先现在在CENT7上面安装的最新的node版本，我把原来的代码从服务器上下载下来后，在安装模块的时候出现错误。大家帮忙看看

Error: /usr/local/project/Ep/node_modules/bcrypt/build/Release/bcrypt_lib.node: invalid ELF header at Error (native) at Object.Module._extensions…node (module.js:450:18) at Module.load (module.js:356:32) at Function.Module._load (module.js:313:12) at Module.require (module.js:366:17) at require (module.js:385:17) at bindings (/usr/local/project/Ep/node_modules/bcrypt/node_modules/bindings/bindings.js:76:44) at Object.<anonymous> (/usr/local/project/Ep/node_modules/bcrypt/bcrypt.js:3:35) at Module._compile (module.js:425:26) at Object.Module._extensions…js (module.js:432:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:313:12) at Module.require (module.js:366:17) at require (module.js:385:17) at Object.<anonymous> (/usr/local/project/Ep/MyModules/TableStructs.js:6:14) at Module._compile (module.js:425:26)

** 这一个错误是因为我把原来的bcrypt包直接拷贝在项目下面的。如果我直接安装bcrypt，错误如下：** gyp WARN EACCES user “lu” does not have permission to access the dev dir "/root/.node-gyp/5.1.1" gyp WARN EACCES attempting to reinstall using temporary dev dir "/usr/local/project/Ep/node_modules/bcrypt/.node-gyp" gyp WARN install got an error, rolling back install gyp WARN install got an error, rolling back install gyp ERR! configure error gyp ERR! stack Error: socket hang up gyp ERR! stack at TLSSocket.onHangUp (_tls_wrap.js:1089:19) gyp ERR! stack at TLSSocket.g (events.js:260:16) gyp ERR! stack at emitNone (events.js:72:20) gyp ERR! stack at TLSSocket.emit (events.js:166:7) gyp ERR! stack at endReadableNT (_stream_readable.js:905:12) gyp ERR! stack at doNTCallback2 (node.js:452:9) gyp ERR! stack at process._tickCallback (node.js:366:17) gyp ERR!
