1. 找到 C:\Users\Administrator\AppData\Local\Atlassian\SourceTree 在这个目录下，添加一个 accounts.json文件
2.文件内容如下：
[
{
"$id":"1",
"$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 }
]
3.重启sourcetree, 如果遇到检测不到git，在 工具=》选项中 设置git启用
