python 用 python -m pip install --upgrade pip 更新 pip 后 还是不行该怎么办

C:\Users\coddM>pip install pil Collecting pil Could not find a version that satisfies the requirement pil (from versions: ) No matching distribution found for pil You are using pip version 7.1.2, however version 8.1.2 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command.

C:\Users\coddM>python -m pip install --upgrade pip Requirement already up-to-date: pip in c:\python35\lib\site-packages

PIL 可换 Pillow

[coddmajes]

@lxy 主要是 install pillow 后 然后 from PIL import Image 然后就会显示 No module named 'PIL'

@coddmajes install pillow 了都，为啥还 from PIL

[coddmajes]

@infun 那如果要操作图像 应该怎么办 直接可以用 Image.open 之类的吗，我试了好像不能 麻烦能不能告诉一下， python 主要还是在学过程中

[lxy]

@coddmajes 这就不清楚了，在我电脑上是可以的。要不只能试试卸载 Pillow 再重装了。

@coddmajes
额，没用过这个模块
查了一下，用法如下
>>> from PIL import Image
>>> im = Image.open("lena.ppm")

pip install -U PIL --upgrade

[coddmajes]

@infun 其实我也知道是这么用 但是就是每次先用>>> from PIL import Image 就会提示 No module named 'PIL'， 用 Image.open 之后就会提示 name 'Image' is not defined pip install pil 也不行，好晕


@SlipStupig 这个也试了 依旧是这样
C:\Users\coddM>pip install -U PIL --upgrade

@coddmajes 先卸载掉 pip 用 easy_install 装 PIL ，然后用 easy_install 装一下 pip

@SlipStupig 好的 感谢 我试试
