Question

我在Windows 10中使用Python 3.7.0a2和Django（2,0,2，＆＃39; final＆＃39;，0）。当我正在迁移我的项目时，我收到以下错误：

ERRORS:
accounts.UserProfile.image: (fields.E210) Cannot use ImageField because Pillow is not installed.
        HINT: Get Pillow at https://pypi.python.org/pypi/Pillow or run command "pip install Pillow".

然后我运行了'pip install Pillow＆＃39;命令，我收到以下错误：

  During handling of the above exception, another exception occurred:

如何安装枕头？

Answer 1

枕头需要在Windows上编译。 #include <iostream> #include <iomanip> int main() { std::cout << std::setw(15) << std::setfill('-') << "PRODUCT" << std::setw(15) << std::setfill('-') << "AMOUNT" << std::endl; std::cout << std::setw(15) << std::setfill('-') << "Brush" << std::setw(15) << std::setfill('-') << 10 << std::endl; std::cout << std::setw(15) << std::setfill('-') << "Paste" << std::setw(15) << std::setfill('-') << 8 << std::endl << std::endl; std::cout << std::setw(15) << std::left << std::setfill('-') << "PRODUCT" << std::setw(15) << std::left << std::setfill('-') << "AMOUNT" << std::endl; std::cout << std::setw(15) << std::left << std::setfill('-') << "Brush" << std::setw(15) << std::left << std::setfill('-') << 10 << std::endl; std::cout << std::setw(15) << std::left << std::setfill('-') << "Paste" << std::setw(15) << std::left << std::setfill('-') << 8 << std::endl << std::endl; std::cout << std::setw(15) << std::right << std::setfill('-') << "PRODUCT" << std::setw(15) << std::right << std::setfill('-') << "AMOUNT" << std::endl; std::cout << std::setw(15) << std::right << std::setfill('-') << "Brush" << std::setw(15) << std::right << std::setfill('-') << 10 << std::endl; std::cout << std::setw(15) << std::right << std::setfill('-') << "Paste" << std::setw(15) << std::right << std::setfill('-') << 8 << std::endl << std::endl; return 0; }尝试使用预编译版本，如果失败 - 它会尝试在本地编译它。

你正在使用尚未发布的Python 3.7，我怀疑枕头人没有准备好预编译的二进制文件。

最简单的解决方案是降级到Python 3.6。否则，您需要安装编译Pillow所需的一切。

Answer 2

here提供了用于python 3.7的Pillow的预编译版本。

在下载的车轮上运行pip install对我来说很有效。

Answer 3

尝试像下面一样安装Pillow（如果您使用的是Python3）：

pip3 install pillow

这个:(如果您使用的是Python2）：

pip install pillow

Answer 4

对于带有python3.7的最新Anaconda，可提供枕头。使用以下命令安装它：

conda install pillow

然后，停用当前的环境，然后再次激活环境，它应该可以工作。（此步骤对于使其有效很重要）

Answer 5

也许有人会有用。

只有将某些软件包更新为某些版本后，我才能在虚拟环境中安装软件包 Pillow （7.0.0）。

我将软件包setuptools更新到了最新版本（当时是44.0.0）

并将软件包pip更新为19.2.3。

作为参考，我使用了： Python 3.8.0， Django 2.2.8， Virtualenv 16.7.9， Windows 10 SL x64

无法在Windows上的Python 3.7.0a上安装Pillow
