Node Sass does not yet support your current environment解决办法

在启动Nodejs项目时出现以下Error: 

Error: Node Sass does not yet support your current environment: Linux 64-bit with Unsupported runtime (57)
For more information on which environments are supported please see:

error: Forever detected script exited with code: 1

然后先卸载再安装node-sass：

cnpm uninstall --save node-sass

cnpm install --save node-sass

还是出现Error：

✖ Install fail! Error: post install error, please remove node_modules before retry!
Run "sh -c node scripts/install.js" error, exit code 1
Error: post install error, please remove node_modules before retry!
Run "sh -c node scripts/install.js" error, exit code 1

    at maybeClose (internal/child_process.js:925:16)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:209:5)

所以根据上面的提示

please remove node_modules before retry

就删除nodejs项目目录下的node_modules:

rm -rf ./node_modules

重新执行整个cnpm install

cnpm install

结果就可以了。
