[英]TypeError from pkg_resources when using static assets in Pyramid
Trying to set up static assets on a Pyramid app.尝试在 Pyramid 应用程序上设置 static 资产。 I used the following call:
我使用了以下调用:
config.add_static_view(name='static', path='toolsofknowledge:static')
The file main.css
is stored under toolsofknowledge/static/main.css
, as expected.正如预期的那样,文件
main.css
存储在toolsofknowledge/static/main.css
下。 The toolsofknowledge
package is installed locally with an editable link, using pip3 install -e.
toolsofknowledge
使用pip3 install -e.
. .
Requesting http://localhost:8080/static/main.css
with curl causes this exception on the server:使用 curl 请求
http://localhost:8080/static/main.css
8CBA22E28EB17B5F5C6AE2A266AZ 会在服务器上导致此异常:

Solution: add __init__.py
to toolsofknowledge
directory.解决方法:将
__init__.py
添加到toolsofknowledge
目录。
The problem is quite simple -- the toolsofknowledge
package was not a real package, despite being installed, as it was missing an __init__.py
.问题很简单
toolsofknowledge
package 不是真正的 package,尽管已安装,因为它缺少__init__.py
。 This causes toolsofknowledge.__loader__
to be an instance of NamespaceLoader
, when it should be SourceFileLoader
.这会导致
toolsofknowledge.__loader__
成为NamespaceLoader
的一个实例,而它应该是SourceFileLoader
。 Obviously, pkg_resources
cannot resolve resources relative to something that's not a real package.显然,
pkg_resources
无法解析与不是真正的 package 的东西相关的资源。 Arguably it should handle this case more smoothly though.可以说它应该更顺利地处理这种情况。
