问题描述
我是 Rails 的新手,我已经关注了 Ruby onRails 教程 的大部分内容.从那以后,我决定制作自己的应用程序,但使用测试版的 Rails 4 gem.我已经在我的本地机器(Windows 7)上安装了 PostgreSQL 并完成了开发.一切都很好!(我喜欢 Rails 远胜过我以 C#、ASP、.NET 为生的工作!)
I'm pretty new to Rails here and I've followed Ruby on Rails Tutorial for most of it. I have since decided to make my own application, but using the Rails 4 gem in beta. I have installed PostgreSQL on my local machine (Windows 7) and done development. Everything works great! (I love Rails much more than C#, ASP, .NET work that I do for a living!)
然而,一旦我决定推进 Heroku,我就一直在努力.在推送到 Heroku 之前,我做了标准:
However, once I decided to push to Heroku, I've been pulling my hair out. Prior to pushing to Heroku, I did the standard:
c:Siteselms>git add .
c:Siteselms>git commit -m "My comment"
c:Siteselms>git push
c:Siteselms>git push heroku master
我已经下载并安装了 Heroku Toolbelt(不是 heroku
gem.)第一个错误告诉我我需要确保我的 Gemfile
指定了 Ruby >= 1.9.3,所以我在 Gemfile
的顶部添加了ruby 1.9.3":
I've downloaded and installed the Heroku Toolbelt (not heroku
gem.) The first error told me I needed to make sure that my Gemfile
specified Ruby >= 1.9.3, so I added "ruby 1.9.3" to the top of my Gemfile
:
source 'https://rubygems.org'
ruby "1.9.3"
gem 'rails', '4.0.0.beta1'
gem 'pg'
gem 'haml-rails'
gem 'httparty'
gem 'devise', git: 'git://github.com/plataformatec/devise.git', branch: 'rails4'
gem 'cancan'
gem 'bootstrap-sass'
gem 'formtastic'
gem 'formtastic-plus-bootstrap'
group :development do
gem 'annotate'
gem 'better_errors'
gem 'binding_of_caller'
gem 'guard-spork'
gem 'guard-rspec'
gem 'meta_request'
gem 'rb-notifu'
gem 'schema_to_scaffold'
gem 'wdm', :platforms => [:mswin, :mingw], :require => false
gem 'win32console'
end
group :development, :test do
gem 'rspec-rails'
gem 'pry'
gem 'spork-rails', git: 'git://github.com/sahilm/spork-rails.git', branch: 'rails-4'
gem 'spork', '~> 1.0.0rc3'
end
group :test do
gem 'capybara'
gem 'factory_girl_rails'
gem "shoulda-matchers"
end
group :assets do
gem 'sass-rails', '~> 4.0.0.beta1'
gem 'coffee-rails', '~> 4.0.0.beta1'
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 1.0.1'
推送终于成功了,没有任何问题,但是当我尝试迁移数据库时,我得到以下信息:
The push finally worked without any issues, but when I tried to migrate the database, I got the following:
c:Siteselms>heroku run rake db:migrate
Running `rake db:migrate` attached to terminal... up, run.2205
/usr/bin/env: ruby.exe: No such file or directory
我也试过:heroku run bin/rake db:migrate
,它给出了同样的错误.我正在使用 Heroku 上的 Rails 4.x 入门 将我的 Rails 4 应用程序推送到 Heroku.任何帮助将不胜感激!
I have also tried: heroku run bin/rake db:migrate
, and it gives same error. I am using Getting Started with Rails 4.x on Heroku to push my Rails 4 app to Heroku. Any help would be greatly appreciated!
