我通过brew安装了python3，我安装了virtualenv和virtualenvwrapper，并设置了虚拟环境。我使用pip3.5 install scrapy激活了一个虚拟环境并安装了scrapy（稍后我也使用了pip和pip3 - 我认为我已经开始使用3个不同的版本，但它就是它的本质）
我的〜/ .bash_profile有：
VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3.5
export VIRTUALENVWRAPPER_PYTHON
PYTHONPATH="/usr/local/bin/python3.5:$PYTHONPATH"
export PYTHONPATH
export WORKON_HOME=~/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh
然而，当我运行scrapy startproject tutorial时，我得到了一堆错误，顺便说一句。如果我在激活虚拟环境时运行命令没有区别。我甚至试图在命令中手动设置scrapy的路径 - 仍然没有运气。

有人知道如何解决这个问题或让它发挥作用吗？
