我有一些問題讓graphlab工作。每次我想導入graphlab我得到的消息：Graphlab get_dependencies（）SSL證書驗證失敗
ACTION REQUIRED: Dependencies libstdc++-6.dll and libgcc_s_seh-1.dll not found.
1. Ensure user account has write permission to C:\Users\Lorenzpc\Desktop\cousera\anaconda installation\Anaconda2\envs\gl-env\lib\site-packages\graphlab
2. Run graphlab.get_dependencies() to download and install them.
3. Restart Python and import graphlab again.
By running the above function, you agree to the following licenses.
* libstdc++: https://gcc.gnu.org/onlinedocs/libstdc++/manual/license.html
* xz: http://git.tukaani.org/?p=xz.git;a=blob;f=COPYING
這個消息後，我做的事：graphlab.get_dependencies（），並得到以下信息：
Downloading xz.

之前，我已經在這裏搜查，但沒有任何問題是相同的或者建議的解決方案不起作用。我試圖重新安裝conda和graphlab幾次在不同的地方（我想也許它與寫權限有關）與安裝程序手動使用點。我試圖手動提取文件（這裏建議的解決方案：Graphlab Create setup error: graphlab.get_dependencies() results in BadZipFile error）。我還嘗試更改導致dependencies.py中的錯誤的代碼行，以便在我的PC上查找這些文件（來自其他論壇的建議）。但無論我做什麼，我都無法讓它工作。
從我的理解，它看起來像錯誤是由連接失敗或因爲它無法建立SSL連接。但我沒有使用代理並且沒有啓用防火牆。
任何對這個問題的原因/解決方案的建議將不勝感激，我已經傷了我一段時間了。
