标签： python github installation pip zipline

【解决方案1】：

这对我有用：

# Create environment
conda create -n zipline_env python=3.6 ipykernel

# Activate environment, make sure you can see it in jupyter notebooks
conda activate zipline_env
python -m ipykernel install --user --name=zipline_env

# Install Zipline
conda install -c conda-forge zipline

如果我交换了步骤的顺序，它就不起作用。上述命令完成后，我想要的 conda 安装包就可以正常工作了，比如 jupyter、matplotlib 等。
