python - 在VS2017中pip安装龙卷风失败

尝试使用以下命令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' -----

我也尝试下载Git zip并使用此命令pip install -Iv https://files.pythonhosted.org/packages/e6/78/6e7b5af12c12bdf38ca9bfe863fcaf53dc10430a312d0324e76c1e5ca426/tornado-5.1.1.tar.gz （如此处引用：Installing specific package versions with pip）

http://www.tornadoweb.org/en/stable/显示

Tornado 5.x在Python 2.7和3.4+上运行

我也尝试了pip install --user tornado，如此处引用的：Tornado Install Issue

所有选项最终都出现相同的最终错误：安装失败。

我猜测它与此有关：(from versions: )，但我对pip / python还是陌生的

按照hoefling的要求尝试pip install -vvv …（输出中还有更多内容

）
