无法将 RoR 应用程序部署到 Heroku - SQLite3 已从 Gem.file 和 Gemfile.lock 中删除

Can't deploy RoR app to Heroku - SQLite3 already removed from Gem.file and Gemfile.lock

我正在尝试将我的应用程序部署到 Heroku,但每次推送 master 分支时都会收到以下错误。

SQLite3 已从我的 gem 和 gem 锁定文件中删除,它已全部推送到 git 并与 master 分支合并。我的 database.yml 已更新为使用 postgresql 而不是 sqlite3。任何想法是什么导致失败?

此处列出了参考文件:

我发现了问题 - 即使我将我的更改推送到 Git,我也没有将 master 拉回我的电脑。当我 运行 git push heroku master 发送的文件仍然包含 sqlite3 gem 即使它在我的文件和 Git 枢纽大师。一旦我 运行 git checkout mastergit pull origin master,我就能够部署到 Heroku。
