node.js - 运行时不支持平台 `npm run flow`

Question

我在 Ubuntu 14.04 上。 Node 版本为 4.5.0。 npm 版本为 2.15.9。

我的 package.json 开发依赖项中有 flow-bin 版本 0.32.0:

$ cat package.json | grep flow-bin
"flow-bin": "^0.32.0",

flow-bin 包在本地可用:

$ npm ls --depth 0 | grep flow
serverside-node-babel-mocha-flow@1.0.0 /home/mperdikeas/test-project
├── babel-plugin-transform-flow-strip-types@6.14.0
├── flow-bin@0.32.0

我的 npm run flow 目标是:

cat package.json |  grep \"flow\"
"flow": "flow; test $? -eq 0 -o $? -eq 2",

当我运行 npm run flow 时，我得到以下跟踪:

$ npm run flow

> serverside-node-babel-mocha-flow@1.0.0 flow /home/mperdikeas/test-project
> flow; test $? -eq 0 -o $? -eq 2

/home/mperdikeas/test-project/node_modules/flow-bin/cli.js:20
  throw new Error('Platform not supported.');
    ^

当我直接从 shell 运行流程(不使用 npm 和 package.json)时，我得到了相同的跟踪:

$ ./node_modules/flow-bin/vendor/flow
/home/mperdikeas/test-project/node_modules/flow-bin/cli.js:20
  throw new Error('Platform not supported.');
    ^

Error: Platform not supported.

此消息的含义是什么，即不支持哪个平台？我该如何解决？

我的其他目标(例如 npm run test 和 npm run start)工作正常。看来这跟Flow有关。

Flow 需要 64 位操作系统。您可能正在运行 32 位版本的 Ubuntu 吗？
