【Sourcetree】解決閃退問題

作者: AMA 15 6 月, 2023

某天重開機之後就開不了 Sourcetree 了，查了一下發現應該是 Windows 更新導致的問題。

C:\Users\ama\AppData\Local\Atlassian\SourceTree\sourcetree.log 錯誤訊息如下：

最後成功的解法為刪除C:\Users\ama\AppData\Local\Atlassian\SourceTree.exe_Url_zeqdug2r5zpvv2zmyrbkerxd220ogx5n\3.4.8.0\Composition.cache

網路上還有看到幾種嘗試解法

取消 Windows Update
- 失敗，依然啟動不了程式
直接點擊執行檔
- C:\Users\ama\AppData\Local\SourceTree\app-3.4.8\SourceTree.exe
- 失敗
重新安裝 Sourcetree
- 需先刪除 C:\Users\ama\AppData\Local\SourceTree
- 需先刪除 C:\Users\ama\AppData\Local\Atlassian
- 這個我沒試過，但應該是最終手段了，真的其他方式都解決不了再使用這招吧！
