用pip安裝chompack失敗

Question

我試圖安裝chompack用pip在支持向量機算法中使用cvxopt。但它給了我一個錯誤，我沒有找到明確的答案。有一個related question但提供的答案是非常具體的人試圖安裝的軟件包。在我的情況下，沒有二進制包，我可以下載，甚至沒有文件。

特定錯誤似乎是

error: command '"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\cl.exe"' failed with exit status 2 

這就是我在命令提示符（Windows 10 PC）和完整的結果類型。

pip install chompack 

我得到

我不知道確切原因，但你應該使用Python本身安裝軟件包爲chompack：

python -m pip install chompack 

如需進一步信息閱讀使用手冊：https://docs.python.org/3/installing/

PS：我看過相同的信息，但它安裝了它無論如何。
