在 MacOS 10.10 上安装 NumPy for Python 3.6 时出现错误

Question

我正在尝试使用 Python 3.6 在 MacOS 10.10 上安装 NumPy。我是Python新手。我收到如下所示的错误。我将非常感谢任何克服这个问题的建议。我尝试了以下方法：

第一种方法

$ brew install homebrew/python/numpy

Error: /usr/local/Cellar is not writable. You should change the
ownership and permissions of /usr/local/Cellar back to your
user account:
  sudo chown -R $(whoami) /usr/local/Cellar
==> Tapping homebrew/python
fatal: could not create work tree dir '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-python': Permission denied
Error: Failure while executing: git clone https://github.com/Homebrew/homebrew-python /usr/local/Homebrew/Library/Taps/homebrew/homebrew-python --depth=1

第二种方法

$ pip3 install numpy
