# 安装 Python
|
|
|
|
|
|
|
|
|
|
|
|
只有 Windows 用户需要注意一点，用安装程序安装时一定要记得勾选 `Add Python to PATH`。
|
|
|
|
|
|
|
|
|
|
|
|
# pip
|
|
|
|
|
|
|
|
|
|
|
|
Python 包管理器 pip 的配置文件在 `$HOME/.config/pip/pip.conf`
|
|
|
|
|
|
|
|
|
|
|
|
执行以下语句，可以为当前用户设置 pypi 安装源：
|
|
|
|
|
|
|
|
|
|
|
|
``` sh
|
|
|
|
|
|
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
执行完毕后，`pip.conf` 中会添加如下设置：
|
|
|
|
|
|
|
|
|
|
|
|
``` conf pip.conf
|
|
|
|
|
|
[global]
|
|
|
|
|
|
index-url = https://mirrors.ustc.edu.cn/pypi/web/simple
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
pip 常用的命令：
|
|
|
|
|
|
|
|
|
|
|
|
``` sh
|
|
|
|
|
|
pip install <package> --user # 为当前用户安装指定的包
|
|
|
|
|
|
pip list --user # 列出为当前用户安装的包
|
|
|
|
|
|
pip show <package> # 显示指定包的详情
|
|
|
|
|
|
pip install <package> --upgrade # 升级指定的包，或可用短参数-U
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
当前用户安装的包保存在 `$HOME/.local/lib/python3.xx/site-packages` 中。
|
|
|
|
|
|
|
|
|
|
|
|
# pipenv
|
|
|
|
|
|
|
|
|
|
|
|
一个 Python 虚拟环境管理器，安装方法 `pip install pipenv --user` 。
|
|
|
|
|
|
|
|
|
|
|
|
添加将以下环境参数，pipenv 就可以在当前路径中创建 Python 虚拟环境了：
|
|
|
|
|
|
|
|
|
|
|
|
``` conf env
|
|
|
|
|
|
PIPENV_VENV_IN_PROJECT=enabled
|
|
|
|
|
|
PIPENV_IGNORE_VIRTUALENVS=1
|
|
|
|
|
|
PIPENV_VERBOSITY=-1
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|

|
|
# vscode
