mkvirtualenv --无站点包仍然在新环境中查找和安装全局包。

Question

我使用虚拟包装器来创建/管理我的虚拟环境。在我的环境中运行pip冻结程序时，我惊讶地发现，在我的新环境中安装了几十个Python模块和包(在我还没有了解虚拟化/包装器之前就已经安装了)。

这不是预期的行为；我希望有一个干净的环境，只有我在该环境中安装的包是可用的。

我使用的命令是：

mkvirtualenv --no-site-packages mynewenv

当我在那个新环境中运行pip freeze时，我得到了以下长列表(我期望在新环境中不会安装任何东西)：

我做错了什么？

Answer 1

你激活虚拟主机了吗？这是通过“寻找”活动脚本来完成的：

source <env>/bin/activate

其他问题可能是长路径名称或路径中的空格。pwd在您的虚拟目录中提供了什么？
