我目前正在尝试推出我的网站与heroku。我看了一个yt教程，并按照所有的步骤，创建requirement.txt和Procfile。问题发生在我构建我的应用程序时，它成功地部署了它，但在网站本身上，它显示我内部服务器错误。我曾尝试通过localhost运行应用程序，它工作得很完美。我也在谷歌上查了一下，尝试了很多不同网站的建议，都没有成功。
下面是我的代码：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

过程文件（不带.txt）：

web: gunicorn main:app

(no是否使用.txt更改）
路由到index.html：

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

index.html:

{%extends "base.html"%}

我也尝试了很多其他的方法，比如把all _ out去掉，或者用"“代替“"。它们都可以在localhost中工作，但在heroku中不行
此外，base.html与所有其他模板位于同一文件夹中（文件夹称为模板）
如果你能帮忙的话，非常感谢！

所以我最终做了一些事情，我做了什么，也许在其他一些情况下，其他人也做了什么，我把我的base.html移到了第二个文件夹base中，然后我写了同样的extends行，如下所示：

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

最后一部分可能与运行时错误有关，但这已经完成。
