学习CryptoZombies的教程，于是使用npm安装truffle: npm i truffle -g，结果装了老半天报错了：

关键的错误信息是
608 error error: pathspec '4.0' did not match any file(s) known to git
联系上下文，大概是依赖包中有个gulp@4.0，然而这个版本已经被官方从git上移除了。
stackoverflow上有个一样的问题：https://stackoverflow.com/questions/70563516/npm-install-giving-error-pathspec-4-0-did-not-match-any-files-known-to-git
其中有个回答，提到用node11就好了。那咱就试试。我想只在安装truffle时使用node11，平时还是使用node16，于是引入下一个问题，如果管理多个版本的nodejs?
很简单，npm的github上明明白白告诉你了~
nvmnvsnavenvoltanodenvasdf-nodejsnvm-windowsfnmnvs就可以选择要安装的nodejs版本，比nvm方便多啦~说明：nvs不能改变安装目录，会安装到
%LOCALAPPDATA%/nvs下
C:\Users\fygame>nvs
Downloading [###########################################################################################] 100%
Extracting [###########################################################################################] 100%
PATH += %LOCALAPPDATA%\nvs\node\11.15.0\x64
查看node版本
C:\Users\fygame>node -v
v11.15.0
查看已经安装的node
C:\Users\fygame>nvs list
>node/11.15.0/x64
查看某个版本node的安装目录
C:\Users\fygame>nvs which 11.15.0
C:\Users\fygame\AppData\Local\nvs\node\11.15.0\x64\node.exe
呜呜，安装到C盘了，我C盘空间不大够，那把npm全局模块目录改到E盘吧:)
C:\Users\fygame>npm config set prefix E:\npm\prefix
C:\Users\fygame>npm config get prefix
E:\npm\prefix
安装下truffle试试
C:\Users\fygame>npm i truffle -g

前面那个报错没了，但是这个新的报错（看起来似乎是执行一段安装后的脚本报错了）似乎也不影响truffle的使用。
使用下truffle看看
G:\tgit\eth\cryptozombiestrial\oracle\EthPriceOracle>truffle
'truffle' 不是内部或外部命令，也不是可运行的程序
或批处理文件。

Error: Node version not supported. You are currently using version 11.15.0 of Node. Truffle requires Node v12.0.0 or higher.
这...truffle需要node 12.0.0以上... 看来stackoverflow也不一定靠谱。那就装个node v12.22.12吧~安装过程和上面一样。
把node12设为默认
G:\tgit\eth\cryptozombiestrial\oracle\EthPriceOracle>nvs link 12.22.12
%LOCALAPPDATA%\nvs\default -> %LOCALAPPDATA%\nvs\node\12.22.12\x64
重新安装truffle，这次上面那两个报错都没有了！
