记录ruby的一些报错

错误

Could not find a valid gem 'pumagem' (>= 0) in any repository

ERROR:  Could not find a valid gem 'pumagem' (>= 0) in any repository

ERROR:  Possible alternatives: cutagem, mutagem

镜像源的问题,替换成ruby-china就好了

# gem -v

2.7.8

# gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/

https://gems.ruby-china.com/ added to sources

source https://rubygems.org/ not present in cache

# gem sources -l

*** CURRENT SOURCES ***

https://gems.ruby-china.com/

Your Gemfile lists the gem paranoia (~> 2.2) more than once.

[root@izuf63g0jydq42k49eo7zcz config]# bundle install

Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application for all non-root users on this machine.

Your Gemfile lists the gem paranoia (~> 2.2) more than once.

You should probably keep only one of them.

While it's not a problem now, it could cause errors if you change the version of one of them later.

Your Ruby version is 2.5.3, but your Gemfile specified 2.5.1

我的Gemfile中指定的版本是2.5.1但是系统中ruby的实际版本是2.5.3,两种解决办法

1. 强制执行

2. 修改Gemfile.lock和Gemfile中的ruby版本,更改成系统中的版本

3. 将ruby版本回退到项目需要的版本
