未找到命令/使用“bundle install”安装缺少的 gem 二进制文件使用自动测试

Question

I am totally new to RoR. I am following Michael Hartl's book. I am not able to make autotest run.请提出问题所在以及解决方案。

When I run 'autotest' at command line inside Rails project directory i get following:

-bash: autotest: command not found

When I run 'bundle exec autotest' I get following:

 bundler: command not found: autotest
 Install missing gem binaries with `bundle install'

Here is the Gemfile

source 'http://rubygems.org'

gem 'rails', '3.0.3'
gem 'sqlite3-ruby', :require => 'sqlite3'

group :development do
gem 'autotest'
gem 'rspec-rails', '2.4.1' 
end

group :test do
gem 'rspec', '2.4.0'
gem 'webrat', '0.7.1'
end

Answer 1

bundle install --binstubs 会将捆绑包中的所有可执行文件安装到项目中的本地 bin 目录中（请参阅 http://gembundler.com/），然后你可以运行./bin/autotest。

Answer 2

只需重新启动终端选项卡并重试即可。那应该解决它。

Answer 3

我遇到了类似的错误

bundler: command not found: thin
Install missing gem executables with `bundle install`

运行以下命令添加了所需的 gem：

bundle install --deployment

Answer 4

确保将自动测试命令放入测试块中。您似乎只在开发区拥有它。然后，进行捆绑安装

Answer 5

对于rvm的用户：

$ rvm gemset create myapp
$ bundle install

为我工作。

Answer 6

我遇到了同样的问题，但我按照这些步骤下载了 mysql。此链接向您展示了如何操作。 mysql
现在我在重置密码时遇到了问题，但是一旦您打开第二个下载文件，您就必须输入临时密码，然后它会要求您更改密码。
