python - Pipfile.lock 已过期

Question

我正在尝试将一个大型 django 项目部署到 heroku。我安装了 Heroku CLI，登录，创建了一个应用程序并运行:

git push heroku master

我已经设置了 Pipfile 和 requirements.txt。我添加了一个 runtime.txt 来指定我需要 python 2.7。这也在 Pipfile 中。这是我从推送到 heroku 得到的:

$ git push heroku master

remote: 
To https://git.heroku.com/camp-infinity.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/camp-infinity.git'

出于某种原因，它尝试安装 python 3，而且它也不喜欢我的 Pipfile.lock 文件。我尝试删除它并使用 pipenv install 再次生成它，但这并没有改变任何东西。

做项目的时候遇到同样的问题，在你push到Heroku的分支，运行

pipenv lock

它会更新 Pipfile.lock 文件。 :)
