Julia出现错误ERROR: LoadError: syntax: try without catch or finally

因项目要求进行机器学习数据可视化，要求尝试使用Julia，在此，记录下遇到的坑，仅为记录效果。后续陆续更新。

问题一：关于LightML库中的坑：ERROR: LoadError: syntax: try without catch or finally

问题描述：　

ENV["PYTHON"]=""
Pkg.add("Conda")
using Conda
Conda.add("python==2.7.13")
Conda.add("matplotlib")
Conda.add("scikit-learn")
Pkg.add("PyCall")
Pkg.build("PyCall")

Pkg.clone("https://github.com/memoiry/LightML.jl")

当使用using LightML时出现问题：ERROR: LoadError: syntax: try without catch or finally

问题分析：

　　很明显这是由于try...catch../finally的问题

问题解决：

　　定位到文件Gadfly.jl，在980行处加上catch即可，此类问题都可以这样处理。
