ubuntu使用pycharm时在导入python-kafka库后没显示kafka

可能是因为PyCharm中的Python解释器没有安装python-kafka库的原因。你可以尝试在PyCharm中打开Project Interpreter，检查是否安装了python-kafka库。如果没有安装，你可以通过以下步骤安装： 1. 打开PyCharm并打开你的项目。 2. 点击菜单栏上的“File” -> “Settings” -> “Project: your_project_name” -> “Project Interpreter”。 3. 在右上角的“+”按钮中搜索“kafka”。 4. 安装“kafka-python”库，并等待安装完成。 安装完成后，你应该能够在PyCharm中看到python-kafka库并使用它来编写代码了。
