在MacOS Moj中安装ucl时出错

Question

我有安装在MacOS Mojave上的问题。 我需要一个ucl图书馆在我的项目。我不懂Python。我需要运行一次就绪代码。 当我尝试时：

MBP-ukasz:psCMS2 lukasz$ sudo pip install ucl

我有个错误：

The directory '/Users/lukasz/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
