这篇文章主要介绍了在MacOS下安装Python的Pillow库的教程,Pillow库用来对图片进行各种处理操作,需要的朋友可以参考下
今天帮朋友做个python的小工具,发现系统上缺少ptyhon的支持库,返回如下信息
ImportError: No module named PIL
然后就下载安装,因为机器上也没有python的管理工具pip,所以也一并安装
1. 安装pip
- sudo easy_install pip
pip 安装成功就可以直接安装pil或者pillow
2. 通过命令pip install pil
- pip install Pil
- Downloading/unpacking Pil
- Could not find any downloads that satisfy the requirement Pil
- Some externally hosted files were ignored (use --allow-external Pil to allow).
- Cleaning up...
- No distributions at all found for Pil
- Storing debug log for failure in /Users/macbook/Library/Logs/pip.log
3. 所以就安装pillow
- pip install --use-wheel Pillow
- Downloading/unpacking Pillow
- Downloading Pillow-2.4.0.zip (6.5MB): 5.0MB downloaded
- Cleaning up...
弄了会别的回来发现还没有下载完,这叫一个慢呀,于是放弃
4. Git
通过git下载源码地址https://github.com/python-imaging/Pillow
- git clone https://github.com/python-imaging/Pillow.git
然后开始编译安装
4.1
- python setup.py build_ext -i
编译完之后会提示运行测试例子,并且发现JPEG support not available
- --------------------------------------------------------------------
- version Pillow 2.4.0
- platform darwin 2.7.5 (default, Aug 25 2013, 00:04:04)
- [GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)]
- --------------------------------------------------------------------
- --- TKINTER support available
- *** JPEG support not available
- *** OPENJPEG (JPEG2000) support not available
- --- ZLIB (PNG/ZIP) support available
- *** LIBTIFF support not available
- --- FREETYPE2 support available
- *** LITTLECMS2 support not available
- *** WEBP support not available
- *** WEBPMUX support not available
- --------------------------------------------------------------------
- To add a missing option, make sure you have the required
- library, and set the corresponding ROOT variable in the
- setup.py script.
- To check the build, run the selftest.py script.
4.2 因为JPEG support not available,运行python selftest.py报告错误
1 tests of 57 failed.
于是只好卸载pillow
可以通过pip命令来卸载
- pip uninstall pillow
- sudo pip uninstall pillow
- Password:
- Uninstalling Pillow:
- /Library/Python/2.7/site-packages/Pillow-2.4.0-py2.7-macosx-10.9-intel.egg
- /usr/local/bin/pilconvert.py
- /usr/local/bin/pildriver.py
- /usr/local/bin/pilfile.py
- /usr/local/bin/pilfont.py
- /usr/local/bin/pilprint.py
- Proceed (y/n)? y<br> Successfully uninstalled Pillow <br>
成功之后需要安装libjpeg的支持
- brew install libjpeg
安装成功之后重新编译pillow
