把python脚本编译成exe
目前有三种方法
centos下安装python MySQLdb
源码安装：
点击这里下载源码
解压前线装一下必要的包
yum install python-devel mysql-devel zlib-devel openssl-devel
解压
tar xf MySQL-python-1.2.3.tar.gz
cd MySQL-python-1.2.3
修改mysite.cfg，指定mysql-config的路径
使用whereis mysql-config找路径
vi mysite.cfg
#找到mysql_config = XXX
改为你的路径
继续安装
python setup.py build
python setup.py install
工具安装：
sudo easy_install mysql-python
sudo pip install mysql-python
出现错误的解决办法
---
```bash
vi ~/.bash_profile
# add
export DYLD_LIBRARY_PATH='/usr/local/mysql/lib';
PATH="$PATH:/usr/local/mysql/bin"
enjoy~
Win下请直接下载编译好的安装包：
php不使用中间变量交换两个变量的值
方法一：
$a = $a^$b;
$b = $b^$a;
$a = $a^$b;
这就是位运算带给我们的奇妙之处！（这种方法只适合于int型和string型，而且位数不能超过8位）
方法二：
list($var1, $var2) = array($var2, $var1);

安装Scarpy踩过的坑
#安装Scarpy踩过的坑
Scrapy是python下一个著名的爬虫，目前最新版为0.24。
这是他的帮助文档->Scrapy 0.24 文档
其中**选择器篇**需要好好研究！
帮助文档里的安装指南写得很宽泛，所以安装出错是在正常不过的事了。(再者说，安装出错确实不是Scrapy的错嘛)
So here is the doc to help you with installing Scrapy.
First of all, before installing, please make sure U have already installed these libs or apps below:
- python version >= 2.7
- python-devel package
- libs:
- xml2-dev
- xslt-dev
- ffi-dev
- openssl-dev
If not, commands below may help:
on Redhat/Centos:
yum install python-devel libxml2-devel libxslt-devel libffi-devel openssl-devel bzip2-devel
on Debian/Ubuntu:
apt-get install python-dev libxml2-dev libxslt1-dev libffi-dev libssl-dev libbz2-dev
If your python version is less than 2.7, this article -> upgrade python may help U in upgrading python.
I have summarized some errors when installing scrapy and hope they can be used as a reference for you.
CompressionError: bz2 module is not available
This usually happens when you have compiled python and use pip install Scrapy command.
The reason is you don't have bzip2 lib installed:
on Redhat/Centos:
yum install bzip2-devel
on Debian/Ubuntu:
apt-get install libbz2-dev
After you have installed the bzip2 package,you have to compile python again to make bzip module work.
Finally,use pip install --upgrade scrapy to finish the installation.
Setup script exited with error: command 'gcc' failed with exit status 1
The cause is u didn't install python-dev
on Redhat/Centos:
yum install python-devel
on Debian/Ubuntu:
apt-get install python-dev
Finally,use pip install scrapy or easy_install scrapy to finish the installation.
error: Not a recognized archive type: /tmp/easy_install-dayrGH/Twisted-14.0.0.tar.bz2
Haha,that's because you already have installed the package!
UserWarning: You do not have the service_identity module installed.
sudo pip install service_identity
That's all for now.Thank u for viewing.
