我想从python调用来自Ubuntu 18.04上的PyCharm CE 2019.2的gnuradio 3.8中的块。 在 Pycharm 中设置的项目解释器是在创建 pycharm 项目时创建的虚拟环境。 我看到了建议(如何在pycharm中导入模块？(添加如下行：
/home/my_name/devel/gnuradio3_8/lib/python3.6/dist-packages
到解释器路径(在文件->设置->项目：my_proj->项目解释器->齿轮符号->显示全部>显示所选解释器的路径(下(。
在python控制台中，当我尝试导入gnuradio块时，这会导致以下错误：

导入 gnuradio 的正确方法是什么？
ImportError： libgnuradio-blocks.so.3.8.0： 無法打開共享目標檔案： 沒有這樣的文件或目錄
是的。我在通常的地方有 gnuradio3.7,3.8 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，但是您可以从您的终端执行
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/devel/gnuradio3_8/lib
然后从同一终端启动 pycharm 或将其添加到您的~/.bash_profile
如果您使用pybombs安装了gnuradio，则可以从终端获取~/devel/gnuradio3_8setup_env.sh脚本
$ source setup_env.sh
