我正在尝试在python中运行图像，这意味着我必须安装枕头（因为PIL显然已过时）。（我正在原子中运行它们，因此，如果这在过程中有所改变，请告诉我）。
我已经安装了xCode和homebrew，并且pip似乎已下载，但是// how to use the funciton on line 94

答案 0 :(得分：0)
您尝试运行以下命令以查看帮助：
$ sudo easy_install pip
$ sudo pip install --upgrade pip
$ sudo pip install pillow
答案 1 :(得分：0)
未安装点。 使用
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
然后
python get-pip.py
安装点子。
您可能必须使用sudo特权运行最后一个命令。您可以将python替换为python3或您要使用的任何python版本。
以下是pip的安装手册：https://pip.pypa.io/en/stable/installing/
安装pip后，应使用sudo pip install pillow（在pip前面没有破折号）。
