TextAnalysis.jl Naive Bayes Load Error

I am trying to use TextAnalysis.jl for some text classification using the Naive Bayes Classifier. However, I’ve been unable to begin as I’m getting an error before I can even load the classifier.

using TextAnalysis: NaiveBayesClassifier, fit!, predict

Produces this error

ERROR: UndefVarError: NaiveBayesClassifier not defined

I know TextAnalysis.jl is installed and it loads on its own ( using TextAnalysis ). How can I fix this?
