我正在使用 Django-Compressor Filter 作为 Wagtail 的一部分（具有超酷 UI 的 Django 变体 CMS）。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 显示错误呈现模板

    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 = (

试错 #1

我尝试更改为：

('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。

我已经安装了 django_libsass 和压缩器，还尝试了, , pip install libsass, ngm install lesscturn pip install sass, added , added其他类似问题中的建议。运行返回相同的错误。DEBUG = FalseCOMPRESSOR_OFFLINECOMPRESSOR_ENABLEDmanage.py compress

已经重新检查并且站点包和 django_libsass 确实在我的 sys.path 上

SassCompiler 可以在~/env/lib/python2.7/site-packages/django_libsass.py

试错#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:

试错#3

阅读此feedly 问题后，尝试 pip install compass无效

试错#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。

如果这个问题太长，我深表歉意。

（根据要求重新发布我的评论作为答案......）

原来的错误：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 命令来响应该故障 - 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 django-libsass - 它应该出现在pip freeze.

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 的模块sass，并且正在从 libsass 包中加载它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。

我的 Python-Django 项目和 rvm 遇到了同样的问题。问题是压缩预编译器不知道要使用哪个 rvm。解决方案是将ruby路径添加到environ并告诉预编译器在settings.py文件中的哪里可以找到sass：

就像我的情况一样（只需which sass找到路径）：

 environ['PATH'] = '/Users/username/.rvm/gems/ruby-2.1.5/bin:/Users/username/.rvm/gems/ruby-2.1.5@global/bin:/Users/username/.rvm/rubies/ruby-2.1.5/bin:Users/username/bin'

 COMPRESS_PRECOMPILERS = (
 ('text/x-scss', '/Users/username/.rvm/gems/ruby-2.1.5/bin/sass --scss --trace {infile} {outfile}'),
 )

希望这可以帮助某人。

错误

/bin/sh: django_libsass.SassCompiler: command not found

表示 Django Compressor 正在尝试django_libsass.SassCompiler作为 shell 命令运行，并且脚本无法运行。

那是因为django_libsass.SassCompiler不是可以从命令行运行的有效程序。

如果您还没有安装 sass，最好的办法是先安装 sass，按照此页面上的说明进行操作：http: //sass-lang.com/install

然后将您的代码更改为：

 COMPRESS_PRECOMPILERS = ( 
     ('text/x-scss', 'sass --scss {infile} {outfile}'), 
 )

您必须确保该sass命令在您的路径上。

从文档（http://django-compressor.readthedocs.org/en/latest/settings/#django.conf.settings.COMPRESS_PRECOMPILERS）你的元组的第二部分是：

调用每个文件的命令。将为两个占位符 {infile} 和 {outfile} 提供现代 Python 字符串格式，它们在命令字符串中的存在也会触发这些临时文件的实际创建。如果在命令字符串中没有给出，Django Compressor 将分别使用 stdin 和 stdout。

pip install django_pyscss将解决您的问题。
