篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Julia出现错误ERROR: LoadError: syntax: try without catch or finally相关的知识，希望对你有一定的参考价值。
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
[ Info: Precompiling LightML [21c72615-c80e-5f28-8897-21b7f06a9402] ERROR: LoadError: syntax: try without catch or finally Stacktrace: [1] include at .oot.jl:317 [inlined] [2] include_relative(::Module, ::String) at .loading.jl:1038 [3] include(::Module, ::String) at .sysimg.jl:29 [4] top-level scope at none:2 [5] eval at .oot.jl:319 [inlined] [6] eval(::Expr) at .client.jl:389 [7] top-level scope at . one:3 in expression starting at C:Usersadmin.juliapackagesGadflyojGNosrcGadfly.jl:971 ERROR: LoadError: Failed to precompile Gadfly [c91e804a-d5a3-530f-b6f0-dfbca275c004] to C:Usersadmin.juliacompiledv1.0GadflyDvECm.ji.

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。
