Raspberry Pi 3 上的 Django CMS 失败

Question

今天我尝试在我的 Raspberry pi 上安装 django CMS 一段时间，但它不起作用。我安装了一个新的“RASPBIAN STRETCH LITE”，然后我通过 ssh 连接输入了以下命令：

sudo wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py
sudo pip install Django==1.10
sudo pip install virtualenv
cd /srv
sudo mkdir django_cms
cd django_cms
sudo virtualenv env
source env/bin/activate
sudo pip install --upgrade pip
sudo pip install djangocms-installer
sudo mkdir django_site
cd django_site/
sudo djangocms -f -p . web_site

这一切都跟随着guide
执行上述最后一条命令后会抛出此错误：

The installation has failed.

你们中有人对此有解决方案吗？

（我的 Python 版本：2.7.13）

看起来是 Pillow 安装失败了。你需要先安装python开发库

# Python 2
sudo apt-get install python-dev python-setuptools

# Python 3
sudo apt-get install python3-dev python3-setuptools

您还必须安装一些其他先决条件。 Pillow 文档为 Ubuntu 14.04 提供了以下先决条件。我不确定 Raspian Stretch 的等价物是什么

sudo apt-get install libtiff5-dev libjpeg8-dev zlib1g-dev \
libfreetype6-dev liblcms2-dev libwebp-dev libharfbuzz-dev libfribidi-dev \
tcl8.6-dev tk8.6-dev python-tk

请参阅Pillow docs 了解更多信息。

既然您要开始一个新项目，请允许我鼓励您使用 Python 3！

我会尝试让 Pillow 自行安装，而不是运行 Django CMS 安装程序。如果失败，那么错误信息应该更明显。

pip install Pillow

如果最新版本失败，您可以尝试 3.0，因为这似乎是 Django CMS 的最低版本。

pip install 'Pillow==3.0'
