LookupError：在蛋'YYY'中找不到入口点'XXX'，但在蛋'YYY'中存在XXX

Question

我目前正在快速查看，但我被困在运行代理上。以下是我在运行“swift-init proxy restart”时遇到的错误。

Traceback (most recent call last):

LookupError: Entry point 'tempurl' not found in egg 'swift' (dir: /usr/local/lib/python2.7/dist-packages; protocols: paste.app_factory, paste.composite_factory, paste.composit_factory; entry_points: )

所以我查看了 dist-packages 中存在的 egg-info 和源文件。

/usr/local/lib/python2.7/dist-packages/swift-1.12.0.113.g076634e.egg-info/entry_points.txt

[paste.filter_factory]
formpost = swift.common.middleware.formpost:filter_factory
gatekeeper = swift.common.middleware.gatekeeper:filter_factory
container_quotas = swift.common.middleware.container_quotas:filter_factory
container_sync = swift.common.middleware.container_sync:filter_factory
catch_errors = swift.common.middleware.catch_errors:filter_factory
ratelimit = swift.common.middleware.ratelimit:filter_factory
keystoneauth = swift.common.middleware.keystoneauth:filter_factory
tempauth = swift.common.middleware.tempauth:filter_factory
list_endpoints = swift.common.middleware.list_endpoints:filter_factory
dlo = swift.common.middleware.dlo:filter_factory
name_check = swift.common.middleware.name_check:filter_factory
domain_remap = swift.common.middleware.domain_remap:filter_factory
proxy_logging = swift.common.middleware.proxy_logging:filter_factory
crossdomain = swift.common.middleware.crossdomain:filter_factory
healthcheck = swift.common.middleware.healthcheck:filter_factory
tempurl = swift.common.middleware.tempurl:filter_factory
bulk = swift.common.middleware.bulk:filter_factory
memcache = swift.common.middleware.memcache:filter_factory
account_quotas = swift.common.middleware.account_quotas:filter_factory
staticweb = swift.common.middleware.staticweb:filter_factory
cname_lookup = swift.common.middleware.cname_lookup:filter_factory
recon = swift.common.middleware.recon:filter_factory
slo = swift.common.middleware.slo:filter_factory

正如你在上面看到的，'tempurl = swift.common.middleware.tempurl:filter_factory'行实际上存在（我不熟悉鸡蛋结构，所以我不确定这些行是否足以运行。）确认这些行后，我发现 tempurl.py 实际上存在于 /usr/local/lib/python2.7/dist-packages/swift/common/middleware/tempurl.py 中。看起来一切都足以加载 tempurl.py。我应该去哪里解决这个问题。 提前感谢您的帮助。

ps。 我阅读的每个文档都使用 '[filter:tempurl]' 作为 proxy-server.conf。但是我在下面遇到了错误，所以我将其更改为“[app:tempurl]”。我面临第二个问题。第一个问题也来自“loadwsgi”。所以我假设第一个问题也与这个加载鸡蛋问题有关。

LookupError: No section 'tempurl' (prefixed by 'app' or 'application' or 'composite' or 'composit' or 'pipeline' or 'filter-app') found in config /etc/swift/proxy-server.conf

Answer 1

我删除了以下几行：

#[filter:authtoken]
#use = egg:swift#proxy
#allow_account_management = true
#account_autocreate = true

这是修复之前的错误输出。为了科学！！！
