我有一个文件app/javascript/packs/application.js在我的Rails 6项目。当我加载站点的本地开发版本时，它试图通过http://localhost:4000/packs/js/application-ed3ae63cdf581cdb86b0.js检索(我在自定义端口上运行以避免与另一个应用程序发生冲突)，但是对JS文件的请求失败了500:
Puma caught this error: end of file reached (EOFError)

这个文件在本地不存在:
$ ls public/packs/js/application-ed3ae63cdf581cdb86b0.js
ls: public/packs/js/application-ed3ae63cdf581cdb86b0.js: No such file or directory
，但另一个指纹的版本可以(并且非空):
$ ls -alh public/packs/js/application-*
-rw-r--r-- 1 sam staff 188K 24 Feb 17:58 public/packs/js/application-fdef50bf044896f1dc71.js
-rw-r--r-- 1 sam staff 212K 24 Feb 17:58 public/packs/js/application-fdef50bf044896f1dc71.js.map
我无法让我的网站请求正确的文件。接下来，我尝试了
rake assets:clean
rake assets:precompile
touch tmp/restart.txt
，但无济于事。我还尝试了一个私人浏览器窗口，清除浏览器缓存和一个不同的浏览器。
我使用bin/server而不是bin/webpacker-dev-server，并没有改变我的webpacker.yml(它是在init上自动创建的，然后在我安装React时自动更新)，但如果它有帮助，它看起来像这样:

我错过了什么?提前感谢!
看到你没有使用开发服务器，你的资产很可能在public/packs中有一个旧版本，这让我想到了几件事。
尝试删除包文件夹并运行bin/server
我在另一个场合遇到了这个问题的变体(同样的错误，但正确名称的文件在public/packs/js中)，并设法通过不再在自定义端口上运行我的Rails应用程序来解决它。
此外，当我停止该服务器并重新运行它时，重新应用自定义端口，然后在该上下文中正确加载资源。
