Webpacker successfully installed �🎉🍰🍰
Webpacker::Manifest::MissingEntryError in Welcome#index
Showing C:/Users/[...]/site_test/app/views/layouts/application.html.erb where line #9 raised:
Webpacker can't find application in C:/Users/[...]/site_test/public/packs/manifest.json. Possible causes:
1. You want to set webpacker.yml value of compile to true for your environment
unless you are using the `webpack -w` or the webpack-dev-server.
2. webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your webpack configuration is not creating a manifest.
Your manifest contains:
{
}
Extracted source (around line #9):

推荐答案
感谢您的帮助。不幸的是,什么都不起作用。
rails assets:clobber
删除NODE_MODULES文件夹后立即返回";错误:找不到完整性文件&/strong>。(纱线安装后工作--检查文件)。
ANDrails assets:precompile
返回
"C:/Ruby26-x64/lib/ruby/gems/2.6.0/gems/webpacker-4.0.7/lib/webpacker/webpack_runner.rb:23:in `exec': No such file or directory - C:Users[...]site_test
ode_modules.bin/webpack (Errno::ENOENT)"
但我发现了问题所在:我电脑中的位置! 可能是名称问题...
