问题描述

I currently trying to launch my website with heroku.我目前正在尝试使用 heroku 启动我的网站。 I watched a yt tutorial and followed all the steps, creating a requirement.txt and Procfile.我观看了一个 yt 教程并按照所有步骤创建了一个 requirements.txt 和 Procfile。 The problem occurs when I build my application it successfully deploys it but on the website itself it shows me Internal Server Error.当我构建我的应用程序时出现问题，它成功部署了它，但在网站本身上它显示了内部服务器错误。 I have tried to run the app through localhost and it works perfectly.我试图通过 localhost 运行该应用程序，它运行良好。 I also looked up on google and tried many suggestions from different sites without success.我还查了谷歌，尝试了许多来自不同网站的建议，但都没有成功。

Here is my code: requirement.txt:这是我的代码：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

Procfile (without.txt): Procfile（没有.txt）：

web: gunicorn main:app

(no change with.txt or not) （与.txt没有变化）

route to index.html:路由到 index.html：

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

index.html:索引.html：

{%extends "base.html"%}

I also tried many other ways, like taking all _ out or have '' instead of "".我还尝试了许多其他方法，例如将所有 _ 取出或使用 '' 而不是 ""。 They all work in localhost but not in heroku它们都在本地主机中工作，但不在 heroku 中

Also base.html is in the same folder as all other templates (folder is called templates)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）

Thank you so much if you can help!如果您能提供帮助，非常感谢！

So I finally managed something, what I did and maybe in some other cases that other people had, that I moved my base.html to a second folder called base.所以我终于管理了一些东西，我做了什么，也许在其他一些人有的情况下，我将我的 base.html 移动到名为 base 的第二个文件夹。 I then wrote the same extends line like that:然后我写了同样的扩展行：

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

what finally worked for me.最终对我有用的东西。 The last part stays probably with the runtime error but this is done.最后一部分可能与运行时错误有关，但已完成。
