非常新的Node和部署到Heroku。我已经设置了一个基本的React应用程序,并且正在尝试部署到Heroku。我已经推送了,但应用程序失败了。当我查看日志时,我看到了一些关于sh: 1: webpack: not found
(full log here)的东西
我真的不确定发生了什么,但我相信这与我的package.json有关?在我使用的起始模板中,如下所示:

为了部署它,我做错了什么?在我的本地主机上运行得很好。却想不出怎样才能把它带到这个世界上。非常感谢!

好的--这与package.json中的devDependencies和Dependencies有关,通过将Heroku配置设置为NPM_CONFIG_PRODUCTION: false
,我能够解决这个问题。Thx互联网!

正如其他人所说,Heroku将node作为生产NODE_ENV=production
运行,这意味着您的devDependencies不会被安装。不过,Heroku提供了特定于节点的构建挂钩。我使用heroku-prebuild
运行npm install --dev
,它会安装所有依赖项和devDependencies。
"scripts": {
...,
"heroku-prebuild": "npm install --dev",
...
},
应该避免在非生产模式下运行你的应用程序。通常,开发人员有“开发模式”的特定代码,当在生产环境中运行时,这些代码会被过滤掉。此外,如果你正在做的事情是一个webpack构建,你肯定想要在生产模式,以利用缩小,丑化,等等。
以下是Heroku的详细信息。
有时,开发人员需要更多面向生产的东西,而不是package.json中的预安装和安装后挂钩。例如,一些应用程序需要在安装依赖项之前设置额外的身份验证。有些需要构建资产,但不是在开发环境中。在GitHub的讨论中可以找到更多的例子。
Node.js开发人员现在可以使用heroku-prebuild和heroku-postbuild挂钩来定制他们的应用程序的构建过程。

这是因为heroku默认没有安装package.json的dev依赖项,我们需要谨慎地告诉heroku (npm)安装我们的dev依赖项(webpack在dev中),所以运行这个命令应该可以解决“找不到”的问题。
。
npm install --dev
