mod 运行错误

[FallacyWalker]

我照着文档上mod的例子，写了一个helloworld的例子，但是运行时报错：

• rqalpha version : 2.0.0
• python version : 2.7.12

run -f /DeepLink/LocalRqalpha20/rqalpha/rqalpha/examples/buy_and_hold.py -sc 100000

error:

@FallacyWalker 您更新到最新版(2.0.6)试一下？

[lizhi2013]

好像还不行

[hzliu]

试试 develop 分支

[hzliu]

只是 fix 了 with_backtrace 在 python2.7 上出错的问题

[wh1100717]

@FallacyWalker 2.0.8 已经解决了在Python 2.7下 报错 'RQInvalidArgument' object has no attribute 'with_traceback' 的问题
