Question

我无法弄清楚如何在运行Anaconda（conda 4.3.18）python 2.7.10的Mac（Sierra 10.12.4）上安装PIL。 Anaconda的默认python是3.5.2，所以我用pip2安装。

My-MacBook-ProX:dymax thisuser$ sudo pip2 install PIL

我为sudo pip2 install pillow收到相同的错误。我也试过了conda：

My-MacBook-ProX:dymax thisuser$ conda install pillow
Fetching package metadata ...........
Solving package specifications: .

# All requested packages already installed.
# packages in environment at /Users/thisuser/anaconda3:
#
pillow                    4.1.1                    py35_0

在Python3中，我可以导入PIL。 Python2.7我仍然得到No module named PIL。感谢您的帮助。我的pip / pip2配置不正确吗？

Answer 1

尝试提供版本

 pip install pillow==6.1.0(latest)

如果不起作用，请尝试

pip list

如果未列出python的搜索位置

which python

在生成的“ python”的位置（通常在lib / python3.5 / site-packages下）中搜索site-packages文件夹，并检查是否存在PIL（软件包未安装正确的位置）

为anaconda安装PIL python2.7
