1.安裝支援管理工具
[[email protected] ~]# yum -y groupinstall "Development tools"
2.支援庫的安裝
[[email protected] ~]# 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 --skip-broken
3.Python3安裝
1）下載python安裝包
[[email protected] ~]# wget https://www.python.org/ftp/python/3.5.5/Python-3.5.5.tgz
2）解壓安裝包並且進入資料夾
[[email protected] ~]# tar -zxvf Python-3.5.5.tgz [[email protected]~]# cd Python-3.5.5/
3）對python進行編譯並進行安裝
[[email protected] ~]# ./configure --prefix=/usr/local/python3 [[email protected] ~]# make && make install
4）為python、pip3建立軟連結
[[email protected] ~]# ln -s /usr/local/python3/bin/python3 /usr/bin/python3 [[email protected] ~]# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
安裝Scrapy
1.使用pip3進行
[[email protected] ~]# pip3 install scrapy
Tips：安裝過程中如果出現下圖情況我們可以這般處理：
直接輸入下方命令並執行
pip install pyopenssl ndg-httpsclient pyasn1
執行完畢繼續執行
[[email protected] ~]# pip3 install scrapy
介面出現下圖時說明安裝成功
成功後需要給Scrapy新增軟連結
[[email protected] ~]# ln -s /usr/local/python3/bin/scrapy /usr/bin/scrapy
驗證Scrapy軟連結
[[email protected] ~]# scrapy -v Scrapy 1.5.0 - no active project
安裝完成！！！！
