设置 Rails 时 bundle install 抛出语法错误

设置 Rails 时 bundle install 抛出语法错误

我正在尝试将 Rails 应用程序部署到 Passenger。

运行 bundle 时：

[ps93785]$ /usr/lib/ruby/gems/1.8/bin//bundle install

我明白了：

Gemfile syntax error:
/home/djwyatt/supplies.mighty-wash.com/public/Gemfile:33: syntax error,
unexpected ':', expecting kEND
  gem 'sdoc', require: false

编辑1 如果 gem 文件为：，则为第 31-34 行：

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end

这在我的本地环境中运行得很好，知道为什么它会给我的 VPS 带来问题吗？

编辑2 （我使用 Ruby 2.0 进行开发，我的 VPS 是 1.8）

以下是我在尝试升级时遇到的问题：

[ps93785]$ rvm upgrade 2.0
The source ruby was not a valid ruby string.

1.9.3 也不起作用

编辑3 （这有效） rvm use 2.0 然后bundle install worked fantastic。现在有一个新问题 - 转储如下：

[ps93785]$ rake about

答案1

首先，您需要在 Gemfile 中使用 ruby​​ 1.8 语法：

group :doc do
  gem 'sdoc', :require => false
end

其次，我不确定 Passenger 的最新版本是否支持 Ruby 1.8。即使支持，您也应该至少升级到 ruby​​-1.9.3。
