1、安装依赖包
yum -y groupinstall "Development tools"
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
2、根据自己需求下载不同版本的Python3,我下载的是Python3.6.2
wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz
3、解压压缩包,进入该目录,安装Python3
tar -xvJf Python-3.6.2.tar.xz
4、进行Python3的编译安装(其中=后为安装的路径)
./configure --prefix=/usr/python3
make
make install
5、添加软链到执行目录下/usr/bin
ln -s /usr/python3/bin/python3.6 /usr/bin/python3
ln -s /usr/python3/bin/pip3 /usr/bin/pip3
6、查看python和pip的版本
python3 --version
pip3 --version
1、pip安装
pip3 install scrapy
判断是否有错误比如缺少ssl
使用命令:
sudo yum install -y openssl-devel
进行安装,安装完成后用命令添加到python
./configure --prefix=/usr/python3 --with-ssl
2、出现Successfully表明安装成功
3、添加到.bsahrc文件
9、编译.bsahrc文件及python3、scrapy.出现如下图即成功
source .bashrc
python3
scrapy
