Error: 'git' not in PATH（nim学习系列）
某日在一台windows 7 上安装nim lang，然后安装第一个包就报错了。
C:\Users\user>nimble install winim --verbose
Reading official package list
Downloading https://github.com/khchen/winim using git
Error: 'git' not in PATH.
随后全盘搜索也没发现“git.exe”，只能重新安装git。然后再次安装winim，发现可以了。
C:\Users\user>nimble install winim
