  • centos7 install python3.7 with problem and how to fix it.

    问题如下:

    configure: error: no acceptable C compiler found in $PATH
    缺少gcc
    zipimport.ZipImportError: can’t decompress data 缺少zlib,zlib
    -devel

    No module named '_ctypes'
    3.7版本需要一个新的包libffi-devel

    yum install libffi-devel -y  

    解决如下:

    yum install gcc zlib zlib-devel -y
    yum install libffi-devel -y  
    有关openssl的修复,python找不到ssl模块
    安装模块
    yum install openssl-devel -y
    去掉注视
    # Socket module helper for socket(2)
    _socket socketmodule.c
    
    # Socket module helper for SSL support; you must comment out the other
    # socket line above, and possibly edit the SSL variable:
    SSL=/usr/local/ssl
    _ssl _ssl.c 
            -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl 
            -L$(SSL)/lib -lssl -lcrypto
    有关zlib的修复
    1  到python安装目录下,运行./configure
    
    2  编辑Modules/Setup文件
    
        vim Modules/Setup
    
        找到下面这句,去掉注释
    
        #zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz
    重新编译python3.7
    ./configure --prefix=/usr/local/python3.7
    make && make install

     建立软连接:

    ln -s /usr/local/python3.7/bin/python3 /usr/bin/python3
    ln -s /usr/local/python3.7/bin/pip3 /usr/bin/pip3

    效果:

     顺便安装了Ipython:

    pip3 install ipython  #这里必须解决上面ssl模块的问题
    ln -s /usr/local/python3.7/bin/ipython /usr/bin/ipython

    因为缺少sqlite数据库模块,还有个报错:

    /usr/local/python3.7/lib/python3.7/site-packages/IPython/core/history.py:226: UserWarning: IPython History requires SQLite, your history will not be saved
      warn("IPython History requires SQLite, your history will not be saved")

    解决方法:

    yum install sqlite-devel -y
    重新编译python3.7
    这些坑相当头疼,所以提早把环境给装好

    Ipython效果:
