client.c:439:3: error: use of undeclared identifier 'my_bool'

client.c:439:3: error: use of undeclared identifier 'my_bool',第1张

解决方式:

把mysql的gem版本换成0.5.2

再bundle

bundle完之後再改回原本的版本就不影响团队开发。

原则就是可以顺利跑完bundle就好,暂时更改版号骗过bundle

Gemfile

gem "mysql2", "~>0.5.2"

发生问题:

$ sudo gem install mysql2 -v 0.3.21
