ruby安裝的前提是要有rvm，rvm安裝更新操作詳見《Mac系統(tǒng)更新RVM到最新版本》
- 更新前記錄：
系統(tǒng)版本：macOS Catalina（10.15.5）
ruby版本：2.6.3p62
$ ruby -v
ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin19]
但是查詢已經(jīng)安裝的ruby時顯示并沒有安裝：
$ rvm list
# No rvm rubies installed yet. Try 'rvm help install'.
那么想要把當(dāng)前版本設(shè)為默認(rèn)版本，執(zhí)行命令也是不行：
$ rvm use 2.6.3 --default
Required ruby-2.6.3 is not installed.
To install do: 'rvm install "ruby-2.6.3"'
$ rvm use 2.6.3p62 --default
Required ruby-2.6.3p62 is not installed.
To install do: 'rvm install "ruby-2.6.3p62"'
兩個都不行，我也不懂，反正不行。 那就全部更新下到最新版本再說吧。
- 版本更新操作記錄：
1.列出 Ruby 可安裝的版本信息
$ rvm list known
2.安裝一個 Ruby 版本
$ rvm install 2.7.0
3.如果想設(shè)置為默認(rèn)版本，可以用這條命令來完成
$ rvm use 2.7.0 --default
按步驟查看當(dāng)前rvm可安裝的ruby版本如下：
$ rvm list known
# MRI Rubies
[ruby-]1.8.6[-p420]
[ruby-]1.8.7[-head] # security released on head
[ruby-]1.9.1[-p431]
[ruby-]1.9.2[-p330]
[ruby-]1.9.3[-p551]
[ruby-]2.0.0[-p648]
[ruby-]2.1[.10]
[ruby-]2.2[.10]
[ruby-]2.3[.8]
[ruby-]2.4[.9]
[ruby-]2.5[.7]
[ruby-]2.6[.5]
[ruby-]2.7[.0]
ruby-head
# for forks use: rvm install ruby-head-<name> --url https://github.com/github/ruby.git --branch 2.2
.

# IronRuby
ironruby[-1.1.3]
ironruby-head
查看到最新版本ruby版本是2.7，那就裝這個吧（時間賊久，裝了將近1個鐘頭 中間還發(fā)生失敗過一次，執(zhí)行原命令繼續(xù)下載）：

更新命令執(zhí)行結(jié)束， 那么來看下ruby版本和安裝信息：
$ ruby -v
ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-darwin19]
$ rvm list
=* ruby-2.7.0 [ x86_64 ]
# => - current
# =* - current && default
# * - default
這就算是更新成功過了。
