这三点都试过确认了，问题还是没有解决，很奇怪

I see.

If you just enter qrc at command line, you will get the same warning message as OP.  This is expected.  qrc requires several command line options.  If no option is provided, you get the warning message.
Try:
qrc -h
This will show you a list of command line options.

As long as you see Quantus menu in Virtuoso Layout Editor, it should be OK.

我查看了，看起来是需要一个required QRC command file ？其他的似乎不是必须的。这个command file 您了解吗？

Quantus command file又称为ccl，从头开始写会很烦，最好找一个以前就用过的做模板。

如果用Innovus，可以在Innovus里直接调用Quantus生成SPEF，不用在命令行独立跑qrc，可以参考我的日志 - Innovus调用Quantus QRC。
如果还是想在命令行单独跑qrc，有一个办法可以快速生成ccl。在Innovus里调用qrc后工作目录下会有一个 qrc_*.log。打开这个文件，从extract开始就是ccl，copy出来当ccl模板。
Have fun!

*WARNING* QRC_HOME environmental variable is set but UI can't locate correct QRC installation.
In order to run UI in QRC compatibility mode you need to have QRC executables in your $PATH and QRC version should be 8.1 or greater.
Check your QRC installation and environmental settings.
环境是设置过的
export QRC_HOME=/opt/eda/cadence/EXT151
export PATH=$PATH

QRC_HOME/bin
export QRC_ENABLE_EXTRACTION=t
