使用 Virtualenv 在 mac v10.13.4 上下载 tensorflow [重复]

Question

来自站点 tensorflow 提供“Installing TensorFlow on macOS”，但在运行以下命令后：

$ pip install --upgrade virtualenv

我收到以下消息：

Collecting virtualenv
  Using cached virtualenv-15.2.0-py2.py3-none-any.whl
Installing collected packages: virtualenv
  Found existing installation: virtualenv 15.1.0
    Uninstalling virtualenv-15.1.0:
Exception:

During handling of the above exception, another exception occurred:

我已经从 anaconda 下载了 python 3.6。我只是不太擅长终端或了解路径的任何问题。

提前谢谢你！

您应该在安装命令中添加sudo 前缀。

所以：

sudo pip install --upgrade virtualenv
