问题 Folks, I have installed the msodbcsql package at least several dozen times. Never had this issue come up. Even spent the entire day yesterday trying to fix this.

Fails with: SQLSTATE[01000] SQLDriverConnect: 0 [unixODBC][Driver Manager

问题 The below lines of code show up every time I open my terminal. Traceback (most recent call last): File "<stdin>", line 3, in <module> ImportError: No module named conda I am worried I have possibly corrupted my (base) conda environment but I haven't run into any issues so far.
