Variables 如何成功启动vsim命令？即使它位于CentOS 8中的PATH环境变量中，也找不到它,variables,path,command,environment,Variables,Path,Command,Environment,当我尝试运行/vsim命令时，如何使其被识别？它位于$PATH变量中，但如果我在其路径之外，它将拒绝运行，如您在以下代码中所看到的： [x@localhost /]$ echo "$SHELL" /bin/bash [x@localhost ~]$ cat /home/x/.bashrc # .bashrc # Source global definitions if [ -f /etc/bashrc ]; then . /etc/bashrc fi # User

正如您所看到的，当我将

放入存储vsim文件的文件夹时，它确实起作用

有人知道为什么CentOS 8不识别

/tools/Questasim/Questasim/linux\u x86\u 64

，即使它位于

$PATH

环境变量中
