How to switch bundler version?
问题 I thought the below command would switch bundler installation, but it actually raised an error. $ bundle _1.10.6_ -v Could not find command "_1.10.6_". $ bundle -v Bundler version 1.13.6 $ gem list | grep bundle bundler (1.13.6, 1.10.6) What should I do? 回答1: To use different gem versions, you could use this pattern: your-gem _version_ . For example, bundle _1.10.6_ -v . Hope that will help. 来源: https://stackoverflow.com/questions/41500197/how-to-switch-bundler-version
