我正在尝试在 Ubuntu 中使用 virtualenv 来安装本地虚拟 Python 环境。当我运行 shell 命令时:
$ virtualenv ./virt_python
它抛出一个它不能 import 的异常pkg_resources
。但是当我打开一个 Python shell 并且from pkg_resources import load_entry_point
它运行良好时。作为参考,完整的堆栈跟踪如下。
$ virtualenv ./virt_python
New python executable in ./virt_python/bin/python
Installing setuptools............done.
Installing pip.......
