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 PATH3. 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 sudo4. 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 && date5. 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

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！
