用于数字资产分类账项目的Node.js绑定

我正在努力完成

运行

npm install @da/daml-ledger

我按照步骤1和步骤2中的说明进行操作。my.npmrc会根据输入的响应进行更新

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

---

导致错误的原因是什么？

从注释中可以看出，您错过了设置的一个步骤，即按照说明将

curl

的响应粘贴到

~/.npmrc

响应应粘贴到~/.npmrc（在Windows%USERPROFILE%/.npmrc中）文件中

另一种选择是，在Linux和MacOS上，您可以通过管道将

curl

的输出传输到

~/.npmrc

，如下所示：

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

---

使用

>

操作符将保留

~/.npmrc

的当前内容，并将

curl

的输出附加到文件中（如果文件不存在，则创建它）。如果要覆盖当前的

~/.npmrc

文件，只需使用

操作符即可。

二进制“设置我”说明（在的步骤1.3中引用）说运行

curl

命令并运行

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

npm配置集@：注册表https://api.bintray.com/npm/digitalassetsdk/npm

当我跳过npm配置步骤时，我没有问题。

Hi Meyer。不幸的是，Bintray最近似乎出现了一些问题，您介意再试几次看看它是否成功吗？再试一次，它仍然存在相同的问题。当我运行“npm init”时，是否需要输入什么？当我去更新我的.npmrc时，我注意到它不存在。所以我自己创造了它。也许这会给你一个问题的线索？？？@MeyerAuslander在创建和更新

.npmrc

之后，它现在对你有用吗？下面是我的

.npmrc

，它适用于乒乓球示例@da:registry=//api.bintray.com/npm/digitalassetsdk/npm/：\u authToken=[在此处插入\u您的\u令牌]//api.bintray.com/npm/digitalassetsdk/npm/：username=daniel。sun@digitalassetsdk//api.bintray.com/npm/digitalassetsdk/npm/：email=null//api.bintray.com/npm/digitalassetsdk/npm/：always auth=true``但是现在我在检索包标识符（）时遇到问题。可能是因为我跳过了

config

命令？我的模板ids.json看起来不正确。以下是内容：{“Car.Car”：{“packageId”：“9158c3e66ac2a78e427307b098f7a45e86ddcb40a9be6a26eea0d363e7b48a10”，“name”：“Car.Car”}它应该有一个“Ping”和“Pong”的条目，而不是“Car”

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