window 安装 pyenv
- 下载工具： github.com/pyenv-win/p…
- 将整个包下载下来， 也就是clone->Download ZIP
-
下载完成后将文件夹放在到一个没有中文没有空格的路径当中
-
解压文件得到 pyenv-win-master 文件夹, 这里我放到D盘， 路径也就是 D:\ pyenv-win-master
-
打开cmd， 将路径指到D盘, 看如下
D： E:> rename pyenv-win-master .pyenv # 重命名文件夹，因为直接重命为.pyenv不可以，所以用cmd操作
- 配置环境变量，打开环境变量在系统变量下新建
- 在系统变量中找到 Path, 并添加 %PYENV%\bin 与 **%PYENV%\shims
- 打开cmd ，输入pyenv ，并输出如下， 就代表安装成功了

widnow 国内无法下载或下载包过慢，使用国内镜像
-
当输入pyenv install 3.8.0 无法下载时可按如下操作
- 用vscode打开.pyenv/pyenv-win 搜索 www.python.org/ftp/python 并全部替换成 npm.taobao.org/mirrors/pyt…
pyenv\pyenv-win.versions_cache.xml pyenv-win\libexec\libs\pyenv-install-lib.vbs

pip安装包过慢
- 新建pip.ini 内容如下
[global]
trusted-host=mirrors.aliyun.com
index-url=http://mirrors.aliyun.com/pypi/simple/
2. 在 User/英文用户名 新建一个pip文件夹，并将pip.ini文放进去
- 至此可以使用pip安装包了
