在VS2017中pip安裝龍卷風失敗

Question

嘗試使用此命令pip install tornado在適用於Python 3.6 64位的Win10 VS2017上安裝Tornado，並出現以下錯誤：

----- Installing 'pip install tornado' ----- Requirement already up-to-date: pip in c:\\program files (x86)\\microsoft visual studio\\shared\\python36_64\\lib\\site-packages (18.0) Collecting install Could not find a version that satisfies the requirement install (from versions: ) No matching distribution found for install ----- Failed to install 'pip install tornado' -----

我還嘗試下載Git zip並使用以下命令pip install -Iv https://files.pythonhosted.org/packages/e6/78/6e7b5af12c12bdf38ca9bfe863fcaf53dc10430a312d0324e76c1e5ca426/tornado-5.1.1.tar.gz （在此處稱為安裝 ： pip的特定軟件包版本 ）

Tornado 5.x可在Python 2.7和3.4+上運行

我也嘗試了這里的pip install --user tornado ： Tornado安裝問題

所有選項最終都出現相同的最終錯誤：安裝失敗。

我猜它與此有關：（ (from versions: ) ：）處於錯誤狀態，但我對pip / python相當陌生

pip install -vvv …要求嘗試了pip install -vvv … （輸出中還有更多內容）

Answer 1

我重新RTM，並注意到

除了可以通過pip或setup.py install自動安裝的要求之外，以下可選軟件包也可能有用。

因此，我下載了穩定的zip，解壓縮並運行： "C:\\Program Files (x86)\\Microsoft Visual Studio\\Shared\\Python36_64\\python.exe" setup.py install ，它的工作"C:\\Program Files (x86)\\Microsoft Visual Studio\\Shared\\Python36_64\\python.exe" setup.py install 。

我對pip或python的方式還不很了解，因此不知道為什么這樣做有效，而其他方法卻沒有。
