However, if multiple\n        specs are provided in a single call to ``add_translation_dirs``, the\n        directories will be inserted into the beginning of the directory list\n        in the order they're provided in the ``*specs`` list argument (items\n        earlier in the list trump ones later in the list).\n        \"\"\"\n        directories = []\n        introspectables = []\n    \n        for spec in specs[::-1]: # reversed\n            package_name, filename = self._split_spec(spec)\n            if package_name is None: # absolute filename\n                directory = filename\n            else:\n                __import__(package_name)\n                package = sys.modules[package_name]\n                directory = os.path.join(package_path(package), filename)\n    \n            if not os.path.isdir(os.path.realpath(directory)):\n>               raise ConfigurationError('\"%s\" is not a directory' %\n                                         directory)\nE               pyramid.exceptions.ConfigurationError: \"/home/gcpuser/buckets/local_repoeval_bucket/repos/pyramid_6c38039e37cf134615e773968644686fdc5012a6/r2e_tests/pkgs/localeapp/locale\" is not a directory\n\npyramid/config/i18n.py:91: ConfigurationError\n________ TestI18NConfiguratorMixin.test_add_translation_dirs_asset_spec ________\n\nself = <r2e_tests.test_config.test_i18n.TestI18NConfiguratorMixin testMethod=test_add_translation_dirs_asset_spec>\n\n    def test_add_translation_dirs_asset_spec(self):\n        from pyramid.interfaces import ITranslationDirectories\n        config = self._makeOne(autocommit=True)\n        config.add_translation_dirs('pyramid.tests.pkgs.localeapp:locale')\n>       self.assertEqual(config.registry.getUtility(ITranslationDirectories),\n                         [locale])\nE       AssertionError: Lists differ: ['/ho[70 chars]615e773968644686fdc5012a6/pyramid/tests/pkgs/localeapp/locale'] != ['/ho[70 chars]615e773968644686fdc5012a6/r2e_tests/pkgs/localeapp/locale']\nE       \nE       First differing element 0:\nE       '/hom[68 chars]4615e773968644686fdc5012a6/pyramid/tests/pkgs/localeapp/locale'\nE       '/hom[68 chars]4615e773968644686fdc5012a6/r2e_tests/pkgs/localeapp/locale'\nE       \nE       - ['/home/gcpuser/buckets/local_repoeval_bucket/repos/pyramid_6c38039e37cf134615e773968644686fdc5012a6/pyramid/tests/pkgs/localeapp/locale']\nE       ?

We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
[ISSUE]
**Title:** Router Fails to Fallback to Alternative Views on PredicateMismatch

**Description:**
When a view raises a `PredicateMismatch` exception, the router is expected to search for other views that satisfy the request predicates. However, currently, it incorrectly hides alternative views, resulting in the request failing even when a suitable fallback view exists.

**Example Code:**
```python
from pyramid.interfaces import IViewClassifier, IRequest
from pyramid.response import Response
from pyramid.router import Router
from pyramid.exceptions import PredicateMismatch

class BaseContext:
    pass

class DummyContext(BaseContext):
    pass

class FallingView:
    def __call__(self, context, request):
        raise PredicateMismatch("Predicate mismatch")

class GoodView:
    def __call__(self, context, request):
        return Response("abc")

# Setup router and register views
router = Router()
router.register_view(FallingView(), '', IViewClassifier, IRequest, DummyContext)
router.register_view(GoodView(), '', IViewClassifier, IRequest, BaseContext)

# Simulate a request
environ = {}  # Simplified request environment
start_response = DummyStartResponse()
app_iter = router(environ, start_response)

# Expected behavior: app_iter should contain [b'abc']
```

**Expected Behavior:**
When `FallingView` raises a `PredicateMismatch`, the router should attempt to find and invoke `GoodView`, resulting in the response `[b'abc']`.

**Actual Behavior:**
Instead of fallback to `GoodView`, the router stops the search and the request fails with a `PredicateMismatch` error, preventing the expected response from being returned.

Please first localize the bug based on the issue statement, and then generate *SEARCH/REPLACE* edits to fix the issue.

