Reinstall the system, resulting in the need to reconfigure python. Python version 3.7.9 and cartopy version 0.19.0.post1 are used

Example code:

import numpy as np
import cartopy.crs as ccrs
import matplotlib.pyplot as plt
import matplotlib.ticker as mticker
from cartopy.mpl.ticker import LongitudeFormatter,LatitudeFormatter
dlon,dlat=60,30
xticks=np.arange(0,360.1,dlon)
yticks=np.arange(-90,90.1,dlat)
fig=plt.figure(figsize=(6,5))
ax=fig.add_subplot(1,1,1,projection=ccrs.PlateCarree(central_longitude=120))
ax.coastlines()
gl=ax.gridlines(crs=ccrs.PlateCarree(),draw_labels=False,linewidth=1,linestyle=":",color="k",alpha=0.8)
gl.xlocator=mticker.FixedLocator(xticks)
gl.ylocator=mticker.FixedLocator(yticks)
ax.set_xticks(xticks,crs=ccrs.PlateCarree())
ax.set_yticks(yticks,crs=ccrs.PlateCarree())
ax.xaxis.set_major_formatter(LongitudeFormatter(zero_direction_label=True))
ax.yaxis.set_major_formatter(LatitudeFormatter())
plt.show()

The first time you use this command, you need to download the corresponding coalistline file, but there is a problem with the website in the program and you can’t download it. You need to download the file yourself on the earthnatural official website.

Place the file in C: \ users \ XXXX \. Local \ share \ cartopy \ shapefiles \ natural_ Under the earth \ physical path, if the program still reports an error when running, you need to delete the path (. Local \ share \ cartopy \ shapefiles \ natural_earth \ physical) and run it again. After generating the path of the same path, copy the downloaded physical into physical, run it again, and no error will be reported.
