Artifactory:无法在“npmjs”找到npm存储库索引

Question

我用的是Artifactory Pro 4.12.1。我创建了一个名为npmjs-local的本地npm存储库，一个名为npmjs-remote的远程npm存储库，以及一个名为npmjs的虚拟npm存储库，该存储库聚合了前两个repos。

然后，我将npm配置为使用Artifactory作为注册表，使用：

$ npm config set registry http://artifactory.example.org/artifactory/api/npm/npmjs

当我试图使用npm search foo搜索一个包时，我会得到以下错误：

npm WARN Building the local index for the first time, please be patient
npm ERR! registry error parsing json
npm ERR! Darwin 15.6.0
npm ERR! argv "/usr/local/Cellar/node/7.2.0/bin/node" "/usr/local/bin/npm" "search" "foo"

我使用--loglevel verbose运行了相同的搜索，我看到“无效的JSON”来自http://artifactory.example.org/artifactory/api/npm/npmjs/-/all

Cannot find the npm repository index at 'npmjs'

编辑：既可以通过Nginx实现，也可以直接通过Artifactory实现。这是完整的HTTP响应：

$ curl -v http://artifactory.example.org:8081/artifactory/api/npm/npmjs/-/all
*   Trying 10.1.2.3...

是什么导致了这个错误？

Answer 1

如果从未生成虚拟存储库的NPM索引，则可能发生这种情况。

解决这个问题的最佳方法是重新索引存储库，这可以使用REST来完成：

curl -uadmin:password -XPOST http://artifactory.example.org:8081/artifactory/api/npm/npmjs/reindex

REST调用将触发异步索引过程，该过程可以使用Artifactory日志文件进行监视。您应该看到这样的消息：
