我只是第一次将我的应用程序推送到 heroku,但是当我访问该页面时不断收到“应用程序错误”。我不熟悉 heroku,似乎无法在帮助/开发中找到任何引用中心链接。
转到 heroku 日志我得到这个:

我不太确定这些都是什么意思。但我假设它与 gunicorn 连接有关?有人可以帮助指出问题以及我该如何解决这个问题吗?
注意:no ImportError: No module named xxxxx --> xxxxx 是我的应用程序的名称。这也是我在 procfile 中使用的名称(例如 xxxxx:app)。这是问题所在吗?
编辑:这是一个 Flask 应用程序,所以这是我当前的结构
-static
--css
--img
--js
-templates
--index.html
--layout.html
-.gitignore
-Procfile
-requirements.txt
-app.py
我的文件:
web: gunicorn app:app
Edit2:这是我的 app.py 文件
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def main():
return render_template("index.html")
@app.route('/projects')
def projects():
...
...
if __name__ == '__main__':
app.run()
最佳答案
当你配置你的 Procfile 时:
web: gunicorn xxxxx:app
您正在发出 Heroku 将运行的命令。在您转向 Heroku 之前,您应该确保您可以在您的开发机器上运行这个命令。
您传递给 gunicorn 的“xxxxx”参数是 gunicorn 将导入以获取您的应用程序对象的包或模块。如果您在 app.py 中创建应用程序,那么它应该是“app”(不应包含 .py 扩展名)。出现错误是因为 gunicorn 发出了 import xxxxxx
并且显然失败了,因为您没有定义具有该名称的包或模块。
在冒号的另一边,您必须输入您的应用程序名称。例如,如果您的 app.py 文件中有以下代码:
app = Flask(__name__)
那么你的应用名称就是app
。对于此设置,Procfile 应为:
web: gunicorn app:app
然后gunicorn会发出一个import app
(左边的app
)然后在里面寻找一个名为app
的symbol(右边的)端 app
).
希望对您有所帮助。
