TypeError: '<=' not supported between instances of 'str' and 'datetime.datetime'

While running this Python example from the official documentation:

# Import Meteostat library and dependencies
from datetime import datetime
import matplotlib.pyplot as plt
from meteostat import Point, Daily

# Set time period
start = datetime(2018, 1, 1)
end = datetime(2018, 12, 31)

# Create Point for Vancouver, BC
vancouver = Point(49.2497, -123.1193, 70)

# Get daily data for 2018
data = Daily(vancouver, start, end)
data = data.fetch()

# Plot line chart including average, minimum and maximum temperature
data.plot(y=['tavg', 'tmin', 'tmax'])
plt.show()

I get the following error: TypeError: '<=' not supported between instances of 'str' and 'datetime.datetime'

Note: I have all the dependencies installed as requested in the doc. I didn’t get this error a few days ago, I just got it today, maybe it’s related to the latest version?

I had this problem and rm -rf ~/.meteostat and pip install -U meteostat fixed this issue.

Can you try to re-install Meteostat with:

pip install meteostat==1.1.2 -U

By default, the .meteostat folder is located in your home directory (~).
