在Ubuntu虚拟机中使用GNURadio :致命错误

Question

我想在我的Ubuntu16.04虚拟机上试用GNURadio。我安装了osmosdr和osmosdr，实际上我尝试了这两个来源，但是我得到了这个错误：

Generating: '/home/natalia/Downloads/top_block_NoGUI.py'

Executing: /usr/bin/python -u 
/home/natalia/Downloads/top_block_NoGUI.py

Using Volk machine: avx2_64_mmx_orc
gr-osmosdr v0.1.4-98-gc653754d (0.1.5git) gnuradio 3.7.9
built-in source types: file fcd rtl_tcp rfspace redpitaya 

FATAL: No supported devices found to pick from.

Trying to fill up 1 missing channel(s) with null source(s).
This is being done to prevent the application from crashing
due to gnuradio bug #528.


>>> Done

我还将该文件创建为root: /etc/udev/ file es.d/20.rtlsdr.Rule，其中包含以下行：

SUBSYSTEM=="usb", ATTRS{idVendor}=="0bda", 
ATTRS{idProduct}=="2838", GROUP="adm", MODE="0666", 
SYMLINK+="rtl_sdr

因为当我这么做的时候，我得到：

我还能做什么呢？

您已经在没有rtlsdr支持的情况下安装了gr-osmosdr；对RTL dongles的本机支持不在gr-osmosdr提供的清单中。
