leo 的安装

下载leo

-rw-r--r--.  1 root root   7282503 Sep 17  2014 Leo-4.11-final.zip

解压

[root@centosTest download]# unzip Leo-4.11-final.zip 

进入Leo然后看安装需求

[root@centosTest Leo-4.11-final]# more INSTALL.TXT

System requirements
-------------------


Leo requires the `Python`_ and `PyQt_` package.
The `PyEnchant`_ package is optional.

可以看到首先需要安装python和pyqt

如果你对这个有了解的话你会知道需要安装pyqt，你得首先安装好qt及sip

下载安装Pyqt4及sip：

http://www.riverbankcomputing.co.uk/software/pyqt/download

安装QT，
下载地址: http://origin.releases.qt-project.org/qt4/source/qt-everywhere-

如果没有安装qt就安装pyqt的话，会报如下类似错误：

[root@cognoswithdb2 PyQt-x11-gpl-4.11.2]#python configure.py

Error: Make sure you have a working Qtqmake on your PATH or use the -q

argument to explicitly specify a working Qtqmake.

有时候安装了qt还是会好上述错误的话，你可以制定qmake路径，如下

[root@cognoswithdb2 PyQt-x11-gpl-4.11.2]# python configure.py -q /usr/bin/qmake-qt4
Determining the layout of your Qt installation...
Error: Qt has been built as static libraries so either the -g or -k argument
should be used.
[root@cognoswithdb2 PyQt-x11-gpl-4.11.2]# python configure.py -q /usr/bin/qmake-qt4 -g
Determining the layout of your Qt installation...
This is the GPL version of PyQt 4.11.2 (licensed under the GNU General Public
License) for Python 2.7.3 on linux2.Type '2' to view the GPL v2 license.
Type '3' to view the GPL v3 license.
Type 'yes' to accept the terms of the license.
Type 'no' to decline the terms of the license.Do you accept the terms of the license? yes
Found the license file pyqt-gpl.sip.

基础环境搭建

安装python2.7

cd /usr/bin
rm -rf python
ln -s /usr/local/bin/python2.7 python
这样做了之后，可能导致一个问题yum 命令不能用，这时需要修改yum
vi /usr/bin/yum
修改第一行的python路径 #!/usr/bin/python2.6因为centos 是用的python2.6

好吧，言归正传，安装sip

就这样一直往后上都看不到头了，总是找不到原因，

Google找make[1]: *** [siplib.o] Error 1

make: *** [all] Error 2半天也没找到解决方法，什么ldconfig呀等等都不行，看来没找对方法用什么浏览器都没用呀！唉，没办法，把错误重定向到文件然后再看

[root@cognoswithdb2 sip-4.16.3]# yum install python-devel
果然安装成功了

安装qt：

下载

-rw-r--r--.  1 root     root  233635127 Sep 18  2014 qt-everywhere-opensource-src-4.8.3.tar.gz

解压安装

./configura   (约十分钟)

Qt is now configured for building. Just run 'gmake'.
Once everything is built, you must run 'gmake install'.
Qt will be installed into /usr/local/Trolltech/Qt-4.8.3To reconfigure, run 'gmake confclean' and 'configure'.

make  ----意想不到的竟然花了7个小时

make install   -----十分钟左右

安装pyqt4

现在安装leo

cp /usr/lib64/python2.6/lib-dynload/_sqlite3.so /usr/local/lib/python2.7/sqlite3/_sqlite3.so  （目标路径根据报错得出）

重新 python launchLeo.py 

发现报另外的错了，没有pyqt4 模块，这难道还要重新安装一遍pyqt,没办法，反正是死马

重新编译安装sip ，pyqt4（这是python configure.py 的时候，因为python调用的是2.7环境，所以她们也是安装在2.7环境下，我是这样理解的）

好吧，一个小时之后，奇迹发生了

--总结，安装leo，花了将近一周的闲暇时间,平均每天晚上整到近两点（都不好意思说），因为对python的不熟悉，因为QT，PYQT，SIP，python之间的兼容性问题，导致安装期间出现了各种数不清的问题，最后最后关头，差点放弃，骂骂咧咧道，去他粮的，什么文学化编程呀，太难整了！但是还是多试了一遍并且安装成功了，想到成功之前的一刻，太难受了，差点放弃，想到马云的一句话（唉，阿里巴巴刚上市），今天很残酷，明天更残酷，后天很美好，很多人都死在明天晚上，看不到后天的太阳!!觉得特别有道理！无数次的尝试，无数次的失败，可以想见，成功是如何的来时不易，成功不是一蹴而就，在将要成功之时放弃，你可以找很多借口，你会觉得没办法，你会说你已经尽全力了！！！但是你放弃了，前面无数次的努力都是白费的，任何时候都要记得，成功是经过无数次白费的努力坚持下来的！！当你在困难面前放弃了，下次遇到问题，还是一样的结果，最后只会是一事无成！！！当你觉得你坚持不下去了，调整好心态，调整好心情，整理一下失败的经验，重新总结下问题的重点，然后重新面对难题，就当是你第一次碰到她，而在此时，你已经积累了很多宝贵的经验，你已经在一个更高的高度，所以决定最后成败的，不是技术，而是你重新面对问题的勇气！！！还有，在困难面前，你会学到的更多！！（近两点，晚安）
