Question

尝试遵循我理解的最佳实践，我安装了virtualenv以便能够在本地安装python模块（并且不会破坏任何其他程序或依赖项）。不幸的是，当我尝试打开一个新的虚拟环境时（在bash中，在OSX中），我看到以下错误：

   $ virtualenv venv

我已经搜索了错误，但是似乎没有一种解决方案适用于这种情况。从这里去哪里可能是个好地方？

为了后代，这是我克服此错误的方法：

正如Prashant Rana指出的那样，anaconda正在该系统上使用。解决方案是使用anaconda而不是venv创建虚拟环境。在外壳中，我运行了：

$ conda install -c conda-forge desired_module_name

然后

$ conda create -n mypython3 python=3

最后

$ source activate mypython3

尝试打开虚拟环境时出现错误
