Miniconda 是一個(gè)輕量級(jí)的 Anaconda 版本烛卧，它是 Anaconda 的一個(gè)最小安裝，僅包含 Conda 包管理器和 Python 解釋器涝婉。

功能類(lèi)似 pipenv侮攀，方便使用不同版本的 python，學(xué)習(xí)成本也比較低迎卤。

安裝

Miniconda — miniconda documentation

conda on WSL （官方文檔安裝在了用戶(hù)家目錄下 ~/miniconda3, 我安裝在了 /opt/miniconda3 目錄下）

$ sudo mkdir -p /opt/miniconda3
$ cd /opt
$ wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O ./miniconda3/miniconda.sh
