Question

我正在研究Digital Asset Getting Started with Node.js bindings。

运行

npm install @da/daml-ledger

导致以下错误消息

npm ERR! code E401
npm ERR! 401 Unauthorized: @da/daml-ledger@latest

npm ERR! A complete log of this run can be found in:
npm ERR!     /...../.npm/_logs/2019-02-22T17_48_44_560Z-debug.log

以下是该日志文件的内容：

我按照第1步和第2步中的说明进行操作。我的.npmrc会以我收到的输入响应进行更新

curl -umehul@digitalassetsdk:<API_KEY> https://api.bintray.com/npm/digitalassetsdk/npm/auth/scope/da

我输入了命令

npm config set @da:registry https://api.bintray.com/npm/digitalassetsdk/npm

是什么原因导致错误？

Answer 1

从注释中看来，您错过了设置的步骤，也就是说，按照说明告诉您将curl的响应粘贴到~/.npmrc。

应将响应粘贴到〜/ .npmrc（在Windows％USERPROFILE％/。npmrc中）文件中。

作为替代方案，在Linux和MacOS上，您可以将curl的输出通过管道传递到~/.npmrc，如下所示：

curl -u<USERNAME>:<API_KEY> https://api.bintray.com/npm/digitalassetsdk/npm/auth/scope/da >> ~/.npmrc

使用>>运算符将保留~/.npmrc的当前内容，并将curl的输出附加到文件中（或在文件不存在的情况下创建）。如果您想覆盖当前的~/.npmrc文件，只需使用>运算符即可。

Answer 2

Bintary的“设置我的指令”（在https://docs.daml.com/app-dev/bindings-js/getting-started.html的步骤1.3中引用）说要运行curl命令，然后要运行

npm config set @<SCOPE>:registry https://api.bintray.com/npm/digitalassetsdk/npm

当我跳过npm config步骤时，我没有问题。
