问题

运行时rvm rubygems latest我收到此错误:

Error running 'env GEM_PATH=/Users/sjc/.rvm/gems/ruby-2.0.0-p0:/Users/
sjc/.rvm/gems/ruby-2.0.0-p0@global:/Users/sjc/.rvm/gems/ruby-2.0.0-p0:

jc/.rvm/src/rubygems-2.0.0/setup.rb', please read /Users/sjc/.rvm/log/
ruby-2.0.0-p0/rubygems.install.log

日志(rubygems.install.log)有这个:

RubyGems 2.0.0 installed

因为我不知道自己在做什么,所以我认为我早先尝试安装sass可能会导致这种情况.我按照这些说明操作,从而在当天早些时候执行这些命令.

$ export GEM_HOME=/home/mygemrepository
$ ruby setup.rb --prefix=/home/mystuff

同样,如果GEM_HOME和GEM_PATH看起来正确那么重要.

$ echo $GEM_HOME
/Users/sjc/.rvm/gems/ruby-2.0.0-p0
$ echo $GEM_PATH
/Users/sjc/.rvm/gems/ruby-2.0.0-p0:/Users/sjc/.rvm/gems/ruby-2.0.0-p0@global 

有什么我可以/应该做的成功安装rubygems？

Answer 1

示例为 ruby​​ 2.3.1，或者可能是其他版本的 ruby​​。

无需重新安装rvm：

rvm pkg install openssl
rvm install 2.3.1 --with-openssl-dir=$HOME/.rvm/usr

或者重新安装rvm：

rvm implode
\curl -sSL https://get.rvm.io | bash
rvm pkg install openssl
rvm install 2.3.1 --with-openssl-dir=$HOME/.rvm/usr

或者使用 ruby​​ < 2.3 的自定义 ruby​​gems：

rvm pkg install openssl
rvm install 2.2.2 --rubygems 2.7.10 --with-openssl-dir=$HOME/.rvm/usr

PS：毕竟可能会重新安装所有ruby版本

rvm reinstall all --force

看起来你错过了openssl.结帐:https://rvm.io/packages/openssl/
