win10+x64+vs2015安装nodejieba记录

今天使用npm安装nodejieba，遇到不少问题，在此记录一下。
安装前环境：
win10
x64
node v10.14.2
vs2015+vs2017
python 3.8.0
由于使用npm安装nodejieba必须进行编译，于是有了以下这些问题：
python版本问题
gyp ERR! stack Error: Command failed: C:\Users\fygame\AppData\Local\Programs\Python\Python38\python.EXE -c import sys; print "%s.%s.%s" % sys.version_info[:3];
gyp ERR! stack File "<string>", line 1
gyp ERR! stack import sys; print "%s.%s.%s" % sys.version_info[:3];
gyp ERR! stack ^
gyp ERR! stack SyntaxError: invalid syntax
从以上出错信息可以得知，import sys; print "%s.%s.%s" % sys.version_info[:3];是python2的语法，由于我安装的是python 3.8，所以提示语法错误。
解决方案
安装python2，我安装的是python 2.7。不用担心，python2和python3可以同时兼容安装的。安装后请确保将python2的安装目录添加到环境变量Path中（确保python2的路径在python3之前，这样优先使用python2）。
顺带附一下如何指定python2/3：
C:\Users\fygame>py -2
Python 2.7 (r27:82525, Jul 4 2010, 07:43:08) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()
C:\Users\fygame>py -3
Python 3.8.0 (tags/v3.8.0:fa919fd, Oct 14 2019, 19:37:50) [MSC v.1916 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()
VS程序集问题

关键信息是：error MSB4019: 未找到导入的项目“C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v 4.0\V110\Microsoft.Cpp.Default.props”。
打开相应目录，可以看到我安装的程序集是V140，这也是vs2015对应的程序集。

网上有人说，可以通过命令
npm i nodejieba --msvs_version=2015解决，不过我试了没用。也有人说
npm config set msvs_version=2015，试了也是一样的结果。于是我又试了一下
npm config set msvs_version=2017，又提示：
KeyError:2017
于是，找到下面这篇文章：https://blog.csdn.net/yqq1997/article/details/85231849
解决方案
set VCTargetsPath=C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140
当然，为了后续方便，也可以将VCTargetsPath添加到系统环境变量中。重新安装，成功！
