Ubuntu 10 Ruby 1.9 Rails 3:没有这样的文件或目录 [英] Ubuntu 10 Ruby 1.9 Rails 3: No such file or directory
问题描述
我已经为此苦苦挣扎了一段时间.我在装有 ruby 1.8 的开发机器上运行 Ubuntu 10，我删除了.我使用RVM和本教程http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/
I have been struggling with this for quite some time now. I'm running Ubuntu 10 on the dev machine which had ruby 1.8 on it, which I removed. I installed Ruby 1.9.3 and rails3 using RVM and this tutorial http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/
当我输入 ruby -v 我得到
ruby 1.9.3p125 (2012-02-16 revision 34643) [i686-linux]
这似乎是正确的.
我使用
rails new mysite
成功创建了新应用.然后我
which created the new app successfully. then I
cd mysite
并创建了一个宝石组
rvm gemset create 'rails3'
然后我在/mysite/文件夹中使用了这个
then I used this inside the /mysite/ folder
rvm use 1.9.3@rails3 --rvmr
Using /usr/local/rvm/gems/ruby-1.9.3-p125 with gemset rails3
但是当我尝试运行它时出现问题
root@server-pc:/var/www/mysite# rails s
-bash: /usr/bin/rails: /usr/bin/ruby1.8: bad interpreter: No such file or directory
编辑 1:
root@server-pc:/var/www/mysite# which ruby
/usr/local/rvm/rubies/ruby-1.9.3-p125/bin/ruby
推荐答案
以root用户
log in as root user
列出红宝石包
list ruby packeges
dpkg -l | grep ruby
然后删除所有 ruby 包
then remove all ruby packeges
aptitude purge <package name>
如果你安装了rvm
rvm remove all
然后
rvm implode
或
rvmsudo rvm implode
<小时>
安装红宝石
仍以 root
安装所有必要的工具和库
install all of the necessary tools and libraries
apt-get install curl git-core build-essential zlib1g-dev libssl-dev libreadline5-dev
安装 rvm
bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
然后添加这一行作为 .bashrc 中的最后一行:
Then add this line as the last line in your .bashrc:
nano ~/.bash_profile
if [[ -s "$HOME/.rvm/scripts/rvm" ]] ; then source "$HOME/.rvm/scripts/rvm" ; fi
测试 RVM 安装
rvm notes
接下来，您可以通过运行开始 ruby 1.9.2 安装
Next, you can begin ruby 1.9.2 installation by running
rvm install 1.9.2
安装最多需要几分钟，一旦完成，您必须将 ruby 1.9.2 设置为默认版本
The install will take up to several minutes and once it completes you have to set ruby 1.9.2 as the default version
rvm --default ruby-1.9.2
测试你的新 ruby 安装ruby -v
test your new ruby install ruby -v
安装 Rails 3
gem install rails
如果您想使用 sqlite 快速启动并运行数据库，则需要 sqlite3 和 libsqlite3-dev 软件包
If you want to get a quick database up and running with sqlite, then you’ll need to sqlite3 and the libsqlite3-dev packages
apt-get install sqlite3 libsqlite3-dev
gem install sqlite3-ruby
创建新应用
rails new testapp
cd testapp
确保您在测试应用程序目录中并运行
Make sure you are in your test app directory and run
rails s
