我正在使用 Django-Compressor Filter 作为 Wagtail(具有超酷 UI 的 Django 变体 CMS)的一部分。环境是 Wagtail 0.2 + Python 2.7 + Django 1.6 + Virtualenv + FastCGI + Apache 共享主机。
尝试访问 CMS 的管理/登录页面时出现问题。 Django 显示错误渲染模板
Error during template rendering
In template /home/username/env/lib/python2.7/site-packages/wagtail/wagtailadmin/templates/wagtailadmin/skeleton.html, error at line 20
/bin/sh: django_libsass.SassCompiler: command not found
skeleton.html 的第 20 行是:

我的settings.py中的预编译器，DEBUG设置为True:
COMPRESS_ENABLED = True
COMPRESS_PRECOMPILERS = (
('text/x-scss', 'django_libsass.SassCompiler'),
)
尝试和错误#1
我试过改成:
('text/x-scss', '/home/username/env/lib/python2.7/site-packages/django_libsass {infile} {outfile}')
但这导致我出现字典更新序列元素 #0 错误。
我安装了 django_libsass 和压缩器，还尝试了 pip install libsass、ngm install lessc、pip install sass、打开 DEBUG = False，添加 COMPRESSOR_OFFLINE，按照其他类似问题中的建议添加 COMPRESSOR_ENABLED。运行 manage.py compress 返回相同的错误。
已重新检查，站点包和 django_libsass 确实在我的 sys.path 上
SassCompiler 可以在 ~/env/lib/python2.7/site-packages/django_libsass.py 中找到
尝试和错误#2
重新检查 sass 是否已安装并在我的路径上。
将代码更改为:
COMPRESS_PRECOMPILERS = (
('text/x-scss', 'sass --scss {infile} {outfile}'),
)
返回错误:
Exception Type: FilterError
Exception Value:
/bin/sh: sass: command not found
尝试和错误 #3
看完这篇feedly issue , 试过 pip install compass 没有效果
尝试和错误 #4
根据 gasman 的评论，我运行了 python manage.py shell 并尝试导入 SassCompiler 它没有错误。

最佳答案
(根据要求重新发布我的评论作为答案...)
原始错误:django_libsass.SassCompiler: command not found
意味着它无法导入 django-libsass 库。 (django-compressor 通过尝试将其视为 shell 命令来响应该失败 - django_libsass 不是可运行的命令，所以这也失败了，给出了此处看到的实际错误。)解决方案是确保安装了 django-libsass - 它应该出现在 pip freeze 的输出中。
第二个错误:'module' object has no attribute 'compile'
意味着安装了另一个包，它定义了一个名为 sass 的模块，它正在从 libsass 包中加载来代替我们想要的模块。解决方案是卸载除 django-libsass 和 libsass 之外的所有 sass 相关包。
