由于Python易学、开源、面向对象、可移植性高、库丰富的特点，近期开始学习Python。百度了解了各款Python IDE后，还是认为Eric比较适合我，所以踏上了安装Eric坎坷之路，从选定工具到安装成功一共花费了8天时间，从Windows到Linux再到Mac，挨个折腾了一遍，Windows的搭建比较简单，下载好相应版本直接运行exe就行了，Linux和Mac下我都是用源码包安装的，所以遇到了不少问题最后，终于在Mac上研究明白了。把搭建的整个过程写下来，和与我一样的小白分享。
PS:Mac与Linux的搭建没什么区别，Linux下的也可参考本文，由于我安装过xcode所以gcc我没有再单独去安装，没有的请根据提示自行安装。
一、准备文件
- Python3.4
- Qt5.5.1
- SIP4.17
- QScintilla2.9.1
- PyQt5.5.1
二、安装过程
1.安装Python3.4
从官网（https://www.python.org/download）下载相应平台的版本安装即可
注意！！
-
如果您是iOS开发者,请不要删除python2.7,因为Xcode使用的2.7的脚本,不支持3以上版本!!!
2.安装Qt5.5.1
从官网（http://qt-project.org/downloads）下载相应平台的版本安装即可，路径设成默认（/Users/*/Qt5.5.1）即可
安装完成需要将Qt5添加到环境变量~/.bash_profile
1 vim ~/.bash_profile
将下面两行添加进去
1 PATH="/Users/*/Qt5.5.1/5.5/clang_64/bin:${PATH}" 2 export PATH
3.安装SIP4.14
下载地址：http://www.riverbankcomputing.com/software/sip/download
1 tar -zxvf sip-4.17.tar.gz 2 cd sip-4.17 3 python3 configure.py 4 make && date # 加&&date是个人习惯，make成功会显示时间 5 sudo make install && date # 一定要加sudo
4.安装QScintilla/Qt4Qt5
下载地址：http://www.riverbankcomputing.com/software/qscintilla/download
QScintilla2 文件中有3个文件夹的内容要分别安装：Qt4Qt5，designer-Qt4Qt5和Python。
Qt4Qt5文件夹要在PyQt之前安装，designer-Qt4Qt5和Python要在PyQt之后安装，顺序一定要注意！！
1 cd ./QScintilla-gpl-2.9.1/Qt4Qt5 2 qmake qscintilla.pro 3 make && date 4 sudo make install && date
5.安装PyQt5.5.1
下载地址：https://www.riverbankcomputing.com/software/pyqt/download5
由于是安装在Python的site-packages里，所以要首先确定包的位置
1 python3 2 Python3.4.4(v3.4.4:737efcadf5a6,Dec192015,20:38:52) 3 [GCC 4.2.1(AppleInc. build 5666)(dot 3)] on darwin 4 Type"help","copyright","credits" or "license"for more information. 5 >>> import site 6 >>> site.getsitepackages() 7 ['/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages','/Library/Frameworks/Python.framework/Versions/3.4/lib/site-python','/Library/Python/3.4/site-packages']
知道了位置开始编译
1 cd PyQt-gpl-5.5.1 2 $python3 configure.py -q /Users/**/Qt5.5.1/5.5/clang_64/bin/qmake -d /Library/Python/3.4/site-packages/ #-q 后面的是qmake的位置，-d 后面是Python包的位置 3 make && date
注意！！
我在执行make的时候出了一个这样的错误
1 /Users/Kallan/Documents/Python开发/PyQt-gpl-5.5.1/sip/QtPositioning/qgeolocation.sip:28:10: fatal error: 2 'qgeolocation.h' file not found 3 #include <qgeolocation.h> 4 ^ 5 1 error generated. 6 make[1]:***[sipQtPositioningcmodule.o]Error1 7 make:***[sub-QtPositioning-make_first-ordered]Error2
解决方法：
在/PyQt-gpl-5.5.1/QtPositioning文件夹下创建一个头文件qgeolocation.h，把下面的内容复制进去

继续！
1 make && date 2 sudo make install && date
6.安装QScintilla/Python
1 cd /QScintilla-gpl-2.9.1/Python 2 python3 configure.py --pyqt=PyQt5-d /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/PyQt5--pyqt-sipdir=/Library/Frameworks/Python.framework/Versions/3.4/share/sip/PyQt5-v /Library/Frameworks/Python.framework/Versions/3.4/share/sip/PyQt5 3 make && date 4 sudo make install && date
如果在Python里import不会报错，即代表安装成功，可继续往下进行
1 python3 2 Python3.4.4(v3.4.4:737efcadf5a6,Dec192015,20:38:52) 3 [GCC 4.2.1(AppleInc. build 5666)(dot 3)] on darwin 4 Type"help","copyright","credits" or "license"for more information. 5 >>> import PyQt5.Qsci 6 >>> exit()
