我的ruby应用程序正在AmazonLinux2ElasticBeanstalk中运行。当我将应用程序部署到环境中时，它会告诉我bunlder没有安装。我在安装bundler时遇到以下错误， sudo gem 也不行

[ec2-user@ip-10-0-2-220 ~]$ gem install bundler
ERROR:  While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /opt/rubies/ruby-2.7.4/lib/ruby/gems/2.7.0 directory.
[ec2-user@ip-10-0-2-220 ~]$ sudo gem install bundler
sudo: gem: command not found

您能告诉我如何获得写入权限吗？

ruby amazon-web-services

您可以尝试以下几种可能性：

i: change permission of the directory 
[ec2-user@ip-10-0-2-220 ~]$ chmod 777 -R /opt/rubies/ruby-2.7.4/lib/ruby/gems/2.7.0

[ec2-user@ip-10-0-2-220 ~]$ gem install bundler

这会给你所有的权限（如果它不允许你的话，你可以使用sudo chmod）到这个目录

ii. get the path of gem and create a sym link to it in /bin 
then sudo gem command would work for you. 

to know the gem binary path just do 

[ec2-user@ip-10-0-2-220 ~]$ type gem

this would return you current gem binary path

create a sym link  
[ec2-user@ip-10-0-2-220 ~]$ ln -s gempath /bin/gem 
( gempath here is the output of "type gem" command)

and then "sudo gem install blunder" should work
