node.js - 无法使用 StrongLoop Arc 连接到 StrongLoop PM

Question

我在使用 StrongLoop Arc 连接到 StongLoop PM 时遇到问题。我正在关注these directions .

这是我尝试过的:

# in one terminal window, I started up StrongLoop PM
$ nvm install v0.12.4
$ nvm alias default 0.12.4
$ npm install -g strongloop
$ slc loopback
> name: hello-strongloop
> directory: hello-strongloop
$ cd hello-strongloop
$ slc pm

# in another new terminal window, I started Arc
$ slc arc # enter login credentials, click process manager, and add pm host
> host: localhost
> port: 8701

按“连接”图标后，我在“应用程序状态”下收到一条消息:

unknown exception: invalid
Unknown "ServiceInstance" id "undefined".

顺便说一下，第二个终端的输出是:

$ slc arc
Loading workspace /home/s/strongloop/hello-strongloop
Embedded Process Manager [(none)]:  starting
StrongLoop Arc is running here: http://localhost:60520/#/

Answer 1

您需要先构建并部署 Loopback 应用程序(使用 Arc)，然后才能使用 Arc 管理流程。通过调用 $ slc arc 从项目目录启动 Arc，然后从 Web 界面单击“构建和部署”。

您还需要从主目录(而不是项目目录)运行 $ slc pm。这将解决您在 Arc 中收到的错误消息的问题。
