Virtualenv - IOError：[Errno 1] 不允许操作：'/bin/easy_install'

Question

运行此命令时：

$ sudo virtualenv ENV --python=python2.7

我收到以下信息：

我安装了python2.7，但也安装了python3，这可能会导致冲突。我完全卸载python3没有成功。

目录和文件/bin/easy_install不存在，有没有办法配置virtualenv指向easy_install所在的正确目录？

我在 macOS 上运行它。非常感谢遇到类似情况的任何人的帮助！

想通了。删除了所有版本的 Python、virtualenv 和 easy_install。并重新安装了除 Python3 之外的所有内容。
