異常引發：未找到 {%extends "base.html"%}，導致 Heroku 中出現“500 Internal Server Error”

Question

我目前正在嘗試使用 heroku 啟動我的網站。 我觀看了一個 yt 教程並按照所有步驟創建了一個 requirements.txt 和 Procfile。 當我構建我的應用程序時出現問題，它成功部署了它，但在網站本身上它顯示了內部服務器錯誤。 我試圖通過 localhost 運行該應用程序，它運行良好。 我還查了谷歌，嘗試了許多來自不同網站的建議，但都沒有成功。

這是我的代碼：requirement.txt：

bcrypt==3.2.2
certifi==2022.6.15
cffi==1.15.1
charset-normalizer==2.1.0
click==8.1.3
colorama==0.4.5
dnspython==2.2.1
email-validator==1.2.1
Flask==2.2.2
Flask-Bcrypt==1.0.1
Flask-Login==0.6.2
Flask-SQLAlchemy==2.5.1
Flask-WTF==1.0.1
greenlet==1.1.2
gunicorn==20.1.0
idna==3.3
itsdangerous==2.1.2
Jinja2==3.1.2
MarkupSafe==2.1.1
pycparser==2.21
requests==2.28.1
SQLAlchemy==1.4.40
tailwind==3.1.5b0
tailwindcss==0.0.1
urllib3==1.26.11
Werkzeug==2.2.2
WTForms==3.0.1

Procfile（沒有.txt）：

web: gunicorn main:app

（與.txt沒有變化）

路由到 index.html：

@app.route("/home")
@app.route("/")
def index():
  return render_template("index.html")

索引.html：

{%extends "base.html"%}

我還嘗試了許多其他方法，例如將所有 _ 取出或使用 '' 而不是 ""。 它們都在本地主機中工作，但不在 heroku 中

此外 base.html 與所有其他模板位於同一文件夾中（文件夾稱為模板）

如果您能提供幫助，非常感謝！

Answer 1

所以我終於管理了一些東西，我做了什么，也許在其他一些人有的情況下，我將我的 base.html 移動到名為 base 的第二個文件夾。 然后我寫了同樣的擴展行：

{% extends "base/base.html"%}

最終對我有用的東西。 最后一部分可能與運行時錯誤有關，但已完成。