7.安装QScintilla/designer-Qt4Qt5
1 cd /QScintilla-gpl-2.9.1/designer-Qt4Qt5 2 qmake designer.pro 3 make && date 4 sudo make install && date
8.安装Eric6
下载地址：http://sourceforge.net/projects/eric-ide/files/eric6/stable/
下载其中的eric6-6.1.1.tar主文件和eric6-i18n-zh_CN.GB2312-6.1.1.tar中文语言包。
将两个文件提取出来，将中文语音包的eric复制到主文件内合并
1 cd eric6-6.1.1 2 sudo python3 install.py
配置Eric6
1、选择Eric6-> preference -> Editor -> Autocompation。勾选所有选框；
2.Editor -> QScintilla 。勾上左右的两个选框，然后在下面source中，选择from Document and API files；
3.Editor -> APIs。勾选Complie APIs Autocompation，在Language中，选择python3。点面下面的Add from installed APIs按钮,选择住需要的.api文件。最后点击Compile APIs；
4、Interface -> Interface。Language选择中文,重启生效。
大功告成！
三、曾经遇到的问题
1.安装QScintilla designer-Qt4Qt5时报错！
1 root@kallan:/media/kallan/D盘/编程学习/python/QScintilla-gpl-2.9.1/designer-Qt4Qt5# qmake -qt5 designer.pro Project ERROR: Unknown module(s) in QT: designer
原因： Qt没有安装好
2.安装QScintilla Python时报错！
1 python3 configure.py --pyqt=PyQt5-d /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/PyQt5--pyqt-sipdir=/Library/Frameworks/Python.framework/Versions/3.4/share/sip/PyQt5--qsci-sipdir=/Library/Frameworks/Python.framework/Versions/3.4/share/sip/PyQt5 2 Error:Make sure you have a working sip on your PATH or use the --sip argument 3 to explicitly specify a working sip.
原因：没有安装SIP
3.安装QScintilla Python时报错！
1 python3 configure.py --pyqt=PyQt5 2 ConfiguringQScintilla2.9.1... 3 QScintilla2.9.1 is being used. 4 TheQScintilla.sip files will be installed in/usr/share/sip/PyQt5. 5 TheQScintilla module will be installed in 6 /usr/lib/python3/dist-packages/PyQt5. 7 PyQt5.3.1 is being used. 8 Qt5.3.1 is being used. 9 sip 4.16.2 is being used. 10 The sip executable is /usr/bin/sip. 11 TheQScintilla module is being built with 'protected' redefined as 'public'. 12 TheQScintilla API file will be installed in/usr/share/qt5/qsci/api/python. 13 Generating the C++ source for the Qsci module... 14 Error:Unable to create the C++ code.
原因：安装顺序错误——先安装的PyQt5，而后安装的QScintilla Qt4Qt5
4.QScintilla的Python安装完成但是在Python中import时报错！
1 >>> import PyQt5.Qsci 2 Traceback(most recent call last): 3 File"<stdin>", line 1,in<module> 4 ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/PyQt5/Qsci.so,2):Library not loaded:@rpath/QtPrintSupport.framework/Versions/5/QtPrintSupport 5 Referenced from:/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/PyQt5/Qsci.so 6 Reason: image not found
5.安装Eric报错！
1 python3 install.py 2 Checking dependencies 3 PythonVersion:3.4.4 4 FoundPyQt5 5 Sorry, please install QScintilla2 and 6 its PyQt5/PyQt4 wrapper. 7 Error: dlopen(/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/PyQt5/Qsci.so,2):Library not loaded:@rpath/QtPrintSupport.framework/Versions/5/QtPrintSupport 8 Referenced from:/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/PyQt5/Qsci.so 9 Reason: image not found
4和5问题的原因是一样的，QScintilla的Python没有安装成功
