Python 安装 setuptools 时报 Compression requires the (missing) zlib（python安装setuptools报错）

装机员为您提供 Python 安装 setuptools 时报 Compression requires the (missing) zlib 的文章咨询供您阅读，如何使用 Python 安装 setuptools 时报 Compression requires the (missing) zlib 的方法对您有帮助也请您举手之劳分享给您身边的人。 

背景：虚拟机 CentOS 下安装 Python 辅助工具 setuptools 报错，错误信息大概如下：

Traceback (most recent call last): 

File "setup.py", line 94, in <module> 

scripts = scripts, 

File "/usr/local/lib/python2.7/distutils/core.py", line 152, in setup

z = zipfile.ZipFile(zip_filename, mode, compression=compression) 

File "/usr/local/lib/python2.7/zipfile.py", line 681, in __init__ 

"Compression requires the (missing) zlib module" 

RuntimeError: Compression requires the (missing) zlib module

出错原因：

提示的很清楚，缺少 zlib 模块导致安装失败

解决方式:

# yum install zlib 

# yum install zlib-devel 

下载成功后，进入 python2.7 的目录，重新执行 

#make 

#make install 

此时先前执行的 软连接仍旧生效 

然后进入 setuptool 目录， 

[root@localhost setuptools-5.2]# pythonnew setup.py install  重新安装

基本这样就可以搞定。

"One or more types required to compile a dynamic expression cannot be found. Are you missing...

#事故现场：

　　在一个.net 4.0 的项目中使用 dynamic，示例代码如下：

1 private static void Main(string[] args)
2 {
3     dynamic obj;
4     obj = new { name = "jack" };
5     Console.WriteLine(obj.name);
6 }

　　在读取 obj.name 时，报错：

One or more types required to compile a dynamic expression cannot be found. Are you missing references to Microsoft.CSharp.dll and System.Core.dll?

#解决方法：

　　在项目中，添加 Microsoft.CSharp.dll 的引用；

Apache Shiro 使用 RequiresPermissions with Spring...

http://yingzhuo.iteye.com/blog/1709002

根据官方文档在启用Shiro 注解（例如，@RequiresRoles，@RequiresPermissions 等等）时，
需要Shiro 的Spring AOP 集成来扫描合适的注解类以及执行必要的安全逻辑。
只需添加这两个bean 定义到applicationContext-shiro.xml 中：

<beandepends-on="lifecycleBeanPostProcessor"/>

<bean>
    <property name="securityManager" ref="securityManager"/>
</bean>

但是，在使用Spring MVC 的情况下，会遇到：
Exception: org.hibernate.HibernateException: No Session found for current thread

解决方法：
将以上代码移至Spring MVC 的servlet 配置文件，如：applicationContext-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"

	xsi:schemaLocation="http://www.springframework.org/schema/beans

    <!-- Scans the classpath of this application for @Components to deploy as beans -->
    <!-- 只应加装表现层Bean，否则可能引起问题 -->
    <!-- 此处只应该加载表现层组件，如果此处还加载dao层或service层的bean会将之前容器加载的替换掉，而且此处不会进行AOP织入，所以会造成AOP失效问题（如事务不起作用） -->
    <context:component-scan base-package="com.binaryoptions.controller">
    	<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    
    <!-- 其他spring-mvc框架配置 -->
	
    <bean id="viewResolver"
                p:view        p:prefix="/views/"
        p:suffix=".jsp" />
		
    <!-- more bean definitions go here -->
    <!-- 为安全检查使用Shiro 的注解（例如，@RequiresRoles，@RequiresPermissions 等等）。 -->
    <!--   
        以下两个bean的配置是为了在Controller层使用元注释控制权限  
        如果使用spring-mvc一定要不要放在webroot的配置文件中  
     -->
    <beandepends-on="lifecycleBeanPostProcessor"/>

    <bean>
        <property name="securityManager" ref="securityManager"/>
    </bean>
	
    <bean>  
        <property name="exceptionMappings">
