我尝试使用 TexLive-Utility 更新 tlmgr，但找不到 kpsewhich。但我不确定为什么，因为它在我的 bash PATH 中
$which kpsewhich
/usr/texbin/kpsewhich
不仅如此，它位于 TeXLive-Utility 为其自身环境创建的 PATH 中，但日志文件显示两个不同的 PATH 变量……这是日志（删除了一些个人信息）

问题是：TexLive-Utility 在这里使用什么 PATH 变量（请注意，它在环境中列出了两次），以及当它组成了自己的环境时，我如何像 TeXLive-Utility 建议的那样“设置它”？
答案1
这应该是一个暂时的问题，并且已向 TeX Live 上游报告。TeX Live Utility 使用更新-tlmgr-最新版.sh进行更新，因为 存在历史问题tlmgr update --self。
作为 TLU 维护者，我建议用户等到服务器上修复它，但如果您急需某些包更新，您可以在终端中运行更新命令。
编辑：据 TeX Live 团队称，这个问题现已修复。修复版本现在应该在所有 CTAN 镜像上都有。
您可以通过按住 Option 键的同时选择“操作”菜单，然后选择“从关键存储库安装 TeX Live Manager”项来解决此问题。有些用户报告使用此方法下载失败。
现在应该将这个问题标记为非主题吗？大概比我得分高的人可以做到这一点……
