用VeighNa Station自带的python环境，如何正常更新和安装第三方库?
我使用VeighNa Station自带的python环境，总是报如下问题，这该如何解决？

请问vnpy有如下方法吗，我在自己的策略里如何得到相应的资金和合约数据（例如一跳多少钱）
------------------------------无限易的说明，拷过来用下------------------
VtPositioData -- 持仓数据类
在 ctaTemplate 文件中为 class VtPositioData
含义：持仓数据类，来源为交易所推送的持仓情况。
注意事项：通过 ctaTemplate 文件中定义的 getInvestorPostion 方法获取指定投资者账号的持仓情况，返回的结果是一个数组其中嵌套字典。如果只需要部分字段，可以通过数组的处理方式进行过虑。
VtAccountData -- 账户数据类
在 ctaTemplate 文件中为 class VtAccountData
含义：账户资金情况，来源为无限易自己实时统计计算的资金情况。
注意事项：通过 ctaTemplate 文件中定义的 get_investor_account 方法获取指定投资者账号的资金相关。相关字段数据与柜台推送的数据可能不一致。（统计方式，推送时间可能存在差异）。
VtContractData -- 合约数据类
在 ctaTemplate 文件中为 class VtContractData
含义：获取指定合约的详细信息。
注意事项：通过 ctaTemplate.py 文件中定义的 get_contract 方法获取指定交易所合约的详细情况。期权相关的包括期权的行权价，期权的类型，标的物合约代码。（后续待增加）。
我安装好vnstudio后，利用安装的代码，按照 https://www.vnpy.com/forum/topic/4876-vn-pyshe-qu-jing-xuan-25-quan-shi-chang-qi-huo-shu-ju-pi-liang-he-zi-dong-geng-xin
方式写了自己的代码准备批量下载RQData数据（已开通会员，并且手动下载成功）
发现在如下代码：
def load_data(req):
data = rqdata_client.query_history(req)
database_manager.save_bar_data(data)
报错：
发生异常: TypeError
'NoneType' object is not subscriptable
File "C:\Users\Administrator\BatUpdateData\UpdateAllData.py", line 25, in load_data
database_manager.save_bar_data(data)
File "C:\Users\Administrator\BatUpdateData\UpdateAllData.py", line 37, in <module>
load_data(req)
关于这个问题，我有三个疑问：
1.首先我自己Debug,想进入rqdata.py打断点去看看，结果断点失效：Breakpoint in file excluded by filters.
Note: may be excluded because of "justMyCode" option (default == true).Try setting "justMyCode": false in the debug configuration (e.g., launch.json).
我想断点进源码，该如何设置?
点击更新数据时，抛出如下异常，请问是什么问题？
