  • MAC 下安装PIL

    1. 安装使用

    pip install pil

    结果报如下错误

    Collecting PIL
      Could not find a version that satisfies the requirement PIL (from versions: )
      Some externally hosted files were ignored as access to them may be unreliable (use --allow-external PIL to allow).
    No matching distribution found for PIL

    2. 

    This is due to changes in the new version of Pip. Run pip --version and I'm willing to bet you are running 1.5. See the changelog here. This new default behavior enhances security. In PIL's case, the file you are installing actually comes from effbot.org (thus --allow-external) and PyPi doesn't have a checksum to guarantee validity (thus --allow-unverified).

    Also, you might consider using the Pillow replacement to PIL.

    pip install PIL --allow-external PIL --allow-unverified PIL

    报如下错误 :

     /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/tk.h:78:11: fatal error: 'X11/Xlib.h' file not found
      #       include <X11/Xlib.h>
                      ^
      1 error generated.
      error: command 'cc' failed with exit status 1

    3. 

    sudo ln -s  /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.pl
    atform/Developer/SDKs/MacOSX10.10.sdk/System/Library/Frameworks/Tk.framework/Versions/8.5/Headers/X11 /
    usr/local/include/X11

    再次执行:

    pip install PIL --allow-external PIL --allow-unverified PIL

    又报错误 :

        with open(dst, 'wb') as fdst:

    这次是忘了加sudo,加上就OK了。

    localhost:newlabel zhangxin$ sudo pip install PIL --allow-external PIL --allow-unverified PIL

    4. 在使用ImageFont.truetype(fontname, 36)时又出现错误:

    Traceback (most recent call last):
      File "generate.py", line 40, in <module>
        font = ImageFont.truetype(fontname, 36)
      File "/Library/Python/2.7/site-packages/PIL/ImageFont.py", line 218, in truetype
        return FreeTypeFont(filename, size, index, encoding)
      File "/Library/Python/2.7/site-packages/PIL/ImageFont.py", line 134, in __init__
        self.font = core.getfont(file, size, index, encoding)
      File "/Library/Python/2.7/site-packages/PIL/ImageFont.py", line 34, in __getattr__
        raise ImportError("The _imagingft C module is not installed")
    ImportError: The _imagingft C module is not installed
    View Code

    5. 后来,我改变主意了,我卸载了pil,我安装pillow。

    sudo pip install pillow

    然后成功了。叫我神经病吧
