如何使用MacPorts运行Webots示例？

Question

当我尝试运行示例/robotbenchmark/squar_path示例时，我首先得到消息：

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of Webots will drop support for Python 2.7.

而Python 3.7版本

python --version
Python 3.7.4

是通过我的Macports环境获得的。

port version
Version: 2.5.4

所以我认为Webots不使用我的macports配置文件中的设置--我怎么能做到这一点呢？我尝试将python路径设置为

/opt/local/bin/python

在一般情况下，但后来我收到了一份投诉：

ImportError: dlopen(/Applications/Webots.app/lib/python37/_controller.so, 2): Library not loaded: /Library/Frameworks/Python.framework/Versions/3.7/Python

我还没有看到指定库路径的选项..。

Answer 1

库路径不被识别，/Library/Frameworks/Python.framework/Versions/3.7/Python不存在，但/opt/local//Library/Frameworks/Python.framework/Versions/3.7/Python路径不存在。

因此，作为/Library/Framework中的一个解决方案，我做了一个

sudo ln -s /opt/local/Library/Frameworks/Python.framework . 

现在机器人开始..。