Every *SEARCH/REPLACE* edit must use this format:
1. The file path
2. The start of search block: <<<<<<< SEARCH
3. A contiguous chunk of lines to search for in the existing source code
4. The dividing line: =======
5. The lines to replace into the source code
6. The end of the replace block: >>>>>>> REPLACE

Here is an example:

```python
### mathweb/flask/app.py
<<<<<<< SEARCH
from flask import Flask
=======
import math
from flask import Flask
>>>>>>> REPLACE
```
</solution>

Please note that the *SEARCH/REPLACE* edit REQUIRES PROPER INDENTATION. If you would like to add the line '        print(x)', you must fully write that out, with all those spaces before the code!
Wrap each *SEARCH/REPLACE* edit in a code block as shown in the example above. If you have multiple *SEARCH/REPLACE* edits, use a separate code block for each one.
[ISSUE]
**Title:** Router Fails to Fallback to Alternative Views on PredicateMismatch

**Description:**
When a view raises a `PredicateMismatch` exception, the router is expected to search for other views that satisfy the request predicates. However, currently, it incorrectly hides alternative views, resulting in the request failing even when a suitable fallback view exists.

**Example Code:**
```python
from pyramid.interfaces import IViewClassifier, IRequest
from pyramid.response import Response
from pyramid.router import Router
from pyramid.exceptions import PredicateMismatch

class BaseContext:
    pass

class DummyContext(BaseContext):
    pass

class FallingView:
    def __call__(self, context, request):
        raise PredicateMismatch("Predicate mismatch")

class GoodView:
    def __call__(self, context, request):
        return Response("abc")

# Setup router and register views
router = Router()
router.register_view(FallingView(), '', IViewClassifier, IRequest, DummyContext)
router.register_view(GoodView(), '', IViewClassifier, IRequest, BaseContext)

# Simulate a request
environ = {}  # Simplified request environment
start_response = DummyStartResponse()
app_iter = router(environ, start_response)

# Expected behavior: app_iter should contain [b'abc']
```

**Expected Behavior:**
When `FallingView` raises a `PredicateMismatch`, the router should attempt to find and invoke `GoodView`, resulting in the response `[b'abc']`.

**Actual Behavior:**
Instead of fallback to `GoodView`, the router stops the search and the request fails with a `PredicateMismatch` error, preventing the expected response from being returned.

--- BEGIN ISSUE ---
[ISSUE]
**Title:** Router Fails to Fallback to Alternative Views on PredicateMismatch

**Description:**
When a view raises a `PredicateMismatch` exception, the router is expected to search for other views that satisfy the request predicates. However, currently, it incorrectly hides alternative views, resulting in the request failing even when a suitable fallback view exists.

**Example Code:**
```python
from pyramid.interfaces import IViewClassifier, IRequest
from pyramid.response import Response
from pyramid.router import Router
from pyramid.exceptions import PredicateMismatch

class BaseContext:
    pass

class DummyContext(BaseContext):
    pass

class FallingView:
    def __call__(self, context, request):
        raise PredicateMismatch("Predicate mismatch")

class GoodView:
    def __call__(self, context, request):
        return Response("abc")

# Setup router and register views
router = Router()
router.register_view(FallingView(), '', IViewClassifier, IRequest, DummyContext)
router.register_view(GoodView(), '', IViewClassifier, IRequest, BaseContext)

# Simulate a request
environ = {}  # Simplified request environment
start_response = DummyStartResponse()
app_iter = router(environ, start_response)

# Expected behavior: app_iter should contain [b'abc']
```

**Expected Behavior:**
When `FallingView` raises a `PredicateMismatch`, the router should attempt to find and invoke `GoodView`, resulting in the response `[b'abc']`.

**Actual Behavior:**
Instead of fallback to `GoodView`, the router stops the search and the request fails with a `PredicateMismatch` error, preventing the expected response from being returned.

          beginning of request processing.

        - causes a :class:`~pyramid.event.ContextFound` event to be sent
          when a context resource is found.
          
        - causes a :class:`~pyramid.event.NewResponse` event to be sent when
          the Pyramid application returns a response.

        - Calls any :term:`response callback` functions defined within the
          request's lifetime if a response is obtained from the Pyramid

Please first localize the bug based on the issue statement, and then generate *SEARCH/REPLACE* edits to fix the issue.

Every *SEARCH/REPLACE* edit must use this format:
1. The file path
2. The start of search block: <<<<<<< SEARCH
3. A contiguous chunk of lines to search for in the existing source code
4. The dividing line: =======
5. The lines to replace into the source code
6. The end of the replace block: >>>>>>> REPLACE

Here is an example:

```python
### mathweb/flask/app.py
<<<<<<< SEARCH
from flask import Flask
=======
import math
from flask import Flask
>>>>>>> REPLACE
```
</solution>

Please note that the *SEARCH/REPLACE* edit REQUIRES PROPER INDENTATION. If you would like to add the line '        print(x)', you must fully write that out, with all those spaces before the code!
Wrap each *SEARCH/REPLACE* edit in a code block as shown in the example above. If you have multiple *SEARCH/REPLACE* edits, use a separate code block for each one.
