.npmrc文件似乎已正确读取（npm config ls -l通过命令行和 Maven 构建进行检查）。运行的机器
npm无法直接连接到网络，它只能连接到 Nexus npm 注册表 url。因此，代理属性proxy并https-proxy没有设置。由于对 Nexus 的访问受到限制，我从 Nexus 中生成了一个访问令牌。
Nexus 安全令牌由用户名和密码组成，两者都包含
/通常必须是“url 编码”的字符正如预期的那样，使用此配置，运行时
npm install未检测到代理。Nexus npm 注册表代理似乎设置正确（使用生成的令牌连接后，我可以使用 Web 浏览器访问
json文件和下载文件）tgz如果我设置
registry并http://registry.npmjs.org/注释_auth,email,always-auth,strict-ssl属性以及添加proxy和https-proxy配置，npm install则按预期工作（但我将无法在目标环境中执行此操作）
.npmrc文件内容
; Nexus proxy registry pointing to http://registry.npmjs.org/
registry = https://<host>/nexus/content/repositories/npmjs-registry/
; base64 encoded authentication token
_auth = <see question below>
; required by Nexus
email = <valid email>
; force auth to be used for GET requests
always-auth = true
; we don't want to put certificates in .npmrc
strict-ssl = false
loglevel = silly
问题
我应该如何_auth正确生成属性才能npm install按预期工作？
我试过到目前为止
- base64编码（
<username>:<password>）- 结果是
npm info retry will retry, error on last attempt: Error: socket hang up
- 结果是
- base64Encode(urlencode(
<username>:<password>))- 结果是
npm info retry will retry, error on last attempt: Error: This request requires auth credentials. Run `npm login` and repeat the request.
- 结果是
- base64Encode(urlencode(
<username>)):urlencode(<password>))- 结果是
npm info retry will retry, error on last attempt: Error: socket hang up
- 结果是
