问题描述
尝试使用此命令pip install tornado在适用于Python 3.6 64位的Win10 VS2017上安装Tornado，并出现以下错误：
----- 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' -----
我还尝试下载Git zip并使用以下命令pip install -Iv https://files.pythonhosted.org/packages/e6/78/6e7b5af12c12bdf38ca9bfe863fcaf53dc10430a312d0324e76c1e5ca426/tornado-5.1.1.tar.gz （在此处称为 ： ）
节目
Tornado 5.x可在Python 2.7和3.4+上运行
我也尝试了这里的pip install --user tornado ：
所有选项最终都出现相同的最终错误：安装失败。
我猜它与此有关：（ (from versions: ) ：）处于错误状态，但我对pip / python相当陌生
pip install -vvv …要求尝试了pip install -vvv … （输出中还有更多内容）

1楼
我重新RTM，并注意到
除了可以通过pip或setup.py install自动安装的要求之外，以下可选软件包也可能有用。
因此，我下载了稳定的zip，解压缩并运行： "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 。
我对pip或python的方式还不很了解，因此不知道为什么这样做有效，而其他方法却没有。
