Question

我一直在使用笔记本电脑A来构建Flask / Heroku应用程序。现在已切换到笔记本电脑B，我正试图让应用程序在本地运行。我已经设置了Heroku并将我的应用程序克隆到B.每当我尝试运行应用程序时python run.py ...

(venv)admins-MacBook-Air:lhv-talenttracker surajkapoor$ python run.py
Traceback (most recent call last):

    raise ImportError('No module named %s' % fullname)
ImportError: No module named flask.ext.mail

所以我运行pip install Flask-Mail和...

我在虚拟环境中看到了Flask-Mail，所以我对如何运行它感到困惑。我也尝试过安装我的requirements.txt，但这似乎没什么用。

通过激活virtualenv运行pip来检查which pip的来源。它应该在virtualenv中（您可以检查python以获得良好的衡量标准。）

相反，你的pip正在尝试将内容安装到你的全局python安装中，并且它被拒绝权限（正常情况下，没有root权限 - 这很好，这就是我们使用virtualenv的原因）。

确保您拥有最新的virtualenv（＆gt; = 1.10）和pip（＆gt; = 1.5）。如果你没有，重新安装它们并重新创建你用旧版本制作的任何虚拟版。或者也许你的virtualenv在制作时包含了全球网站套餐？这通常也不是你想要的。
