python manage.py 收集静态不起作用引发“utf-8”编解码器无法解码字节 0xff 问题

问题描述

大家好，我一直在尝试将我的 django 应用程序部署到 heroku，但我遇到了一些问题。

下面是我在 settings.py 文件中的一些静态设置

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR,'static')
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesstorage'
MEDIA_ROOT = os.path.join(BASE_DIR,'media')
MEDIA_URL = '/media/'  # this takes us to 'src/media/'    not 'static/media'

下面的 2 行产生相同的错误。

python manage.py collectstatic
heroku run python manage.py collectstatic

python manage.py collectstatic 的错误是

(venv) nmj@pc-nm:~/PROJECTS/abc/b99/mysite/src$ python manage.py collectstatic
You have requested to collect static files at the destination
location as specified in your settings:

    /home/nmj/PROJECTS/abc/blueMust/mysite/src/staticfiles

This will overwrite existing files!
Are you sure you want to do this?

Type 'yes' to continue,or 'no' to cancel: yes

下面是第 2 行 heroku run python manage.py collectstatic

产生的错误

我已经做了什么。 我跑了heroku config:set disABLE_COLLECTSTATIC=1 然后我打开了错误日志中的 storage.py 文件并尝试将 line 288 in error log 1 or line 282 in error log 2 both as shown above content = original_file.read().decode("utf-8") 更改为 content = original_file.read().decode("utf-16") 但得到了同样的错误。 然后我做了 content = original_file.read().decode() 和 content = original_file.read() 并得到了一系列错误。 我到处搜索，但可用的解决方案适用于当您尝试从 .csv 文件中读取时，例如在 Pandas 中说 我还没有找到解决我的具体问题的解决方案。

有人请帮助我，因为这个 heroku 东西从教程中看起来很简单，但由于我什至不知道的原因，它变得非常耗时。

任何帮助将不胜感激。

解决方法

在 settings.py 中添加静态文件目录路径。然后运行 ​​collectstatic 命令。

STATICFILES_DIRS = [
    os.path.join(BASE_DIR,"static"),]
