我要求我尝试以root用户身份安装它或使用命令sudo尝试安装软件包，从而找到了解决方案。 但是我不想通过将sudo附加到它来安装该软件包。

有什么办法吗？

Answer 1

启动python项目时，请始终使用python virtual environemnt 。 避免使用sudo pip install 。

你可以

1. 创建Pycharm虚拟环境 ，或
2. 创建典型的virtualenv，然后将外部virtualenv添加到Pycharm，或者
3. 将pycharm与另一个虚拟环境conda一起使用。

Answer 2

尝试使用sudo如果有需求文件，例如sudo pip install -r requirements.txt或独立软件包

sudo pip install <package-name>
