生产服务器上的IOError

Question

我正在Django中编写一个使用以下第三方库的Web应用程序:

Django==1.6.1
argparse==1.2.1
cffi==0.8.1
pycparser==2.10
pylast==0.5.11
pyspotify==2.0.0a1
wsgiref==0.1.2

我一直在安装pyspotify,sudo pip install git+git://github.com/mopidy/pyspotify.git因为我想要开发版.

当我在本地运行Django应用程序时,一切都按预期工作.当我将更改提取到我的Apache服务器上时pip install -r requirements.txt,重新启动服务器并访问IP我收到以下错误:

Exception Value: [Errno 2] No such file or directory: '/usr/local/lib/python2.7/dist-packages/spotify/__pycache__/_cffi__x3868ddbbx77caf6c5.c'

当我pip freeze在服务器上看到所有依赖项都满足时,我不确定是什么问题.有没有人有想法？

Answer 1

假设您在尝试安装时遇到相同的编译器错误:

c/_cffi_backend.c:14:17: fatal error: ffi.h: No such file or directory

 #include <ffi.h>

                 ^

compilation terminated.

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

我发现修复在这里 做apt-get install libffi-dev
