ModuleNotFoundError：沒有名為“gnuradio”的模塊

Question

我正在嘗試在我的 ubuntu 20.02 上使用https://github.com/rpp0/gr-lora安裝 gr-lora。 我已經從安裝部分成功安裝了 docker 工具箱。 但隨后嘗試測試部分它有命令 $./lora_receive_file_nogui.py 基本上用於測試安裝。 When I run to run that.py file it showed me error "ModuleNotFoundError: no module named 'gnuradio'. Then I tried to install gnuradio for ubuntu. One of the source also suggested me to use python 2.7 instead of python 3. I tried一切，但它仍然向我顯示同樣的錯誤。有人可以幫我解決這個問題嗎？

Answer 1

當我運行該 .py 文件時，它向我顯示錯誤“ModuleNotFoundError：沒有名為 'gnuradio' 的模塊。

您需要在容器內而不是在您的主機中執行./lora_receive_file_nogui.py 。

我只是對其進行了幾次測試，它大部分都按照文檔說明工作——有時在第一次運行時它不會解碼任何東西，但在第二次運行時你會收到很少的消息。 這是我的一項測試的完整 output。
