首先到Github上下载Pyenv相应的一键安装脚本，
|
1
|
$ curl -L https:
//raw
.githubusercontent.com
/yyuu/pyenv-installer/master/bin/pyenv-installer
|
bash
|
安装完毕，设置环境变量，设置环境变量，可以添加到个人家目录的.bashrc或.bash_profile及系统的全
局的/etc/profile，

# Load pyenv automatically by adding
# the following to ~/.bash_profile:
export
PATH=
"/home/lavenliu/.pyenv/bin:$PATH"
eval
"$(pyenv init -)"
eval
"$(pyenv virtualenv-init -)"
|
设置完毕之后，可以在命令行进行验证，

以上都没有问题。比如，安装一个3.5.2的版本Python，
|
1
|
pyenv
install
3.5.2
|
如果下载速度慢的话，可以事先下载之，放到~/.pyenv/cache目录即可。修改~/.pyenv/plugins/python-build/share/python-build/3.5.2文件，

cat

.5.2
#require_gcc
install_package
"openssl-1.0.2g"
"https://www.openssl.org/source/openssl-1.0.2g.tar.gz#b784b1b3907ce39abf4098702dade6365522a253ad1552e267a9a0e89594aa33"
mac_openssl --
if
has_broken_mac_openssl
install_package
"readline-6.3"
"http://ftpmirror.gnu.org/readline/readline-6.3.tar.gz#56ba6071b9462f980c5a72ab0023893b65ba6debb4eeb475d7a563dc65cafd43"
standard --
if
has_broken_mac_readline
if
has_tar_xz_support;
then
install_package
"Python-3.5.2"
"~/.pyenv/cache/Python-3.5.2.tar.gz"
ldflags_dirs standard verify_py35 ensurepip
else
install_package
"Python-3.5.2"
"~/.pyenv/cache/Python-3.5.2.tar.gz"
ldflags_dirs standard verify_py35 ensurepip
fi
|
由于没有~/.pyenv/cache目录，进行手工创建，
|
1
|
$
mkdir
~/.pyenv
/cache
|
如果使用手工安装，则需要安装一些依赖，
|
1
|
# yum install -y gcc make patch gdbm-devel openssl-devel sqlite-devel zlib-devel bzip2-devel readline-devel
|
需要事先准备好Python-3.5.2.tar.gz的安装包，放到~/.pyenv/cache目录下。然后，在命令行直接使用pyenv install 3.5.2即可，
|
1
|
$ pyenv
install
3.5.2
|
安装完毕，使用version命令进行查看，
|
1
2
|
pyenv version
3.5.2 (
set
by
/home/lavenliu/
.python-version)
|
至此，已经安装完毕。
