Ubuntu 14.04升级后如何让redmine更新?

Ubuntu 14.04升级后如何让redmine更新?

我无法更新我的 redmine。每次运行时apt-get upgrade,我都会收到 ruby​​ 未找到错误:

Setting up redmine (2.4.2-1) ...
dbconfig-common: writing config to /etc/dbconfig-common/redmine/instances/default.conf
Creating config file /etc/redmine/default/database.yml.new with new version
dbconfig-common: flushing administrative password
Populating database for redmine instance "default".
This may take a while.
/usr/bin/env: ruby1.8: No such file or directory
Error when running rake db:migrate, check database configuration.
dpkg: error processing package redmine (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 redmine
E: Sub-process /usr/bin/dpkg returned an error code (1)

我现在被困住了。我的 redmine 已经停止工作了。

我尝试通过将 /usr/bin/ruby1.8 链接到 /usr/bin/ruby 来进行“redmine”,但却遇到了不同的错误。

设置 redmine (2.4.2-1) ... dbconfig-common:将配置写入 /etc/dbconfig-common/redmine/instances/default.conf

然后我尝试按照建议重新安装 ruby​​1.8在这个问题上。但是在安装 ruby​​1.8 时我遇到了不同的错误。

apt-get install ruby1.8

显示的(第一条)错误消息是:

/usr/bin/env: ruby1.8: No such file or directory

正在尝试运行ruby1.8,但没有这样的程序。不幸的是,揭露通过“包裹内容”搜索,Ubuntu 14.04中不再提供ruby1.8。

仍然安装 ruby​​1.8:

您可以使用以下答案中描述的两种方法之一安装 ruby​​1.8:

目前有两个答案,一个建议启用 13.10 版的软件存储库来安装用于前一版本的旧版本,另一个建议使用(可能尤其是)实验性的 PPA

我不确定这两者中哪一个更好或更可靠。 任何一个都应该有效。

尝试将 ruby​​1.9 用作 ruby​​1.8:

另一种可能性,建议/启发自tres 的这个回答那个不同的问题堆栈溢出,就是“欺骗”redmine的安装脚本,让其将ruby的最新版本(ruby1.9)当做ruby1.8。这不会阻止ruby1.9为需要该版本的应用程序工作,但也不一定能正常工作;问题在于redmine对ruby1.8的依赖程度有多高。

为此,创建一个符号链接ruby(运行默认版本,在本例中为 1.9),名为ruby1.8

sudo ln -s /usr/bin/ruby /usr/bin/ruby1.8

(更新)如果你得到Could not find rake (>= 0) amongst [] (Gem::LoadError)

在添加到您的答案的更新信息中,您提到符号链接/usr/bin/ruby1.8/usr/bin/ruby使其使用已安装的 ruby​​1.9)并收到一条错误消息,其中第一个错误是:

/usr/lib/ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find rake (>= 0) amongst [] (Gem::LoadError)
        from /usr/lib/ruby/1.9.1/rubygems/dependency.rb:256:in `to_spec'
        from /usr/lib/ruby/1.9.1/rubygems.rb:1231:in `gem'
        from /usr/local/bin/rake:18:in `<main>'
Error when running rake db:migrate, check database configuration.

您可以通过安装该rake包来修复该错误:

sudo apt-get update
sudo apt-get install rake

如果符号链接ruby1.8不起作用ruby,您决定尝试实际安装 ruby​​1.8,则应先使用 删除链接sudo rm /usr/bin/ruby1.8

如果您还有其他问题,请编辑您的问题并提供详细信息。(或者,如果您觉得问题与您在此处询问的问题有很大不同,您可以提出新问题。)祝您好运。

答案2

尝试了不同的解决方案后,还是无法正确安装 redmine。我终于在另一台机器上让它工作了。并使用以下步骤。

  • 备份mysql上的redmine_default数据库,并在另一台同名机器上恢复
  • 在新机器上全新安装 redmine。

    apt-get 安装 redmine redmine-mysql

  • 按照 redmine 安装步骤这里

安装/升级顺利进行,我现有的所有数据均完好无损。

几天后,我在旧机器上又做了一次测试,发现通过卸载 redmine 并清除它,确保删除了以前的 redmine 和 ruby​​ 的所有痕迹,然后从头开始重新安装它,就可以了!!!

因此,如果升级有问题,请备份数据库,卸载 redmine

apt-get remove redmine redmine-mysql
apt-get purge redmine redmine-mysql

恢复数据库,并按照上面的安装
