Python3.7&Django1.11.15 兼容性問題

環境：

1. Windows10

2. python3.7

3. Django1.11.15

 

啓動Django時拋出如下異常：

Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x0000024D934BDD08> Traceback (most recent call last): File "C:\Python37\lib\site-packages\django\utils\autoreload.py", line 228, in wrapper fn(*args, **kwargs) File "C:\Python37\lib\site-packages\django\core\management\commands\runserver.py", line 116, in inner_run autoreload.raise_last_exception() File "C:\Python37\lib\site-packages\django\utils\autoreload.py", line 251, in raise_last_exception six.reraise(*_exception) File "C:\Python37\lib\site-packages\django\utils\six.py", line 685, in reraise raise value.with_traceback(tb) File "C:\Python37\lib\site-packages\django\utils\autoreload.py", line 228, in wrapper fn(*args, **kwargs) File "C:\Python37\lib\site-packages\django\__init__.py", line 27, in setup apps.populate(settings.INSTALLED_APPS) File "C:\Python37\lib\site-packages\django\apps\registry.py", line 85, in populate app_config = AppConfig.create(entry) File "C:\Python37\lib\site-packages\django\apps\config.py", line 94, in create module = import_module(entry) File "C:\Python37\lib\importlib\__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1006, in _gcd_import File "<frozen importlib._bootstrap>", line 983, in _find_and_load File "<frozen importlib._bootstrap>", line 967, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 677, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 728, in exec_module File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed File "C:\Python37\lib\site-packages\django\contrib\admin\__init__.py", line 4, in <module> from django.contrib.admin.filters import ( File "C:\Python37\lib\site-packages\django\contrib\admin\filters.py", line 10, in <module> from django.contrib.admin.options import IncorrectLookupParameters File "C:\Python37\lib\site-packages\django\contrib\admin\options.py", line 13, in <module> from django.contrib.admin import helpers, widgets File "C:\Python37\lib\site-packages\django\contrib\admin\widgets.py", line 152 '%s=%s' % (k, v) for k, v in params.items(), ^ SyntaxError: Generator expression must be parenthesized

解決方法：

把「'%s=%s' % (k, v) for k, v in params.items(),」中的後邊的逗號去掉就ok了

 

 

linux下的解決：

Linux下啓動失敗跑拋出異常，和Windows下同樣，查看拋出異常的最後一個提示的路徑和行號。使用sudo編進該路徑下的該py文件，方法同上，保存就ok了

相似的文件路徑：

sudo vi /usr/local/lib/python3.7/site-packages/django/contrib/admin/widgets.p

related_url += '?' + '&'.join(
        '%s=%s' % (k, v) for k, v in params.items(),
    )
修改:
    related_url += '?' + '&'.join(
        '%s=%s' % (k, v) for k, v in params.items()
    )
