A while back, I posted about issues with using yfinance and python's
virtual environments.  I was having problems with getting the venv to
work, even though it seemed fairly straightforward.  I ended up
rewriting the python scrips to avoid using yfinance to get around the
problem.

I decided, however, that I really should get venvs working for the next
time that I write something in python.  So I created a venv and
installed yfinance in it.  As expected, it pulled in a slew of other
packages.  I copied the old version of my program (that requires
yfinance) into the directory containing the venv and tried to run it. 
The results are as follows:

---------- First, it says that it can't find curl_cffi ----------

marc:~/PythonProjects$ source pyquotes-y/.venv/bin/activate
(.venv) marc:~/PythonProjects$ cd pyquotes-y
(.venv) marc:~/PythonProjects/pyquotes-y$ pyquotes-y
Traceback (most recent call last):
  File "/usr/local/bin/pyquotes-y", line 12, in <module>
    import yfinance as yf
  File "/usr/local/lib/python3.13/dist-packages/yfinance/__init__.py",
line 23, in <module>
    from .search import Search
  File "/usr/local/lib/python3.13/dist-packages/yfinance/search.py",
line 26, in <module>
    from .data import YfData
  File "/usr/local/lib/python3.13/dist-packages/yfinance/data.py", line
5, in <module>
    from curl_cffi import requests
ModuleNotFoundError: No module named 'curl_cffi'

---------_ Then, I try to install curl_cffi, but pip says it is already
installed and everything is good -----------

(.venv) marc:~/PythonProjects/pyquotes-y$ pip install curl_cffi
Requirement already satisfied: curl_cffi in
./.venv/lib/python3.13/site-packages (0.11.3)
Requirement already satisfied: cffi>=1.12.0 in
./.venv/lib/python3.13/site-packages (from curl_cffi) (1.17.1)
Requirement already satisfied: certifi>=2024.2.2 in
./.venv/lib/python3.13/site-packages (from curl_cffi) (2025.4.26)
Requirement already satisfied: pycparser in
./.venv/lib/python3.13/site-packages (from cffi>=1.12.0->curl_cffi) (2.22)

---------- And the directory listing shows that curl_cffi is there ---------

What am I doing wrong?  It seems like everything should be working, now,
but it isn't.
