樹莓派安裝 twder 套件

今天在樹莓派上嘗試安裝 Python 台銀外匯資料擷取套件 twder, 以前只在 PC 上安裝測試過, 參考 :

# Python Fintech 學習筆記 : 用 twder 模組擷取台銀外匯報價

直接用 pip3 安裝卻出現找不到相依套件 libxml2 與 libxslt 的錯誤 :

pi@raspberrypi:~ $ pip3 install twder

總之就是缺了 libxml2 與 libxslt 這兩個相依模組.

直接用 pip3 安裝 libxml2 結果找不到此套件 :

pi@raspberrypi:~ $ pip3 install libxml2
Collecting libxml2
  Could not find a version that satisfies the requirement libxml2 (from versions: )
No matching distribution found for libxml2 

搜尋 "fatal error: libxml/xmlversion.h: 沒有此一檔案或目錄" 找到下面文章 :

# libxml/xmlversion.h: No such file or directory

# [python]解决编译安装 lxml 时提示：libxml/xmlversion.h:No such file or directory

原來 libxml2 與 libxslt 的安裝指令是 :

sudo apt-get install libxml2-dev libxslt-dev     

pi@raspberrypi:~ $ sudo apt-get install libxml2-dev libxslt-dev   

正在讀取套件清單... 完成

Note, selecting 'libxslt1-dev' instead of 'libxslt-dev'

libxml2-dev is already the newest version (2.9.4+dfsg1-2.2+deb9u2).

下列【新】套件將會被安裝：

  libxslt1-dev

安裝過程跑很久, 會讓人誤以為是當機了, 但只要耐心等待, 最後會顯示成功訊息. 其實還有一個做法是, 乾脆在 PyPi 網站下載原始程式來編譯會比較快  (注意, libxml2 與 libxslt 還是要先安裝, 再編譯 twder 原始碼) :

嗯, 大功告成!

總結以上經驗, 樹莓派安裝 twder 的程序是 :

$ sudo apt-get install libxml2-dev libxslt-dev   (相依套件)
$ pip3 install twder    (比較久)

或安裝好 libxml2 與 libxslt 後編譯 twder 原始碼 :

$ wget  https://files.pythonhosted.org/packages/d9/f6/c8c8683aa1c3599d0168bb9476d94af43f0248c0be86b53e2c796614a120/twder-0.1.4.tar.gz     (下載原始碼)
$ tar -xvf twder-0.1.4.tar.gz           (解壓縮)
$ cd twder-0.1.4                              (切換目錄)
$ sudo python3 setup.py install     (安裝)
