ModuleNotFoundError: No module named '_bz2' in Google Cloud Workstation

Question

I launched a new Google Cloud Workstation and create a single python file with these contents:

import bz2
import binascii

original_data = 'This is the original text.'
print ('Original     :', len(original_data), original_data)

compressed = bz2.compress(original_data)
print ('Compressed   :', len(compressed), binascii.hexlify(compressed))

decompressed = bz2.decompress(compressed)
print ('Decompressed :', len(decompressed), decompressed)

When I tried to run this code I received this error:

Traceback (most recent call last):
  File "/home/user/01/app.py", line 1, in <module>
    import bz2
  File "/usr/local/lib/python3.10/bz2.py", line 17, in <module>
    from _bz2 import BZ2Compressor, BZ2Decompressor
ModuleNotFoundError: No module named '_bz2'

What am I doing wrong?
