# Python , pip 安裝 ###### tags: `Linux`、`python` ## Python 安裝 -- Linux 在 Linux 安裝 Python ### 1. 先在Linux 進行軟體更新 ``` sudo apt update sudo apt upgrade ``` ### 2. 安裝python 依賴套件 ``` sudo apt install build-essential zlib1g-dev libbz2-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev wget ``` ### 3. 安裝 Python 可以先看需要哪個 Python 版本 [https://www.python.org/ftp/python/](https://) ![](https://i.imgur.com/riL3KGW.png) 選擇好後下載壓縮檔，並且解壓縮 ``` wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tgz tar -zxvf Python-3.8.0.tgz ``` ### 4. 編譯和安裝 ``` cd Python-3.8.0 ./configure --prefix=/usr/local/src/python3 # 配置安装位置 sudo make sudo make install ``` ### 5. 建立軟連結 ``` sudo ln -s /usr/local/src/python3/bin/python3.8 /usr/bin/python3.8 sudo ln -s /usr/local/src/python3/bin/pip3.8 /usr/bin/pip3.8 ``` ### 6. 安裝 pip ``` sudo apt install python3-pip ``` ### 7. 自訂指令別名 在 `.bashrc` 或 `.zshrc` 新增以下這段並儲存 ``` # python alias python=python3 alias pip=pip3 ``` 儲存後執行 ``` source .zshrc ``` ### 8. 完成 ``` $ python Python 3.8.10 (default, Mar 15 2022, 12:22:08) [GCC 9.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> ``` ``` $ pip -V pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8) ```
