之前下载go 的mysql包时，是如下方式，
$ go get github.com/Go-SQL-Driver/MySQL
不过现在这么执行会报错误如下：
Username for 'https://github.com': ghj1976
Password for 'https://ghj1976@github.com':
# cd .; git clone https://github.com/Go-SQL-Driver/MySQL /Users/cybercare/go/src/github.com/Go-SQL-Driver/MySQL
Cloning into '/Users/cybercare/go/src/github.com/Go-SQL-Driver/MySQL'...
fatal: https://github.com/Go-SQL-Driver/MySQL/info/refs?service=git-upload-pack not found: did you run git update-server-info on the server?
package github.com/Go-SQL-Driver/MySQL: exit status 128
go get 下载方式改成小写后，则没有任何问题，直接就可以了。
go get github.com/go-sql-driver/mysql
这个包的Readme中现在也修改成用小写方式go get 了。
