我是在文件夹中用终端找回的，在发送失败那里新建了个(debug写失败)分支，结果12e6e83、149980c就没了，找不回来了，到终端中操作一番才找回。（三年了，都没人回复，是都会还是什么？） $ git reflog 134c3e3 (HEAD -> master, debug写失败) HEAD@{0}: checkout: moving from debug写失败 to master 134c3e3 (HEAD -> master, debug写失败) HEAD@{1}: reset: moving to 134c3e3a18d85656b2ac709a3d0661ac861d801e 8eee70f HEAD@{2}: reset: moving to 8eee70f25a73b5c0db09c8f36c90dff15f810422 134c3e3 (HEAD -> master, debug写失败) HEAD@{3}: checkout: moving from master to debug写失败 134c3e3 (HEAD -> master, debug写失败) HEAD@{4}: reset: moving to 134c3e3a18d85656b2ac709a3d0661ac861d801e 149980c HEAD@{5}: commit: 发送失败 134c3e3 (HEAD -> master, debug写失败) HEAD@{6}: reset: moving to 134c3e3a18d85656b2ac709a3d0661ac861d801e 12e6e83 HEAD@{7}: commit: 一直发送失败 134c3e3 (HEAD -> master, debug写失败) HEAD@{8}: commit: 基本能用了 977072a HEAD@{9}: commit: 固定了UUID 22838fa HEAD@{10}: commit: 蓝牙收发功能可用 a262052 HEAD@{11}: commit: 设备搜索基本完成 8eee70f HEAD@{12}: commit (initial): 搭建出了框架 Dell@DESKTOP-NNG7FQJ MINGW64 /d/project/wechatproj/bmsdata (master) $ git reset --hard 1499 HEAD is now at 149980c 发送失败
