python安装途中遇到的问题和解决方法

一、setuptools安装错误：RuntimeError: Compression requires the (missing) zlib module

1. 描述

搞了个腾讯云的服务器，闲在手上没事准备当个测试机用用，写写代码什么的。然后按照之前写的文章安装了python2.7，安装的中途出现了一个错误：

其实错误一眼就能看出是缺少了zlib库，然后使用yum install zlib zlib-devel安装了库之后python setup.py install 发现还是一样报错。

2. 解决方法

装好zlib相关库之后把把python重新安装一遍，进入到源码目录：

 

1 2	yum install zlib zlib-devel make && make install

二、setuptools错误：pkg_resources.DistributionNotFound: The "distribute==0.6.10" distribution was not found and is required by the application    [2017-10-21添加]

1. 描述

安装完setuptools准备使用时报错：

 

1 2 3 4 5 6 7 8 9 10

Traceback (most recent call last):   File "/usr/bin/easy_install", line 5, in <module>     from pkg_resources import load_entry_point   File "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 3142, in <module>   File "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 3126, in _call_aside   File "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 3155, in _initialize_master_working_set   File "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 666, in _build_master   File "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 679, in _build_from_requirements   File "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 867, in resolve pkg_resources.DistributionNotFound: The "distribute==0.6.10" distribution was not found and is required by the application

2. 解决方法

缺少distribute模块，使用pip安装也装不上，需要在官网下载源码安装。

 

1 2 3 4

wget https://pypi.python.org/packages/source/d/distribute/distribute-0.6.10.tar.gz tar -zxvf distribute-0.6.10.tar.gz cd distribute-0.6.10 python setup.py install

三、pip报错：pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.    [2017-10-21添加]

1. 错误描述

使用pip安装shadowsocks的时候报错：

 

1 2 3 4 5

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available. Collecting shadowsocks   Could not fetch URL https://pypi.python.org/simple/shadowsocks/: There was a problem confirming the ssl certificate: Can"t connect to HTTPS URL because the SSL module is not available. - skipping   Could not find a version that satisfies the requirement shadowsocks (from versions: ) No matching distribution found for shadowsocks

2. 解决方法

系统缺少openssl-devel包，使用yum install openssl-devel安装。

然后重新安装python：进入python源码目录，make && make install，解决。
