linux安装python3.7分三步

1. 安装python3的依赖2.下载python3的包3.编译与安装python

请参照下面步骤，按顺序来。

1. 安装python3的依赖 sudo apt-get install build-essential checkinstallsudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev 2. 下载python3的包

网页下载

https://www.python.org/ftp/python/

https://www.python.org/downloads/

命令下载：

sudo wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz  # 下载python3.7.4的包

推荐解压后放在 /usr/loacl/python3 的目录下

下面是命令参考：

sudo su # 切到管理员cd /usr/loacl # 进入指定目录mkdir python3 # 创建python3的目录cd python3 # 进入python3的目录wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz # 下载python3.7.4的包tar xzf Python-3.7.4.tgz # 解压包 3. 编译python3.7

进入Python-3.7.4解压的目录

cd Python-3.7.4sudo ./configure --enable-optimizations 或 ./configure --prefix=/usr/local/python3 --with-sslsudo make altinstall 或 make && make install

make altinstall用于防止替换默认的python二进制文件/usr/落后的铃铛/python

4. 检验是否安装成功 python3 -V

看到python版本号对不对，如果为3.7说明安装成功

5. 安装python3.7出现ModuleNotFoundError: No module named ‘_ctypes’解决办法 sudo apt-get updatesudo apt-get upgradesudo apt-get dist-upgradesudo apt-get install build-essential python-dev python-setuptools python-pip python-smbussudo apt-get install build-essential libncursesw5-dev libgdbm-dev libc6-devsudo apt-get install zlib1g-dev libsqlite3-dev tk-devsudo apt-get install libssl-dev opensslsudo apt-get install libffi-dev
