我正在使用virtualenvwrapper创建/管理我的虚拟环境。在我的环境中运行pip freeze时，我惊讶地发现在我的新环境中安装了数十个Python模块和软件包（在我知道virtualenv/wrapper之前安装）。mkvirtualenv - 无站点包仍然可以在新环境中找到并安装全局包
这不是预期的行为;我想拥有一个干净的环境，其中只有我在该环境中安装的软件包可用。
我使用的命令是：
mkvirtualenv --no-site-packages mynewenv
当我在新的环境中运行pip freeze，我得到以下一长串（我期待什么可安装在新的环境中）：

我在做什么错？
你正在运行的virtualenvwrapper和virtualenv版本是什么？ – snakecharmerb
@snakecharmerb：virtualenv --version 15.1.0/virtualenvwrapper == 4.7.2 –
在virtualenv中执行'lssitepackages'是否给出相同的输出？ – snakecharmerb
