我正在尝试在14.04.1-Ubuntu上安装ReviewBoard，我收到以下错误。我使用过命令：
sudo apt-get install python-setuptools python-dev memcached patch libjpeg-dev
sudo pip install -U pip
sudo easy_install pip
sudo apt-get install python-mysqldb
sudo pip install ReviewBoard

有没有想法为什么会发生以及如何解决？
修改
sudo apt-get install -y libtiff5-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk
sudo pip install pillow
现在得到：

答案 0 :(得分：5)
您是否尝试过安装libffi-devel
apt-get install libffi-dev
有时需要修复点差问题，这对于安装build-essential和python-dev
apt-get install python-dev && apt-get install build-essential
答案 1 :(得分：1)
sudo apt-get install -y libtiff5-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk
sudo pip install pillow
然后ccfi使用（Failed to install Python Cryptography package with PIP and setup.py）：
sudo apt-get install libffi-dev libssl-dev libpython2.7-dev
sudo pip install cryptography
sudo pip install cffi
答案 2 :(得分：0)
要在CentOS 7上运行Python 2.7 Fabric 1.13，我必须首先安装openssl-devel。
完成错误：
#include <openssl/opensslv.h>
^
compilation terminated.
error: command 'gcc' failed with exit status 1
----------------------------------------
Command "/usr/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-2hTQUe/cryptography/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-mqFBbh-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-2hTQUe/cryptography/
解决方案：
sudo yum install -y gcc make openssl openssl-devel
sudo pip install fabric
