异常值：在 Django 中没有名为“PIL”的模块

Question

Django 版本：3.1.6 Python 版本：3.6.9

我正在尝试使用 django 管理页面中的 ImageField 来上传图像。当我尝试从我的 NGinx/Gunicorn 服务器上传它时，我收到了这个错误。但是，当我使用同一服务器上的 manage.py runserver 0:8000 从端口 8000 运行它时，它可以工作。我不明白这个错误。我已经安装了 Pillow。

Answer 1

尝试使用这些命令：-

1)。如果您使用的是 Unix，请运行。

python -m pip install -U pip

2). 此命令用于安装或升级设置工具。 （安装工具默认安装，但你应该升级它）

pip install setuptools

3)。现在，卸载并重新安装Pillow。

用于卸载

pip 卸载枕头

现在安装

pip 安装枕头

Answer 2

Pil 目前在 django 中不可用。 使用它的继任者

pip 安装枕头

正如你所说，你已经安装了枕头，那么问题一定是 pip ，升级 pip 然后试试它是否有效。

pip install --upgrade pip

pip 的版本确实决定了如何解压缩包，这最终决定了模块是否正确加载。 然后导入图像并希望它有效。

Answer 3

Django 没有预装 Pillow。 要安装，只需运行：

python3 -m pip install --upgrade Pillow

安装或升级。
