OSERROR：无法加载库RPY2

Question

我正在运行以下代码：

# This is a setup cell so that Python and R can run in the same Jupyter notebook
# and so that the text of plots is bigger by default.
import altair as alt

# Set a bigger default font size for plots
def bigger_font():
    return {
        'config': {
            'view': {'continuousWidth': 400, 'continuousHeight': 300},
            'legend': {'symbolSize': 14, 'titleFontSize': 14, 'labelFontSize': 14}, 
            'axis': {'titleFontSize': 15, 'labelFontSize': 12},
            'encoding': {'x': {'scale': {'zero': False}}}}}
alt.themes.register('bigger_font', bigger_font)
alt.themes.enable('bigger_font')

# Ensure that altair plots show up in the exported HTML
# Save a vega-lite spec and a PNG blob for each plot in the notebook
alt.renderers.enable('mimetype')
# Handle large data sets without embedding them in the notebook
alt.data_transformers.enable('data_server')

# Load the extension so that we can use the %%R cell magic
%load_ext rpy2.ipython

我会收到以上代码的rpy2扩展部分的以下错误：

我为什么要得到这个，我该如何解决问题？
