使用pip3安装Orange3

如何解决使用pip3安装Orange3

我一直试图在我的Linux机器上安装orange3。尝试后：

pip3 install orange3

我收到此详细错误：

WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
Defaulting to user installation because normal site-packages is not writeable

我已经尝试使用来更新pip和设置工具

pip install --upgrade pip

等，但我仍然收到此错误。

解决方法

您的setuptools软件包版本可能太旧。尝试升级它（也可以同时点上它）：python3 -m pip install setuptools pip。
