[英]Change Ruby Path without RVM
I'm not in the position to use RVM because I'm working with a predefined OS and a proxy. 我无法使用RVM,因为我正在使用预定义的OS和代理。
I'm working on CentOS7 and my application uses ruby 2.3.1
. 我正在使用CentOS7,我的应用程序使用
ruby 2.3.1
。 This comes pre-installed on this specific system. 它已预先安装在此特定系统上。 CentOS7 supports ruby up to
2.0.0
. CentOS7最多支持
2.0.0
ruby。
My problem is when I install KDE for a shell it installs ruby 2.0.0 and overrides certain paths so when I use ruby -v
I now use 2.0.0
which is not good! 我的问题是,当我为外壳安装KDE时,它将安装ruby 2.0.0并覆盖某些路径,因此当我使用
ruby -v
我现在使用2.0.0
,这不好!
If I do which -a ruby
I get 如果我这样做
which -a ruby
我得到的是which -a ruby
/usr/bin/ruby
/opt/rubies/ruby-2.3.1/bin/ruby
If I do echo $PATH
I get 如果我
echo $PATH
我得到
/opt/rh/rh-postgresql95/root/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/opt/rubies/ruby-2.3.1/bin:/usr/local/rvm/bin
The Ruby I want to use is installed in /opt/rubies/ruby-2.3.1/bin
but /usr/bin
comes before it. 我要使用的Ruby安装在
/opt/rubies/ruby-2.3.1/bin
但/usr/bin
位于它之前。 Is that the reason why CentOS7 is using that version of Ruby instead of the pre-installed Ruby 2.3.1 version in /opt/rubies/ruby-2.3.1/bin
? 这就是为什么CentOS7使用该版本的Ruby而不是/opt/rubies/ruby-2.3.1/bin中预先安装的Ruby 2.3.1版本的
/opt/rubies/ruby-2.3.1/bin
吗?
If so, how do I change the order of the path? 如果是这样,如何更改路径顺序?

Yes, it is the reason. 是的,这就是原因。

You can redefine the $PATH
in your ~/.bashrc
. 您可以在
~/.bashrc
重新定义$PATH
。 Just add this line at the bottom: 只需在底部添加以下行:
export PATH="/opt/rubies/ruby-2.3.1/bin:$PATH"
