pip安裝python三方庫

『壹』 python第三方庫如何安裝

1、在cmd命令行直接使用pip install 包名命令安裝
示例：

注意：安裝成功會顯示Successfully installed keras，如果出現黃色字體警告，是由於pip庫包不是最新的，但keras庫已成功安裝，可隨後對pip包進行更新，更新命令：python -m pip install --upgrade pip。
2、手動下載第三方庫，然後在cmd命令行使用pip install 下載文件名命令安裝下載的第三方庫（https://www.lfd.uci.e/~gohlke/pythonlibs/）

『貳』 python用了第三方庫怎麼在其他地方用

python用了第三方庫在其他地方用的方法是採用pip工具安裝。因為python自帶了包管理器，在使用第三方庫之後在別的地方可以使用pip命令自動安裝，然後就可以在別的地方也使用這些第三方庫了。

『叄』 如何在安裝pip3以及第三方python庫

• 環境

  OS:10.12.3 (16D32) macOS Sierra
  Python3: Python 3.6.1
  

• 1

• 2

• 3

• 什麼是pip

  Python之所以強大，其中一個原因是其豐富的第三方庫。pip則是python第三方庫的包管理工具。
  由於在Mac上python2和python3是共存的。因而python3對應的包管理工具的命令就是:pip3

• 如何安裝pip3

  如果通過homebrew安裝python3，那麼pip3會同時安裝。所以建議直接通過homebrew安裝python3:
  

• 1

• 2

• $brew install python3//no need sudo1


• 如果你已經通過其他渠道安裝了python3但是尚未安裝pip3，那麼需要通過以下步驟實現安裝：12



https://pip.readthedocs.io/en/stable/installing/

• 上述的鏈接是官方給出的方法，但是有幾個地方需要注意，最好按照我博客一步步來：12



https://bootstrap.pypa.io/get-pip.py

• 復制粘貼另存為鏈接中的文本,可以保存為get-pip.py。


• 注意：其中內容很多，必須等網頁載入完再復制，然後通過已經安裝的python3解釋器解釋執行另存為的文件123


• $python3 get-pip.py1



再次執行上述命令，顯示:

• Requirement already up-to-date: pip in /usr/local/lib/python3.6/site-packages1



安裝成功

• 如何安裝第三方庫

  有了pip3以後，安裝第三方庫就容易多了，比如：
  

• 1

• 2

• $pip3 install requests


• Collecting requests


• Downloading requests-2.13.0-py2.py3-none-any.whl (584kB) 100% |████████████████████████████████| 593kB 298kB/s


• Installing collected packages: requests


• Successfully installed requests-2.13.0

『肆』 python 第三方庫怎麼安裝

【方法一】: 通過setuptools來安裝python模塊
首先下載
NOTE: 最好下載個setuptools，本人是15.2版本，裡麵包含了ez_setup
運行 python ez_setup.py
D:\work\installation\setuptools-15.2\setuptools-15.2>python ez_setup.py > 1.txt
Extracting in c:\users\admini~1\appdata\local\temp\tmpbxikxf
Now working in c:\users\admini~1\appdata\local\temp\tmpbxikxf\setuptools-15.2

【方法二】: 通過pip來安裝python模塊
安裝 easy_install pip
D:\work>easy_install pip
Searching for pip

【方法三】:直接從網上下載下可執行文件來安裝.
比如說，去 >>> pythonlibs <<< 網站，提供了很多Python非官方包下載，二進制文件，下載安裝方便.
