venv似乎沒有被Python使用

Question

我在Mac上安裝了Python。 如果我運行python -V它輸出3.7.2

如果我運行以下內容：

virtualenv venv
source venv/bin/activate
python -V

我看到3.7.2 。

如果我試圖運行nose我得到這個錯誤：

$ nosetests -s -v config_test.test_config:TestConfiguration
Failure: ModuleNotFoundError (No module named 'boto3') ... ERROR

我立即關注3.6引用。

如果我然后運行pip install boto3我可以在運行pip list時看到包但是當我再次嘗試運行我的應用程序時，我得到與上面相同的錯誤。

我已經嘗試過pyenv global 3.7.2和pyenv local 3.7.2但是沒有任何區別。

任何人都可以提出問題可能是什么？

nose未安裝在venv中。 在我用pip install nose安裝它后，我不得不停用venv並重新激活它。
