libWtDtPorter.so 的问题

[linonetwo]

在尝试运行 demo 时这样报错：

(trading_env) % python './datakit_stk/runDT.py'     
Traceback (most recent call last):

我已经 pip install wtpy 安装了 0.9.8， 并 pip install -r ./requirements.txt （ requirements.txt 从 wtpy 仓库复制而来）

我是第一次尝试安装使用，请问这个问题如何解决？

Mac 支持可能有问题，我目前用 docker 启动，这里是我的例子：

# Use an official lightweight Python runtime as a parent image
FROM python:3.8-slim

# Set the working directory to /app
WORKDIR /app

# Copy only the requirements file, to cache the dependencies
COPY requirements.txt /app/
RUN pip install --no-cache-dir -i https://pypi.tuna.tsinghua.edu.cn/simple -r requirements.txt
RUN pip install --no-cache-dir -i https://pypi.tuna.tsinghua.edu.cn/simple wtpy

# Copy the rest of the application code
COPY . /app

# Make port 80 available to the world outside this container
EXPOSE 80

# Define environment variable (example)
ENV NAME World
ENV PYTHONPATH /app

# Set the working directory to /app/cta_fut_bt , so `sys.path.append('../Strategies')` works
WORKDIR /demos/ctp_loader

# Run app.py when the container launches
CMD ["python", "./run.py"]

把它放在 wtpy 仓库里，命令行运行

docker build -t wtpy-app . -f ./DockerFile
docker run -p 4000:80 wtpy-app

群里说可以尝试 mac 分支，是贡献者写的，目前还未合并。不过我是用 docker 了。