哦,我运行后也有问题:
Oh, I also had an issue after running:
c:Siteselmx>gem install rails --pre
我通过将 C:RailsInstallerRuby1.9.3libubygems1.9.1in;
添加到 Windows 7 中的环境路径变量来解决这个问题(它给了我一个尝试执行任何操作时找不到 rails 的错误,例如:
I solved this by adding C:RailsInstallerRuby1.9.3libubygems1.9.1in;
to my environment Path variable in Windows 7 (it was giving me an error that it couldn't find rails when trying to execute anything such as:
rails -v
rails g controller User
但如果我只输入:
rails
它会给我所有我可以使用的命令(就像运行 rails -h
)
It would give me all of the commands I could use (as if running rails -h
)
我使用 Windows Rails 安装程序设置了我的机器,然后安装了 Rails 4 gem.这非常令人沮丧,我已经在互联网上搜索并试图找到有同样问题的人.
I set up my machine by using the Windows Rails Installer, then installing the Rails 4 gem. This is extremely frustrating and I've scoured the internet trying to find someone with the same problem.
编辑 1:
我刚刚删除了我的用户 Path 环境变量并将我的系统 Path 环境变量修改为如下所示:
I just deleted my user Path environment variable and modified my system Path environment variable to look like such:
C:RailsInstallerRuby1.9.3in;C:RailsInstallerRuby1.9.3lib
ubygems1.9.1in;C:Program Files (x86)gitcmd;C:Program Files (x86)Herokuin
将我的路径变量更新为上述内容并卸载 Heroku Toolbelt,然后重新安装它(因此 Heroku 部分位于路径变量中)并尝试以下操作:
Updated my path variable to the above and uninstalled Heroku Toolbelt, then re-installed it (hence why the Heroku piece is in the path variable) and tried the following:
c:Siteselms>ruby -v
ruby 1.9.3p125 (2012-02-16) [i386-mingw32]
c:Siteselms>rails -v
Rails 4.0.0.beta1
c:Siteselms>heroku -v
! `-v` is not a heroku command.
! Perhaps you meant `-h`.
! See `heroku help` for a list of available commands.
c:Siteselms>heroku run rake db:migrate
Running `rake db:migrate` attached to terminal... up, run.2100
/usr/bin/env: ruby.exe: No such file or directory
c:Siteselms>heroku run bin/rake db:migrate
Running `bin/rake db:migrate` attached to terminal... up, run.2872
/usr/bin/env: ruby.exe: No such file or directory

所以我在这次冒险中走得更远.我发现我可以执行:
So I got a little further in this venture. I found out that I could execute:
c:Siteselms>heroku run bash
~ $ cd bin
~/bin $ ruby rake db:migrate
然后运行 rake 并在 Heroku 上迁移我的数据库.但是问题越来越严重!我尝试导航到该页面,它告诉我有问题,所以我运行日志文件,这就是我得到的:
And that would then run rake and migrate my database on Heroku. But the problem gets worse! I try to navigate to the page and it tells me that there is something wrong, so I run the log file and this is what I get:
c:Siteselms>heroku logs

这真的很令人沮丧.我不知道 /usr/bin/env
是什么鬼东西.我唯一能猜到的是它就像 Windows 的 PATH
.如果是这样,为什么服务器不知道 ruby.exe
在哪里?
This is getting really frustrating. I have no clue what the heck /usr/bin/env
is. The only thing I can guess is that it's like PATH
for Windows. If this is the case, why does the server not know where ruby.exe
is?
我确实制作了一个非 Rails 4 应用程序,并且能够将它发布到 Heroku 并毫无问题地查看它.这真的让我很紧张.
I did make a non Rails 4 application and was able to post it to Heroku and view it with no issues. This is really getting on my nerves.
推荐答案
您需要在您的应用程序中更改第一行的 3 个文件:
You need to change in your application first line of the 3 files:
bin/bundle
bin/rails
bin/rake
代替
#!/usr/bin/env ruby.exe
必须
#!/usr/bin/env ruby
这就是错误的原因:
/usr/bin/env: ruby.exe: No such file or directory
那么你就成功了:
heroku run rake db:migrate
这对我有用.
