problems installing library (xlsxwriter)

[tenicho at g.clemson.edu]

I've in need of using xlsxwriter. 
when running "pip install xlsxwriter" in my command prompt I get the following:
"Requirement already satisfied: xlsxwriter in c:\programdata\anaconda3\lib\site-packages"

But when running "import xlsxwriter" I get the following:
"Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import xlsxwriter
ImportError: No module named 'xlsxwriter'"

Any idea of what is going on or how to fix this?

Thanks in advance!
