場景描述:html
開始以前,先對Debian和Ubuntu操做系統作個瞭解,二者都是Linux陣營中頗有影響力的發行版本,能夠簡單理解成「Ubuntu源自Debian,二者系統操做命令基本相同,相比Ubuntu,Debian更加穩定。」python
關於Debian和Ubuntu的詳細異同能夠點擊此處。linux
ubuntu和debian的版本對應關係:參考git

回到咱們主題,安裝python環境下操做SqlServer的包pymssql;「pymssql官方文檔」sql
聯網環境的話,若是已安裝pip,直接執行pip install pymssql就能夠!一條命令搞定。數據庫
若是離線環境安裝的話,就有點複雜了:ubuntu
首先確認咱們的系統版本:服務器
root@9deba54adab7:/# cat /etc/debian_version 8.11 root@9deba54adab7:/# uname -a Linux 9deba54adab7 4.4.0-105-generic #128-Ubuntu SMP Thu Dec 14 12:42:11 UTC 2017 x86_64 GNU/Linux root@9deba54adab7:/# more /etc/issue Debian GNU/Linux 8 \n \l
大概內心有個印象,當前咱們系統版本爲Debian 8,大致對應ubuntu的14.04。網絡
接下來,咱們先按照正常的安裝步驟走一遍:python2.7
(1) 首先下載pymssql離線安裝源碼包--注意包版本號,以及支持的python版本:https://pypi.org/project/pymssql/2.1.4/
幫人幫到底:點擊 Dowload files
下載並上傳到服務器本地以後,解壓pymssql-2.1.4.tar.gz,而後進入解壓後的目錄,執行:
python setup.py build
python setup.py install
(上邊兩條命令,執行的前提是系統已安裝了setuptools包:https://pypi.org/project/setuptools/#downloads)
執行python setup.py build的時候出現以下異常: Traceback (most recent call last): File "setup.py", line 88, in <module> from Cython.Distutils import build_ext as _build_ext File "/mnt/tt_package/pymssql-2.1.4/Cython-0.29.13-py2.7-linux-x86_64.egg/Cython/Distutils/__init__.py", line 1, in <module> from Cython.Distutils.build_ext import build_ext File "/mnt/tt_package/pymssql-2.1.4/Cython-0.29.13-py2.7-linux-x86_64.egg/Cython/Distutils/build_ext.py", line 5, in <module> from setuptools.command.build_ext import build_ext as _build_ext File "/usr/lib/python2.7/dist-packages/setuptools/command/build_ext.py", line 50, in <module> class build_ext(_build_ext): TypeError: Error when calling the metaclass bases str() takes at most 1 argument (3 given)
基於上述異常,網絡查找資料,WTF,資料少的可憐,難道跟Linux下用某軟sqlserver的用戶少有關麼?!找了半天,無果!
中途嘗試了其餘安裝python包的方式,如:dpkg的方式安裝.deb包,https://pkgs.org/download/pymssql
將上述包,下載下來後執行安裝:
dpkg -i python-pymssql_1.0.2+dfsg-1+b3_amd64.deb
結果~ 結果~!報了一堆依賴問題,擦汗!來來來,順便提供個下載debian依賴包的地址:https://packages.debian.org/buster/libsybdb5
學了一遍,ubuntu下如何蒐集依賴及解決依賴問題:

最後,最後仍是無果!
***********************************************************************************
分割線以後,休息一下,中午吃個飯,一直尋思到底啥問題,甚至有了放棄的念頭,實在不行,寫個Django接口服務,也是一種思路提供參考!
即:在能夠聯網的機器上用Docker裝好pymssql環境,用Django起個服務,跟當前須要訪問sqlserver的程序部署在同一臺服務器上,經過調用接口來實現間接訪問sqlserver數據庫。
PS:這塊功能已實現,回頭梳理下整理出來。
***********************************************************************************
仍是不甘心,怎麼辦?怎麼辦?難道咱們安裝的版本出了問題麼?
更換版本試下;pymssql-2.1.1.tar.gz
按照第一次的安裝步驟,上傳解壓,執行python setup.py install;出現異常:

出現了新的錯誤,網上根據錯誤關鍵字查找,
找到以下靠譜參考:

裏邊基本上都提到了,系統缺乏包:freetds,會致使安裝pymssql的時候,出現異常:error: command 'gcc' failed with exit status 1
OK!
咱們接着繼續安裝缺乏的包:freetds,上邊幾篇參考博客中基本附了下載地址:http://mirrors.ibiblio.org/freetds/stable/
也能夠點擊這裏下載 提取碼: fpmw
下載到本地後,上傳到目標服務器,而後解壓tgz包安裝:
# 解壓 tar zxvf freetds-stable.tgz cd freetds-0.91 # 編譯安裝 ---耐心等待執行完成 ./configure --prefix=/usr/local/freetds --with-tdsver=8.0 --enable-msdblib --enable-dbmfix --with-gnu-ld --enable-shared --enable-static make && make install # 配置freetds: echo "/usr/local/freetds/lib" >> /etc/ld.so.conf.d/freetds.conf # 而後運行如下指令使配置生效 ldconfig -v
到此沒有出現異常的話,基本上freetds包已安裝完成!
接下來重頭戲,從新執行安裝:pymssql-2.1.1.tar.gz,到相應目錄下執行: python setup.py install ---耐心等待

按耐不住心裏的小激動,OK,驗證下是否安裝成功:pip list 查看安裝狀況

不容易~ 一波三折~ 搞定啦!!!
