Question

我部署了an API，它在本地运行良好。 但是，即使它被标记为“已部署”，当我尝试执行这样的请求时，仍会出现以下错误：

https://perfumerecommender-api.herokuapp.com/perfume?features=elegant

我得到：

是因为要求吗

Flask==1.1.2
Flask-Cors==3.0.8
Flask-RESTful==0.3.7
gunicorn==20.0.4
joblib==0.13.2
jsonschema==2.6.0
pandas
pickleshare==0.7.5
requests==2.23.0
requests-file==1.4.3
wcwidth==0.1.7
webencodings==0.5.1
Werkzeug==1.0.1

我删除并添加了Procfile，现在出现错误14：

2021-07-03T13:11:36.799997+00:00 heroku[router]: at=error code=H14 desc="No web processes running" method=GET path="/favicon.ico" host=perfumerecommender-a

这是我的Procfile：

web: gunicorn app:app --max-requests 2

我试图确定正在执行的Dyno的数量，但它似乎崩溃了：

(venv) C:\Users\antoi\Documents\Programming\Learning\API>heroku ps
Free dyno hours quota remaining this month: 993h 14m (99%)
Free dyno usage for this app: 0h 4m (0%)
For more information on dyno sleeping and how to upgrade, see:

=== web (Free): gunicorn (1)
web.1: crashed 2021/07/03 16:11:21 +0200 (~ 1m ago)

Answer 1

在heroku中，如果不声明Procfile，则无法运行任何项目。 {}告诉heroku如何运行您的项目
