如何在 Heroku 上部署 Python 模块?

pythonserver side programmingprogramming

假设您已在本地安装了 Python 3.6、Pipenv 和 heroku CLI,并使用此处提到的步骤从 CLI 登录 Heroku:https://devcenter.heroku.com/articles/getting-started-with-python#set-up。

您的应用程序需要有一个 git 存储库才能部署到 heroku。您需要 cd 到您的 git repo 代码根目录所在的目录中。现在您需要使用以下命令创建一个 heroku 应用程序:

$ heroku create
Creating lit-bastion-5032 in organization heroku... done, stack is cedar-14

http://lit-bastion-5032.herokuapp.com/ | https://git.heroku.com/lit-bastion-5032.git

已添加 Git 远程 heroku

创建应用程序时,还会创建一个 git 远程(称为 heroku),并将其与您的本地 git 存储库关联。 Heroku 会为您的应用生成一个随机名称(本例中为 lit-bastion-5032),或者您可以传递一个参数来指定您自己的应用名称。

现在已经添加了远程,您可以使用以下命令将您的代码推送到 heroku:

$ git push heroku master

Note that you need to specify your requirements(third party modules you are importing) with their version numbers(or without if you need latest one) in the requirements.txt. For example,
Flask==0.8
Jinja2==2.6
Werkzeug==0.8.3
certifi==0.0.8
chardet==1.0.1
