在Mac OS High Sierra上升级Ruby的最有效方法是什么?
我正在尝试将简单的Ruby应用程序部署到Heroku。
我正在运行命令:
performance-schema=0
symbolic-links=0
performance-schema=0
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
default-storage-engine=MyISAM
innodb_file_per_table=1
max_allowed_packet=268435456
open_files_limit=10000
innodb_buffer_pool_size = 256M
#tmp_table_size = 50M
#max_heap_table_size = 40M
join_buffer_size= 256K
query_cache_size = 128M
query_cache_type = 1
但是,出现以下错误:

Heroku不支持Ruby 2.3.3
Heroku支持以下Ruby版本和关联的Rubygems。受支持的版本意味着您可以期望我们的工具和平台可以与给定的版本一起使用。这也意味着您可以获得技术支持。这是我们支持的Ruby版本:
MRI:
- 2.4.5:补丁程序级别335,Rubygems:2.6.14.3
- 2.5.3:补丁程序级别105,Rubygems:2.7.6
- 2.6.0:补丁程序级别0,Rubygems:3.0.1
还读取了信息how to specify Ruby version。

在此链接https://devcenter.heroku.com/articles/ruby-support#supported-runtimes中查看红宝石的最新版本
然后运行最新的rvm install ruby-2.4.6
在终端中输入ruby -v
,您应该会看到ruby 2.4.6。
如果仍然显示ruby 2.0,请运行rvm use ruby-2.4.6 --default
。
这解决了我的问题
