ruby-on-rails - 在 Rails 中加载 webpack javascript 时出现 EOFError

问题描述

我的 Rails 6 项目中有一个文件app/javascript/packs/application.js。当我加载站点的本地开发版本时，它会尝试通过 http://localhost:4000/packs/js/application-ed3ae63cdf581cdb86b0.js 检索它（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），但对 JS 文件的请求失败并返回 500：

Puma caught this error: end of file reached (EOFError)

此文件在本地不存在：

$ ls public/packs/js/application-ed3ae63cdf581cdb86b0.js
ls: public/packs/js/application-ed3ae63cdf581cdb86b0.js: No such file or directory

但是具有另一个指纹的版本确实（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。在此之后，我尝试过

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，清除浏览器缓存和不同的浏览器。

我正在使用bin/server而不是bin/webpacker-dev-server并且没有更改我的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？提前致谢！
