我正在尝试创建一个 Flask 应用程序来推送到 Heroku。当我尝试在文件夹中创建 virtualenv 时，我抛出了这个错误：

photo-crawl › sudo virtualenv venv --distribute
Password:
New python executable in venv/bin/python

似乎由于某种原因virtualenv没有将应该放入的所有内容放入venv/bin文件夹中。现在，只有python和两个别名，python2并且python2.7在那里。

谢谢！

我相信这是由旧版本的 virtualenv 和/或 pip 中的错误引起的。看起来您正在使用 virtualenv 1.8.4 和 pip 1.2.1。您是否可以升级到最新的 virtualenv 和 pip（当前 virtualenv 1.9.1 和 pip 1.3.1）？

如果您有安装权限，应该这样做：

pip install pip --upgrade
pip install virtualenv --upgrade

此时运行相同的命令（即sudo virtualenv venv --distribute）应该会给你你想要的。
