请问下我在fedora下交叉编译Qt时出现错误，详细信息为：
[root@localhost bin]# qtcreator &
bash: qtcreator: command not found
[1] 4857
[1]+ Exit 127 qtcreator
之后又重新设了环境变量，但还有错，为
[root@localhost bin]# gedit /etc/environment
[root@localhost bin]# qtcreator &
bash: qtcreator: command not found
[1] 5371
[1]+ Exit 127 qtcreator
这是怎么回事？
