D:\PortablePython37<python -m pip list
Package Version
---------- -------
pip 10.0.1
setuptools 39.0.1
You are using pip version 10.0.1, however version 18.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
可見預設只安裝了 pip 與 setuptools 這兩個模組而已, 在網路暢通環境下可用 python -m pip install 指令安裝所需要的模組. 但在離線或有防火牆阻擋環境下, 則需要用到 App\Python\Scripts 下的 setup_tools.exe 安裝已下載的模組檔案 (whl 或 gz 檔) :
# 如何在 Portable Python 離線安裝模組
不過由於模組相依問題, 離線安裝通常要準備全部相依的模組才能順利安裝, 作者建議在網路暢通環境下安裝全部用得到的模組較省事. 我常用的模組安裝指令如下, 主要是機器學習與網路爬蟲等相關之模組 :
python -m pip install scipy
python -m pip install pandas
python -m pip install matplotlib
python -m pip install scikit-learn
python -m pip install --upgrade tensorflow
python -m pip install keras
python -m pip install requests
python -m pip install beautifulsoup4
python -m pip install lxml
python -m pip install html5lib
python -m pip install selenium
python -m pip install pymysql
python -m pip install mysqlclient
python -m pip install xlrd
python -m pip install fix_yahoo_finance
python -m pip install openpyxl
python -m pip install "django<1.9"
python -m pip install virtualenv
python -m pip install paramiko
注意 :
如果電腦中原本已安裝了 Python, 則必須到 "系統/進階設定" 中將 path 中的 Python 路徑 (例如 C:\Python36\Scripts\, C:\Python36\) 暫時移除, 否則 pip install 安裝時會安裝到原本的 Python 安裝目錄裡, 而不是 Portable Python 裡, 安裝完再恢復 path 原設定. 另外, Numpy 於安裝 Scipy 時會一併安裝, 不需單獨安裝.

上面的模組除了 mysqlclient 外均順利安裝完成, mysqlclient 則出現如下錯誤訊息 :

有看沒有懂, 這模組就算了, 反正有 PyMySQL 就可以了.
另外, 因 tensorflow 目前僅支援到 Python 3.6, 而此 Portable Python 為 3.7.0 版, 因此用 pip 安裝時會報 "No matching distribution found" 錯誤, 所以就先不安裝, 等以後支援了再說, 連帶 Keras 也是以後再安裝 :
D:\PortablePython37>python -m pip install tensorflow
Collecting tensorflow
Could not find a version that satisfies the requirement tensorflow (from versions: )
No matching distribution found for tensorflow
最後用 pip list 查看已安裝模組如下 :

安裝完後約 350MB, 沒想到這些模組加起來竟然這麼大! 重新壓縮後的 ZIP 檔也膨脹到 150MB 左右, 這樣就可以移到無法線上安裝的電腦使用了.
2018-10-26 補充 :
安裝完所需模組移到網內使用時若仍發現缺了那些模組, 不用回網外電腦安裝後再搬檔案, 只要去 PyPi 網站下載該模組之 whl 檔 (以及所有相依模組) 安裝即可, 例如今天發現 pexpect 好用沒安裝到, 於是下載了 pexpect 及其相依模組 ptyprocess 以 pip 安裝m 例如 :
C:\Python37>python -m pip install ptyprocess-0.6.0-py2.py3-none-any.whl
Processing c:\python37\ptyprocess-0.6.0-py2.py3-none-any.whl
