命令在使用sudo运行时未找到。

Question

我安装了TexLive 2021，并通过更新~/.bashrc文件来设置路径。因此，我可以运行所有命令，但不能使用sudo：

~$ tlmgr install book
You don't have permission to change the installation in any way,
specifically, the directory /usr/local/texlive/2021/tlpkg/ is not writable.
Please run this program as administrator, or contact your local admin.
tlmgr: An error has occurred. See above messages. Exiting.
~$ sudo tlmgr install book
sudo: tlmgr: command not found

这怎么可能呢？

Answer 1

尝试tlmgr的完整路径，即

sudo /usr/local/bin/tlmgr install book

调整设置的路径。
