centos7 安装 pyspider 出现的一系列问题及解决方案集合

先安装python3 和 pip3

wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz

安装zlib-devel包(后面安装pip需要用到,这里先下载，后面就不用重复编译)

yum install zlib-devel

tar -xvf Python-3.6.5.tgz

yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

./configure --prefix=/usr/local/python3/ --with-zlib=/usr/include --enable-loadable-sqlite-extensions

make && make install
ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3

pip3 安装

wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb

tar -zxvf pip-8.0.2.tar.gz
cd pip-8.0.2
sudo python3 setup.py build
sudo python3 setup.py install
sudo ln -s /usr/local/python3.4/bin/pip3 /usr/bin/pip3

出现的错误

During handling of the above exception, another exception occurred:

在安装 pyspider 的时候我就遇到了这个问题， pyspider 依赖 pycurl 这个库，而 pycurl 要求系统中存在相对应的库。(如果系统自动安装我们要先卸载)

---------------------------------------------------------------------

pip remove pycurl

`yum install libcurl-devel`

export PYCURL_SSL_LIBRARY=openssl >> ~/.bashrc

source ~/.bashrc

pip3 install pycurl

--------------------------------------------------------------------------

ubuntu的方案

sudo apt-get install libssl-dev libcurl4-openssl-dev python-dev

pip3 install pyspider
