[英]Python pip install cvxopt error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\cl.exe' failed with exit status 2
嘗試使用“pip install”安裝 cvxopt。 使用 Window 10、Python 3.6.4（64 位），並且已經安裝了 Microsoft Build Tools 2015 和 Visual Studio 14.0。 我也直接從 PyPI 下載了模塊，但沒有運氣。 需要這個優化教程所以有什么建議嗎？ 這是命令行：

我們需要在 cvxopt 之前安裝 numpy+mkl，請檢查這里並下載 numpy+mkl 包和相應的 cvxopt，然后像下面這樣安裝它們：
打開 CMD 並 cd 到下載文件夾
點安裝“numpy-1.13.1+mkl-cp36-cp36m-win_amd64.whl”
點安裝“cvxopt-1.1.9-cp36-cp36m-win_amd64.whl”
由於一些嚴重的依賴（BLAS、LAPACK、SuiteSparse），cvxopt 很難從源代碼安裝（尤其是在 Windows 上）。 在您的情況下，由於具有一些兼容的 c 編譯器設置的更簡單的依賴關系，它已經失敗了。
閱讀安裝文檔你會看到，二進制文件只提供給 python 2.7 和 python 3.4（在 Windows 上）！
因此，要么使用這些 python 版本之一，然后再做一次，
要么使用
anaconda-distribution並通過 conda-forge 安裝，如上面鏈接中所述。
我強烈推薦anaconda方式！
（編輯：如評論中所述，conda-forge 中沒有 Windows 構建）。
Sara 基於 Gohlke 二進制文件的方法可以工作。 但是一般比較麻煩（和其他庫結合的時候）。
還有官方手冊 windows-install但恕我直言它不值得麻煩（並且仍然僅限於某些 python 版本）。
