在django中使用bootstrap4报错在aototest/settings.py 中加入如下内容:INSTALL_APPS = (#...'bootstrap4',#...在product_manage.html中:# {# Load the tag library #}{% load bootstrap4 %}# {# Load CSS and JavaScript #}{% bootstrap_css %}{% bootstrap_javascript jquery...

在django中使用bootstrap4报错

在aototest/settings.py 中加入如下内容:

INSTALL_APPS = (
	#...
	'bootstrap4',
	#...

在product_manage.html中:

# {# Load the tag library #}
{% load bootstrap4 %}

# {# Load CSS and JavaScript #}
{% bootstrap_css %}
{% bootstrap_javascript jquery='full' %}

随后访问 http://127.0.0.1:8000/product_manage/
链接失败。
查看development server已自动退出,重启server:

百度几天均无果,后重新安装bootstrap

pip install django-bootstrap4

runserver还是一样的报错。
重新运行:

python manage.py migrate

随后runserver成功:

总结为先

python manage.py migrate

python manage.py runserver

就成功了(不知道为啥,手动狗头)
截图为证:
在django中使用bootstrap4报错:OSError: [WinError 123] 文件名、目录名或卷标语法不正确。: ‘「frozen importlib._bootstrap」‘”
卡了我几天的坑,记录一下。

报错:TemplateSyntaxError at /apistep_manage/

Invalid block tag on line 48: ‘else’, expected ‘empty’ or ‘endfor’. Did you forget to register or load this tag?
在django中使用bootstrap4报错:OSError: [WinError 123] 文件名、目录名或卷标语法不正确。: ‘「frozen importlib._bootstrap」‘”
几经排查后还是找不到原因,后受文章 传送门 的启发,在if开始时的地方查找,找到问题所在:
在django中使用bootstrap4报错:OSError: [WinError 123] 文件名、目录名或卷标语法不正确。: ‘「frozen importlib._bootstrap」‘”
此处少了一个百分号%,添加上之后,报错解决。

报错:TemplateSyntaxError at /apistep_manage/

Could not parse the remainder: ‘% if apistep.apistatus == 1 %’ from ‘% if apistep.apistatus == 1 %’

在django中使用bootstrap4报错:OSError: [WinError 123] 文件名、目录名或卷标语法不正确。: ‘「frozen importlib._bootstrap」‘”
经排查,系此处多了一对花括号,去除一对花括号后,该报错解决。

报错:Unclosed tag on line 37: ‘for’. Looking for one of: empty, endfor.

在django中使用bootstrap4报错:OSError: [WinError 123] 文件名、目录名或卷标语法不正确。: ‘「frozen importlib._bootstrap」‘”
后排除问题如下:
在django中使用bootstrap4报错:OSError: [WinError 123] 文件名、目录名或卷标语法不正确。: ‘「frozen importlib._bootstrap」‘”
最后显示界面如下:
在django中使用bootstrap4报错:OSError: [WinError 123] 文件名、目录名或卷标语法不正确。: ‘「frozen importlib._bootstrap」‘”
总结:一定要注意百分号空格/百分号是否成对/一对百分号是否写成了两对。。。引以为戒中。。。

报错:TypeError: bug_manage() missing 1 required positional argument: ‘request’

在django中使用bootstrap4报错:OSError: [WinError 123] 文件名、目录名或卷标语法不正确。: ‘「frozen importlib._bootstrap」‘”
经排查,系此处括号有问题:
在django中使用bootstrap4报错:OSError: [WinError 123] 文件名、目录名或卷标语法不正确。: ‘「frozen importlib._bootstrap」‘”

runserver时报错:

raise RuntimeError(“cryptography is required for sha256_password or caching_sha2_password”)
RuntimeError: cryptography is required for sha256_password or caching_sha2_password
原因是没有连接数据库。
