无法在Mac上安装节点TA
我正在尝试在特定目录中安装节点talib，但我不断收到以下错误消息：

有人知道我在做什么错吗？我以某种方式认为它会干扰Python，因此我完全删除了Python，但仍然无法正常工作。我有node.js版本v10.16.3和Python 3.7.4。
谢谢，

回答如下：我在这里遇到同样的问题。我发现它与默认的OS X python有关，因为Python3破坏了向后兼容性（有关更多信息，请参见how to change default python version?），因此python从版本2更改为版本3。
我通过打开OS X终端窗口解决了：
$ which python
/usr/local/bin/python
$ /usr/local/bin/python -V
Python 3.7.1
$ which python2.7
/usr/bin/python2.7
$ rm /usr/local/bin/python
$ ln -s /usr/bin/python2.7 /usr/local/bin/python
这将为python2创建一个符号链接，作为您的默认python解释器，从而恢复兼容性。
现在，我能够毫无问题地安装节点talib。
我希望它也对您有用。
