what's reason of Error 'EBUSY' when I try to use "cnpm install"?

In this case, cnpm is chinese edison of "npm",it's just the mirror image of npm. This is my package.json file.

  "devDependencies": {
    "autoprefixer-loader": "^2.0.0",
    "babel": "^6.23.0",
    "babel-core": "^6.23.1",
    "babel-loader": "^6.2.4",
    "babel-plugin-transform-runtime": "^6.12.0",
    "babel-preset-es2015": "^6.9.0",
    "babel-runtime": "^6.11.6",
    "css-loader": "^0.23.1",
    "extract-text-webpack-plugin": "^2.0.0",
    "file-loader": "^0.8.5",
    "html-loader": "^0.3.0",
    "html-webpack-plugin": "^2.28.0",
    "style-loader": "^0.13.1",
    "url-loader": "^0.5.7",
    "vue-hot-reload-api": "^1.3.3",
    "vue-html-loader": "^1.2.3",
    "vue-loader": "^11.0.0",
    "vue-style-loader": "^1.0.0",
    "vue-template-compiler": "^2.2.1",
    "webpack": "^2.2.1",
    "webpack-dev-server": "^2.4.1",
    "webpack-merge": "^3.0.0",
    "eslint": "^3.12.2",
    "eslint-plugin-html": "^1.7.0"
  }

I don't know why the "EBUSY" occurs.when I try "cnpm install", the console says:

× Install fail! Error: EBUSY: resource busy or locked, symlink 'C:\Users\Administrator\WebstormProjects\iview-project\node_mod ules_rx-lite@3.1.2@rx-lite' -> 'C:\Users\Administrator\WebstormProjects\iview-project\node_modules_inquirer@0.12.0@inquirer\ node_modules\rx-lite'

Error: EBUSY: resource busy or locked, symlink 'C:\Users\Administrator\WebstormProjects\iview-project\node_modules_rx-lite@3. 1.2@rx-lite' -> 'C:\Users\Administrator\WebstormProjects\iview-project\node_modules_inquirer@0.12.0@inquirer\node_modules\rx- lite'

I can gurantee this is not the reason of "cnpm",but I don't know why this happens.
