1. 下载并安装好Git
2. 打开目录C:\Users\XXXX\AppData\Local\Atlassian\SourceTree，XXXX为你当前的用户目录，创建并修改accounts.json文件如下

   [
     {
       "$id": "1",
       "$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. 打开C:\Users\XXXX\AppData\Local\Atlassian\SourceTree.exe_Url_wqdtv3oppzegezgocz22bstjv2dynnpc（该目录可能不一致，找到以SourceTree.exe_Url_开头的即可。）
   接着进入”3.1.3.3158“目录，打开user.config文件，在SourceTree.Properties.Settings代码块内加入如下代码。

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

4. 运行SourceTree安装文件，即可
