我在iMac上運行MacOS 10.11.6（El Capitan）。我建立了一個Python 3.4.7虛擬環境，並且我已經安裝了各種軟件包，包括numpy，pandas，scipy等。但是，我很難安裝pymssql。我知道我需要首先安裝FreeTDS，並且我已經使用fink（它安裝了freetds版本0.91-5）來完成此操作。然而，當我啓動一個虛擬的環境和運行：使用pip安裝pymssql失敗並鏈接到使用Mac上的fink安裝的FreeTDS
pip install pymssql
我收到以下錯誤消息（道歉它的大小）：使用自制安裝freetds的

You can install FreeTDS with Homebrew or MacPorts, or by downloading
and compiling it yourself.
Homebrew (http://brew.sh/)
--------------------------
brew install freetds
MacPorts (http://www.macports.org/)
-----------------------------------
sudo port install freetds
setup.py: Not using bundled FreeTDS
setup.py: include_dirs = ['/sw/include']
setup.py: library_dirs = ['/usr/local/lib', '/sw/lib', '/opt/local/lib']

網上說明介紹但我一直使用fink，不想與兩個系統安裝的代碼產生衝突。
我已經更新了fink和pip，並且安裝了最新的setuptools。
我試着運行：
pip install --global-option=build_ext --global-option="-L/sw/lib" --global-option="-I/sw/include" pymssql
...但沒有運氣。
我也嘗試安裝pymssql的早期版本：
pip install pymssql==2.1.1
同樣，沒有喜悅。
或者是錯誤輸出密鑰開始處的'證書驗證失敗'註釋？
我確定我以前在其他機器上安裝過MSSQL，我不記得有任何問題。我也不記得我做了什麼不同（如果有的話）。
任何人都可以幫助我解決這個問題，請。
