每次运行'heroku run pip freeze'时,我都会得到相同的软件包 .
我试图在运行以下命令的本地控制台中执行此操作:
heroku run bash
pip install django-crispy-forms
pip install django-multiselectfield
pip freeze # To check if the packages where installed
然后我得到一切似乎都很好,django-crispy-forms和django-multiselectfield出现在'pip freeze'命令的包列表中,但是当我在平台上检查时,更新不存在 .
如下所示,我在根文件夹中添加了“requirements.txt”文件,其中包含Pipfile,Procfile .
使用代码pip freeze> requirements.txt添加了“requirements.txt”文件:

不要手动尝试安装软件包 . 您应该创建一个requirements.txt文件并将其提交给git,然后Heroku将自动在部署时安装这些软件包 .
你所做的不起作用的原因是
heroku run bash
- 或任何命令 - 创造了一个全新的dyno;你在那里安装了这些包,但是当你退出并且其他dynos没有受到影响时,dyno会被立即杀死 .https://devcenter.heroku.com/articles/deploying-python
您通过
heroku run bash
所做的更改不会持久 . 一旦你退出bash,dyno会立即终止 .我建议您在根文件夹中创建一个需要_687697的requirements.txt,或者在Pipfile中提及依赖项 .
在Pipfile中添加它
