oracledb、jsonschema等无法全局安装

npm配置：

D:\>npm config list
; cli configs
metrics-registry = "https://registry.npmjs.org/"
scope = ""
user-agent = "npm/6.4.1 node/v10.15.0 win32 x64"

; userconfig C:\Users\zyjia\.npmrc
cache = "D:\\program\\nodejs\\npm_cache"
prefix = "D:\\program\\nodejs\\npm_global"

; builtin config undefined

; node bin location = D:\program\nodejs\node.exe
; cwd = D:\
; HOME = C:\Users\zzz
; "npm config ls -l" to show all defaults.

已安装包

oracledb应该还是存在安装失败的问题。
再重新安装下试试，我上个月正好研究过oracledb，参考看看。
