修复dyld： Library not loaded

# 查看python所在的位置
> which python
输出：
/usr/local/bin/python

# 查看 /usr/local/bin/python 的依赖
> otool -L /usr/local/bin/python
输出：
/usr/local/bin/python:
    /usr/local/Cellar/python3/3.6.3/Frameworks/Python.framework/Versions/3.6/Python (compatibility version 3.6.0, current version 3.6.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.0.0)

可以看出依赖3.6.3已经写死了

# 将 /usr/local/bin/python 的依赖更改为当前版本python的路径
# 更改为当前python3.6.5的路径
