1.下载

腾讯软件中心下载地址：https://pc.qq.com/detail/17/detail_23237.html

或者sourceTree官网下载：https://www.sourcetreeapp.com/

2.安装

安装包下载之后，双击打开，会出现如下界面(3.2.6版本)：

此时提示需要登陆，放着不管，需要再做两件事：

2.1.添加一个 accounts.json 文件

用文件管理器打开 %LocalAppData%\Atlassian\SourceTree  目录（输入，回车即可），在该目录中添加 accounts.json 文件，内容为：

[{"$id": "1","$type": "SourceTree.Api.Host.Identity.Model.IdentityAccount, SourceTree.Api.Host.Identity","Authenticate": true,"HostInstance": {"$id": "2","$type": "SourceTree.Host.Atlassianaccount.AtlassianAccountInstance, SourceTree.Host.AtlassianAccount","Host": {"$id": "3","$type": "SourceTree.Host.Atlassianaccount.AtlassianAccountHost, SourceTree.Host.AtlassianAccount","Id": "atlassian account"},"BaseUrl": "https://id.atlassian.com/"},"Credentials": {"$id": "4","$type": "SourceTree.Model.BasicAuthCredentials, SourceTree.Api.Account","Username": "","Email": null},"IsDefault": false}
]

2.2.修改  user.config 文件

找到 %LocalAppData%\Atlassian\SourceTree.exe_Url_xxxxxxxxxx\3.1.2.3027\user.config 文件，记事本或者其他编辑工具打开，在该文件 <SourceTree.Properties.Settings>  添加以下内容并保存

<setting name="AgreedToEULAVersion" serializeAs="String"><value>20160201</value>
</setting>

重新打开 SourceTree，即为已登陆状态，下一步即可。

注：mac版本跳过登陆的方法更加简单，详见我的另一篇文章：Mac版sourceTree跳过登录
