Question

使用： ruby "2.4.0" gem "rails", "5.1.0.rc1" gem "pg", "0.18.4" # postgresql database gem foreman gem "webpacker", git: "https://github.com/rails/webpacker" 我跑的时候，

bundle exec foreman start -f Procfile.dev 其中包含以下3行：

rails: bin/rails s -b 0.0.0.0
webpack-dev-server: bin/webpack-dev-server
memcached: memcached

这是rails s的内容

#!/usr/bin/env ruby
APP_PATH = File.expand_path('../config/application', __dir__)
require_relative '../config/boot'
require 'rails/commands

这是webpack-dev-server的内容：

#!/usr/bin/env ruby
$stdout.sync = true

require "shellwords"
require "yaml"

ENV["RAILS_ENV"] ||= "development"
RAILS_ENV = ENV["RAILS_ENV"]

ENV["NODE_ENV"] ||= RAILS_ENV
NODE_ENV = ENV["NODE_ENV"]

APP_PATH    = File.expand_path("../", __dir__)
CONFIG_PATH = File.join(APP_PATH, "config/webpack/paths.yml")

begin
  paths = YAML.load(File.read(CONFIG_PATH))[NODE_ENV]

  NODE_MODULES_PATH   = File.join(APP_PATH.shellescape, paths["node_modules"])
  WEBPACK_CONFIG_PATH = File.join(APP_PATH.shellescape, paths["config"])

  WEBPACK_BIN       = "#{NODE_MODULES_PATH}/.bin/webpack-dev-server"
  DEV_SERVER_CONFIG = "#{WEBPACK_CONFIG_PATH}/development.server.js"
rescue Errno::ENOENT, NoMethodError
  puts "Configuration not found in config/webpacker/paths.yml."
  puts "Please run bundle exec rails webpacker:install to install webpacker"
  exit!
end

Dir.chdir(APP_PATH) do
  exec "NODE_PATH=#{NODE_MODULES_PATH} #{WEBPACK_BIN} --progress --color " \
    "--config #{DEV_SERVER_CONFIG}"
end

我收到此错误：

bundler: failed to load command: foreman (/Users/annie/.rbenv/versions/2.4.0/bin/foreman)

在细节上，我也可以看到这个并且不确定如何修复 bad URI(is not URI?): tcp://localhost:3000:5000 (URI::InvalidURIError) 如果我在不同的终端中分别运行Procfile中的2个命令（bin / rails s -b 0.0.0.0＆amp; bin / webpack-dev-server），那么一切正常（没有错误）

造成3000：5000的原因是什么？

我该如何解决？

非常感谢

确保没有在某处设置名为UTF-8的ENV变量。我使用gem dotenv-rails 时遇到了同样的问题。我的 .env 文件中有一行：

HOST

我摆脱了那条线，工头再次工作。

在Procfile
