第 613 行of this django code is where the import of PIL is

我可以进入 heroku bash 并导入它（我猜它没有安装）

所以我做了一些事情，我“重新启动所有测功机”，然后我尝试再次上传图像。同样的错误

所以我退出 heroku bash，重新进入并

我的 Pillow 不知何故被卸载了。为什么会这样

【问题讨论】：

你的requirements.txt有吗？
我实际上只是想通了-我使用的是heroku-django-template，它有一个Pipfile（新的pipping方式），b/c Pillow不在我的Pipfile中，每次我重新启动heroku，它会擦掉。我在我的 Pipfile 中添加了 Pillow = "*" 并且现在可以使用
