python - 在 ubuntu 上使用 pycharm 时导入 gnuradio

问题描述

我想在 Ubuntu 18.04 上从 PyCharm CE 2019.2 从 python 调用 gnuradio 3.8 中的块。Pycharm中设置的项目解释器是创建pycharm项目时创建的虚拟环境。我已经看到建议（如何在 pycharm 中导入模块？）添加如下一行：

/home/my_name/devel/gnuradio3_8/lib/python3.6/dist-packages

到解释器路径（在 File->Settings->Project:my_proj->Project Interpreter->Gear Symbol->Show All->Show Paths for Selected Interpreter 下）。

从 python 控制台，当我尝试导入 gnuradio 块时，这会导致以下错误：

我相信我已经安装了 libgnuradio：

导入gnuradio的正确方法是什么？

解决方案

ImportError：libgnuradio-blocks.so.3.8.0：无法打开共享对象文件：没有这样的文件或目录

是的。我在通常的地方有 gnuradio3.7，而 3.8 在我的主目录下

您需要将已安装 gnuradio libs ( ~/devel/gnuradio3_8/lib) 的路径添加到LD_LIBRARY_PATH环境变量中。

我不熟悉 pycharm，但你可以从你的终端执行

$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/devel/gnuradio3_8/lib

然后从同一个终端启动 pycharm 或将其添加到您的~/.bash_profile

如果您已gnuradio使用安装pybombs，将有一个setup_env.sh脚本~/devel/gnuradio3_8，您可以从终端获取

$ source setup_env.sh
