我有带有构建环境的烧瓶应用程序
./bin/pip show flask | grep Version
Version: 0.10.1
./bin/pip show flask-assets | grep Version
Version: 0.10
在src文件夹中 src/setup.py 有以下字符串
setup(
name = 'spf',
install_requires = [
'flask',
'flask-assets',
],
entry_points = {
'console_scripts': [
'spf_dev = spf.manage:dev', /* see manage.py dev function */
],
},
}
对于生成的 bin/spf_dev 我有 src/spf/manage.py 和以下代码
from flask.ext import assets
from . import env
def init (app):
manager = script.Manager(app)
manager.add_command(
'assets',
assets.ManageAssets(app.assets),
)
return manager
def dev ():
init(env.dev.app).run()
对于烧瓶环境初始化,我使用 src/spf/env/dev.py
from spf import init
app = init({
'ASSETS_DIR': 'src/spf/static/assets',
'ASSETS_URL': '/assets/',
'SASS_STYLE': 'compressed',
'UGLIFYJS_EXTRA_ARGS': (
'-c',
'--screw-ie8',
),
})
我在 src/spf/ init .py中实现了用于返回 wsgi 应用程序的 init 函数
import flask
from . import assets
def init (env_config=None):
app = flask.Flask(
'spf',
static_url_path='',
)
app.config.update(evn_config)
app.assets = assets.Assets(app)
return app
带有 Bundle 注册的 assets 模块 src/spf/assets.py
from flask.ext.assets import (
Environment,
Bundle,
)
class Assets (Environment):
def __init__ (self, app):
super(Assets, self).__init__(app)
if 'ASSETS_DIR' in app.config:
self.directory = app.config['ASSETS_DIR']
if 'ASSETS_URL' in app.config:
self.url = app.config['ASSETS_URL']
if 'SASS_STYLE' in app.config:
self.config['sass_style'] = app.config['SASS_STYLE']
if 'UGLIFYJS_EXTRA_ARGS' in app.config:
self.config['UGLIFYJS_EXTRA_ARGS'] = \
app.config['UGLIFYJS_EXTRA_ARGS']
self.register('theme.css', Bundle(
'scss/theme.scss',
filters='scss',
output='theme.css',
))
self.append_path('src/assets')
src/assets/scss/theme.scss
@import 'btn-o';
src/assets/scss/_btn-o.scss 存在,不为空且有0777访问权限
但是当我跑步时
buildout -c src/buildout.cfg
./bin/spf_dev assets -v build
我有错误
Building bundle: theme.css
Failed, error was: sass: subprocess had error: stderr=Error: File to import not found or unreadable: ./btn-o. on line 1 of standard input
Use --trace for backtrace. , stdout=, returncode=65
我已阅读https://github.com/miracle2k/webassets/blob/master/src/webassets/filter/sass.py#L36
但我不明白 ;-( 在我使用 self.append_path('src/assets') 之后,为什么 sass 不使用 src/assets 来解析来自 stdin 的 @import 指令中的相对路径?
