使用Choco安装Tabby时校验和不匹配的问题排查与解决咨询

我来帮你分析这个校验和不匹配的问题，以及对应的解决办法：

你在执行Choco安装Tabby时遇到了哈希值不匹配的错误，终端输出如下：

PS C:\Users\devpa> choco install tabby -y

Consider passing the actual checksums through with --checksum --checksum64 once you validate the checksums are appropriate. A less secure option is to pass --ignore-checksums if necessary.

原因分析 #

出现这个错误主要有几个常见原因：

• 安装包哈希值变更：Tabby官方可能重新上传了同版本号的安装包（比如修复了某个小问题但没改版本号），导致实际下载文件的哈希值和Chocolatey包中预设的不一致
• 下载文件损坏：虽然显示下载完成，但网络波动等原因导致文件不完整，哈希值自然不匹配
• Chocolatey包维护滞后：Tabby的Chocolatey包维护者还没同步更新最新的安装包哈希值

解决办法 #

1. 使用实际校验和强制安装（推荐）

终端已经给出了实际下载文件的SHA256哈希值，你可以直接指定这个值来让Chocolatey通过校验：

choco install tabby -y --checksum64=7112B623A885DE4C669846469C75A4AF1F0562941201DDF0EDA1E87ADA2FAC4D

2. 临时忽略校验和（仅应急使用）

如果你确认下载的安装包是安全可信的，可以临时跳过校验和检查，但这个方法会降低安全性，不建议常用：

choco install tabby -y --ignore-checksums

3. 手动下载后本地安装

你也可以自己下载安装包，再用Chocolatey本地安装：

• 先从Tabby官方渠道下载对应版本的安装包
• 执行本地安装命令（替换路径为你下载文件的实际位置）：

choco install tabby -y --source="C:\Users\devpa\Downloads\tabby-1.0.197-setup-x64.exe"

4. 反馈问题给包维护者

如果是因为Chocolatey包的哈希值未更新，你可以去Tabby的Chocolatey包页面提交问题，提醒维护者更新正确的校验和，帮助后续用户避免同样的问题。
