1.安装相应的编译工具
在root用户下(不要用普通用户,麻烦),全部复制粘贴过去,一次性安装即可.
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
yum install -y libffi-devel zlib1g-dev
yum install zlib* -y 2.下载安装包
wget wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tar.xz 3.解压
tar -xvJf Python-3.7.2.tar.xz 4.创建编译安装目录
mkdir /usr/local/python3 5.安装
cd Python-3.7.2 ./configure --prefix=/usr/local/python3 --with-ssl
make && make install gcc版本低于8时会报错
Could not import runpy module请参考 https://code84.com/2340.html
6.创建软链接
ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3 7.验证是否成功
python3 -V pip3 -V 8.报错处理
错误1.
zipimport.ZipImportError: can't decompress data; zlib not available Makefile:1099: recipe for target 'install' failed make: *** [install] Error 1
需要安装依赖
yum -y install zlib1g-dev 错误2.
ModuleNotFoundError: No module named '_ctypes'
需要安装依赖
yum -y install libffi-devel 这两个错误需要的依赖已经添加到一开始的依赖安装上去了

9.安装pipenv
在centos中使用python3.7或以上版本,进行pip install 命令容易报错
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Could not fetch URL https:*******: There was a problem confirming the ssl certificate:
Can't connect to HTTPS URL because the SSL module is not available. - skipping
在./configure过程中，如果没有加上–with-ssl参数时，默认安装的软件涉及到ssl的功能不可用，刚好pip3过程需要ssl模块，而由于没有指定，所以该功能不可用。解决办法是重新对python3.6进行编译安装，用一下过程来实现编译安装:
cd Python-3.7.2 ./configure --with-ssl make && make install 即可正常使用pip安装.
这个也在安装python的时候指定了.

10.修改pip安装源
修改系统pip安装源
在家目录下新建.pip文件夹,进入文件夹新建文件pip.conf之后写入相应镜像网站地址
cd ~ mkdir .pip cd .pip vim pip.conf
#进入后添加以下内容,保存退出.
[global] index-url = https://mirrors.aliyun.com/pypi/simple 修改pipenv安装源
在自己的虚拟环境中找到Pipfile文件,将其中的url = "https://pypi.org/simple"修改为你需要的国内镜像,如https://mirrors.aliyun.com/pypi/simple/[root@localhost myproject]# vim Pipfile [[source]] name = "pypi" url = "https://pypi.org/simple" # 改为url = "https://mirrors.aliyun.com/pypi/simple/" verify_ssl = true [dev-packages] #这里是开发环境专属包,使用pipenv install --dev package来安装专属开发环境的包 [packages] # 全部环境的通用包,安装在这里. [requires] python_version = "3.7"
