我正在尝试在渲染上部署仅包含 Rails api 的应用程序。当我进行更改并推送到 github 时，它会成功构建，但不会部署。错误是“./bin/rails：权限被拒绝” “未检测到开放端口”。可能出了什么问题？ 错误截图
这是我的 puma.rb 文件
# Puma can serve each request in a thread from an internal thread pool.
# The `threads` method setting takes two numbers: a minimum and maximum.
# Any libraries that use thread pools should be configured to match
# the maximum value specified for Puma. Default is set to 5 threads for minimum
# and maximum; this matches the default thread size of Active Record.
#

# Specifies the `worker_timeout` threshold that Puma will use to wait before
# terminating a worker in development environments.
#
worker_timeout 3600 if ENV.fetch("RAILS_ENV", "development") == "development"
# Specifies the `port` that Puma will listen on to receive requests; default is 3000.
#
port ENV.fetch("PORT") { 3001 }
# port ENV.fetch("PORT") { 10000 }
# Specifies the `environment` that Puma will run in.

# environment ENV.fetch("RAILS_ENV") { "development" }
environment ENV.fetch("RAILS_ENV") { "production" }
# Specifies the `pidfile` that Puma will use.
pidfile ENV.fetch("PIDFILE") { "tmp/pids/server.pid" }
# Specifies the number of `workers` to boot in clustered mode.
# Workers are forked web server processes. If using threads and workers together
# the concurrency of the application would be max `threads` * `workers`.
# Workers do not work on JRuby or Windows (both of which do not support
# processes).
#
workers ENV.fetch("WEB_CONCURRENCY") { 4 }
# Use the `preload_app!` method when specifying a `workers` number.
# This directive tells Puma to first boot the application and load code
# before forking the application. This takes advantage of Copy On Write
# process behavior so workers use less memory.

# Allow puma to be restarted by `bin/rails restart` command.

我尝试在 puma.rb 中设置端口。我已经尝试了两个端口
port ENV.fetch("PORT") { 3001 }
# port ENV.fetch("PORT") { 10000 } - render's default PORT
也尝试过这个
# environment ENV.fetch("RAILS_ENV") { "development" }
environment ENV.fetch("RAILS_ENV") { "production" }
这并没有解决问题
我解决了问题。
Puma.rb 正在 bin 文件夹中查找 /ruby.exe 文件而不是 /ruby。
所以我更新了 /bin/rails 文件
来自：
#!/usr/bin/env ruby.exe
APP_PATH = File.expand_path("../config/application", dir) require_relative“../config/boot” 需要“轨道/命令”
至：
#!/usr/bin/env ruby
APP_PATH = File.expand_path("../config/application", dir) require_relative“../config/boot” 需要“轨道/命令”
并更新了 render.build.sh
#!/usr/bin/env bash
设置-o errexit
捆绑安装 chmod +x bin/* 捆绑执行 rake db:migrate
这对我有用
