我有一个项目最近升级到了 Rails 5.2，并且我正在使用 webpacker gem。我在尝试部署到 Heroku 时收到以下错误：
\n\n...\nremote: Webpacker is installed \nremote: Using /tmp/build_b969a2366f45a65a0c09b6aaa4b24667/config/webpacker.yml file for setting up webpack paths\nremote: Compiling\xe2\x80\xa6\nremote: Compilation failed:\nremote: /tmp/build_b969a2366f45a65a0c09b6aaa4b24667/vendor/bundle/ruby/2.5.0/gems/webpacker-3.5.5/lib/webpacker/webpack_runner.rb:11:in `exec\': No such file or directory - /tmp/build_b969a2366f45a65a0c09b6aaa4b24667/node_modules/.bin/webpack (Errno::ENOENT)\nremote: from /tmp/build_b969a2366f45a65a0c09b6aaa4b24667/vendor/bundle/ruby/2.5.0/gems/webpacker-3.5.5/lib/webpacker/webpack_runner.rb:11:in `block in run\'\nremote: from /tmp/build_b969a2366f45a65a0c09b6aaa4b24667/vendor/bundle/ruby/2.5.0/gems/webpacker-3.5.5/lib/webpacker/webpack_runner.rb:10:in `chdir\'\nremote: from /tmp/build_b969a2366f45a65a0c09b6aaa4b24667/vendor/bundle/ruby/2.5.0/gems/webpacker-3.5.5/lib/webpacker/webpack_runner.rb:10:in `run\'\nremote: from /tmp/build_b969a2366f45a65a0c09b6aaa4b24667/vendor/bundle/ruby/2.5.0/gems/webpacker-3.5.5/lib/webpacker/runner.rb:6:in `run\'\nremote: from ./bin/webpack:15:in `<main>\'\n...\n在本地，我的 \'node_modules\' 目录位于 .gitignore 中（我相信 webpacker 安装脚本之一将其放在那里）。
