Python 无法运行克隆的Flask/Heroku应用程序

我一直在使用笔记本电脑构建Flask/Heroku应用程序。现在已经切换到笔记本电脑B，我正在尝试让应用程序在本地运行。我已经安装了Heroku并将我的应用程序克隆到B上。每当我尝试运行应用程序python run.py时

我在虚拟环境中看到Flask Mail，所以我不知道如何运行它。我也尝试过安装requirements.txt，但似乎没有什么效果。

通过在激活virtualenv的情况下运行哪个pip，检查该pip来自何处。它应该在virtualenv中，您也可以检查python以获得良好的度量

相反，您的pip正在尝试将东西安装到您的全局python安装中，并且它的权限被拒绝，这是正常的，没有root，这很好，这就是我们使用virtualenv的原因

---

确保您拥有最新的virtualenv>=1.10和pip>=1.5。如果没有，请重新安装它们并重新创建使用旧版本制作的任何VirtualNV。或者你的virtualenv在制作时包含了全球网站包？这通常也不是您想要的。

很抱歉响应太晚。我错过了这个。我运行了哪个pip，它读/usr/local/bin/pip。如何在虚拟环境中将其更改为direct to？通常，为正确的virtualenv运行激活脚本应该可以为您正确设置路径，但是如果没有，virtualenv的bin文件夹中也有一个pip脚本，您可以直接运行该脚本。或者，如果您的python是正确的virtualenv的python，那么可以用python-mpip替换。
