我刚刚第一次将我的应用程序推送到heroku但是当我访问页面时仍然遇到“应用程序错误”..我不熟悉heroku并且似乎无法在帮助/ dev中找到任何引用中心链接。
转到heroku日志我明白了：

我不确定这些意味着什么。但我认为它与gunicorn连接有关？有人可以帮助指出问题以及如何解决这个问题吗？
注意：没有ImportError：没有名为xxxxx的模块 - ＆gt; xxxxx是我的应用程序的名称..它也是我在procfile中使用的（例如xxxxx：app）。这是问题吗？
编辑：这是一个Flask应用程序，所以这里是我当前的结构
-static
--css
--img
--js
-templates
--index.html
--layout.html
-.gitignore
-Procfile
-requirements.txt
-app.py
我的Procfile：
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()
答案 0 :(得分：11)
将Procfile配置为：
web: gunicorn xxxxx:app
你正在给出Heroku将要运行的命令。在转向Heroku之前，应确保可以在开发计算机上运行此命令。
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，则该应用程序应为“app”（不应包含.py扩展名）。您得到的错误是因为gunicorn发出import xxxxxx并且显然因为您没有使用该名称定义包或模块而失败。
在冒号的另一侧，您必须输入应用程序的名称。例如，如果 app.py 文件中包含以下代码：
app = Flask(__name__)
然后您的应用程序名称为app。对于此设置，Procfile应为：
web: gunicorn app:app
然后，gunicorn会发出import app（左侧app），然后在那里寻找一个名为app的符号（右侧app）。
我希望这会有所帮助。
