非常沮丧*。代码适用于 jupyter 实验室，但不适用于 Visual Studio Code。
我创建了干净的新环境，安装、删除、重新安装 [小时过去了]。我已经按照说明安装（在干净的环境中）[例如，conda install -c pyviz/label/dev holoviews]
这里是我使用的版本
hvplot.version = ‘0.6.0’
holoviews.version =‘1.13.3’
pd.version = ‘1.0.5’
我有以下简单的代码……来自你的一个教程
'''
import hvplot.pandas # noqa
from bokeh.sampledata.iris import flowers
import hvplot
#%%
flowers.hvplot.plot(x=‘sepal_width’, y=‘sepal_length’, width=600, groupby=‘species’, kind=‘scatter’ )
'''
这是我设法在调试器中捕获的
SyntaxError: Unexpected token ‘?’
