我在做什么 ？

• 我正在嘗試在 heroku 服務器上部署一個 django web 應用程式。

問題

• 我無法使用 .css 在 heroku 服務器中推送 css 檔案git push heroku main。

• 當我從靜態檔案夾中洗掉 css 檔案時，一切都很順利。

更多的

• 我也安裝了whitenoise.....

Heroku 不接受靜態檔案，您需要安裝 Whitenoise 并將其放入設定中。

看到這個檔案，它會作業！

白噪聲檔案

Heroku Whitenoise 檔案

PS：安裝 whitenoise 后，使用pip freeze > requirements.txt并更新您的要求

uj5u.com熱心網友回復：

python manage.py collectstatic

會作業

問題似乎是whitenoise.storage.MissingFileError。Whitenoise 正在尋找CSS/images/mobile-app.png在您的 css 檔案中參考的檔案CSS/style.css。因為它找不到那個檔案，所以它以ValueError.

解決方案是：

1. 更新您的 css 檔案 ( CSS/style.css) 中要查找的位置CSS/images/mobile-app.png。檢查參考它的 url 路徑是否正確。例如，它可能真的需要/images/mobile-app.png代替CSS/images/mobile-app.png.

2. 或者將丟失的檔案添加到預期的位置 ( CSS/images/mobile-app.png)。
