二、 环境设置及组件安装（首次运行前需要）

1. 系统环境包含 Anaconda 或 Miniconda（python 3.7 版本）

2. 安装 vnpy 2.1.6或以上版本 \

3. 运行安装相关组件

pip isntall -r requirement.txt
conda install -c plotly plotly-orca
conda install -c plotly python-kaleido

如果执行遇到问题可分别执行如下：

1. 通用组件

   pip install -r requirement.txt
   

2. orca 组件 orca 组件为回测功能中保存回测视图结果的组件，windows系统性需要单独安装，才可保证功能正常使用
   安装步骤如下：

   1. 安装组件包

      conda install -c plotly plotly-orca
      

   2. 下载并安装 orca 应用

   组件下载地址：orca组件

   安装后设置话就环境变了 Path 加入相应路径，默认情况下window10操作系统 orca 组件将被安装在如下路径：

   C:\Users\mmmaaaggg\AppData\Local\Programs\orca

   3. 批量关闭 orca 进程方法

   ps -ef | grep orca | grep -v grep | awk '{print $2}' | xargs kill -9
   

3. MD文件转word文档工具
   到pandoc官网下载对应的软件并安装后即可运行 Scripts\md_2_docx.bat 脚本

三、 常用命令

1. 切换远程仓库地址方法

>git remote
origin
>git remote get-url --all origin
https://github.com/IBATS/vnpy_extra.git
>git remote set-url origin [e-mail]:ibats/vnpy_extra.git
>git push

   4f85956..fe47acc  master -> master

2. 数据库 dump 数据

备份主力合约

"c:\Program Files\MySQL\MySQL Server 8.0\bin\mysqldump.exe" -u mg -p --databases vnpy dbbardata --where="symbol in ('rb9999', 'hc9999', 'i9999') and `interval`='1m'" > dbbardata_dump.sql

备份主力，次主力合约

"c:\Program Files\MySQL\MySQL Server 8.0\bin\mysqldump.exe" -u mg -p vnpy dbbardata --where="(symbol like'%9999' or symbol like'%8888') and `interval`='1m'" > dbbardata_dump.sql

3. 压缩命令

zip -r0q /media/mg/Data/output_20201220.zip output

4. 独立启动交易界面（可以多开）

cd d:
cd d:\ide\vnstudio
python.exe -m vnstation runtrader "{'gateway': {'CTP': True}, 'app': {'CtaStrategy': True, 'PortfolioStrategy': True, 'PortfolioManager': True}, 'path': 'D:\\TradeTools\\vnpy\\jianxin_11859077'}"

cd c:\ide\vnstudio
python.exe -m vnstation runtrader "{'gateway': {'CTP': True}, 'app': {'CtaStrategy': True, 'PortfolioStrategy': True, 'PortfolioManager': True}, 'path': r'C:\TradeTools\vnpy_work_root\simnow'}"

四、 各个版本常见错误

2.0.3版本

1. 错误提示框太长，无法看到错误信息

   python.exe -m vnstation
   

2. 错误提示：

   ValueError: numpy.ufunc size changed, may indicate binary incompatibility. Expected 216 from C header, got 192 from PyObject 解决方法：

   Scripts\pip.exe install numpy==1.16.1 --user
   

3. 穿透式测试通不过，采集不到CPU、硬盘、BIOS信息 修改环境变量 增加目录

   C:\Windows\SysWOW64\wbem
