我正在使用Clojure的后端和使用React和Reagent的Clojurescript前端编写一个Web应用程序。我正在尝试将其托管在Heroku上。
当我在lein ubjerar本地运行时，它可以正常运行并且该应用程序可以运行。
但是，当我尝试通过将应用程序部署到Heroku时git push heroku master，总是会遇到如下错误：
remote: Preparing npm packages
remote: Installing npm packages
remote: npm packages successfully installed
remote: Running shadow-cljs...
remote: [:app] Compiling ...
remote: The required JS dependency "object-assign" is not available, it was required by "node_modules/react/cjs/react.production.min.js".

remote:
To https://git.heroku.com/getfluentspanish.git
! [remote rejected] master -> master (pre-receive hook declined)
出现这种情况，尽管这一事实object-assign被列为的依赖reactNPM包，我已经列为项:npm-deps在我的project.clj。我已经验证，当我在本地构建时，该软件包可以很好地安装（即在这种情况下node_modules/object-assign存在）。
当我在中手动添加object-assign为显式依赖项时:npm-deps，出现相同的错误，但抱怨应该自动安装（并在本地安装）的其他缺少的依赖项。当我添加新的缺少的依赖项时，它会抱怨另一个。当我在本地使用新的显式依赖进行构建时，可以工作，但抱怨现在存在版本冲突，因为隐式依赖通常固定在其他版本上。lein uberjar
知道我该如何解决吗？
编辑这是我的project.clj

编辑2我最终放弃了git push heroku master部署方法，转而使用Docker。我在下面的答案中详细介绍了该过程。
我最终放弃了基于Git的Heroku部署，而是对其进行了重新设计以改为使用Docker。现在，它的工作原理，但唯一的缺点是，我现在我要部署每一次，这是慢于在本地建设一个新码头工人的图像git push heroku master，然后lein uberjar在遥控器上。不过，我可以将此步骤移至CI服务器或其他设备上，并通过Github挂钩进行构建和部署，从而为我提供了类似的便利。
实际上，使用Docker的简单性给我留下了深刻的印象。在Dockerfile我使用的是非常简单的：
FROM openjdk:8-alpine
COPY target/uberjar/getfluentspanish.jar /getfluentspanish/app.jar
EXPOSE 3000
CMD ["java", "-jar", "/getfluentspanish/app.jar"]
我希望这对尝试将全栈Clojure＆Clojurescript应用程序部署到Heroku的人有所帮助。
