1、at process._tickCallback (internal/process/next_tick.js:188:7) npm ERR! message: 'request to https://registry.npm.taobao.org/vue-cli failed, reason: connect ECONNREFUSED 127.0.0.1:1080',
1）报错信息大概如下：

2）原因：npm配置了代理（可以使用" npm config list -l "命令查看npm配置）
1 E:WebStormFilelabSystem>npm config list -l 2 ; cli configs 3 long = true 4 metrics-registry = "https://registry.npm.taobao.org/" 5 scope = "" 6 user-agent = "npm/5.6.0 node/v8.11.3 win32 x64" 7 8 ; userconfig C:Users25392.npmrc 9 cache = "E:\ProgramFiles\nodejs\node_cache" 10 cacheE:ProgramFiles odejs ode_cache = "" 11 home = "https://www.npmjs.org" 12 https-proxy = "http://127.0.0.1:1080/" 13 prefix = "E:\ProgramFiles\nodejs\node_global" 14 prefixE:ProgramFiles odejs ode_cache = "" 15 prefixE:ProgramFiles odejs ode_global = "" 16 proxy = null 17 registry = "https://registry.npm.taobao.org/" 18 19 ; default values 20 access = null 21 allow-same-version = false 22 also = null 23 always-auth = false 24 auth-type = "legacy" 25 bin-links = true 26 browser = null 27 ca = null 28 ; cache = "C:\Users\25392\AppData\Roaming\npm-cache" (overridden) 29 cache-lock-retries = 10 30 cache-lock-stale = 60000 31 cache-lock-wait = 10000 32 cache-max = null 33 cache-min = 10 34 cafile = undefined 35 cert = null 36 cidr = null 37 color = true 38 commit-hooks = true 39 depth = null 40 description = true 41 dev = false 42 dry-run = false 43 editor = "notepad.exe" 44 engine-strict = false 45 fetch-retries = 2 46 fetch-retry-factor = 10 47 fetch-retry-maxtimeout = 60000 48 fetch-retry-mintimeout = 10000 49 force = false 50 git = "git" 51 git-tag-version = true 52 global = false 53 global-style = false 54 globalconfig = "E:\ProgramFiles\nodejs\node_global\etc\npmrc" 55 globalignorefile = "E:\ProgramFiles\nodejs\node_global\etc\npmignore" 56 group = 0 57 ham-it-up = false 58 heading = "npm" 59 ; https-proxy = null (overridden) 60 if-present = false 61 ignore-prepublish = false 62 ignore-scripts = false 63 init-author-email = "" 64 init-author-name = "" 65 init-author-url = "" 66 init-license = "ISC" 67 init-module = "C:\Users\25392\.npm-init.js" 68 init-version = "1.0.0" 69 json = false 70 key = null 71 legacy-bundling = false 72 link = false 73 local-address = undefined 74 loglevel = "notice" 75 logs-max = 10 76 ; long = false (overridden) 77 maxsockets = 50 78 message = "%s" 79 ; metrics-registry = null (overridden) 80 node-options = null 81 node-version = "8.11.3" 82 offline = false 83 onload-script = null 84 only = null 85 optional = true 86 otp = 0 87 package-lock = true 88 package-lock-only = false 89 parseable = false 90 prefer-offline = false 91 prefer-online = false 92 ; prefix = "E:\ProgramFiles\nodejs" (overridden) 93 production = false 94 progress = true 95 proxy = null 96 read-only = false 97 rebuild-bundle = true 98 ; registry = "https://registry.npmjs.org/" (overridden) 99 rollback = true 100 save = true 101 save-bundle = false 102 save-dev = false 103 save-exact = false 104 save-optional = false 105 save-prefix = "^" 106 save-prod = false 107 scope = "" 108 script-shell = null 109 scripts-prepend-node-path = "warn-only" 110 searchexclude = null 111 searchlimit = 20 112 searchopts = "" 113 searchstaleness = 900
3）使用" npm config delete https-proxy "命令删除配置 (https-proxy = "http://127.0.0.1:1080/")就可以正常下载啦
