从Meteor 2.2升级到2.7.3后无法启动：AccountsTemplates错误

升级Meteor至2.7.3版本前，先从项目中移除了useraccounts:core包，完成升级后重新添加该包，启动Meteor时出现以下报错：

尝试执行meteor add brettle:accounts-add-service解决时，遭遇版本冲突错误：

=> Errors while adding packages:             
                                            
While selecting package versions:
error: Conflict: Constraint accounts-base@1.2.0 is not satisfied by accounts-base 2.2.4.

解决步骤 #

执行以下命令即可恢复Meteor正常启动：

• meteor reset
• meteor add fetch
• meteor add accounts-ui
• meteor add service-configuration
• meteor add accounts-password
• meteor add accounts-ui

完成后Meteor可正常启动，仅需恢复本地数据库数据即可。
