如何阅读npm ENOENT错误

Question

我有2个ENOENT错误.我知道"ENOENT"的意思是"Error NO ENTrance",但这两个ENOENT究竟缺少什么？这些错误消息是什么意思？我想破译它们以便能够调试问题.

npm ERR! Error: ENOENT, lstat '/home/ubuntu/.npm/iconv-lite/0.2.11/package/encodings/table/gbk.js'
npm ERR! If you need help, you may report this *entire* log,
npm ERR! including the npm and node versions, at:

和

npm ERR! Error: ENOENT, chmod '/home/ubuntu/app_f/node_modules/grunt/lib/grunt/util.js'
npm ERR! If you need help, you may report this *entire* log,

npm http GET https://registry.npmjs.org/graceful-fs

一个似乎在gbk.js上有一个"lstat"问题,另一个在util.js上有一个"chmod"问题,但是命令"node","npm"和"install","cwd","fstream"呢？和Object.oncomplete？

这是writer.js:284.这是writer.js:305.

阅读错误行: Error: ENOENT, lstat '/home/ubuntu/.npm/iconv-lite/0.2.11/package/encodings/table/gbk.js'

这意味着当做某事时fs.lstat('/home/ubuntu/.npm/iconv-lite/0.2.11/package/encodings/table/gbk.js', ...),npm收到ENOENT错误.这意味着该文件丢失了,但是npm预计它会在那里.

而对于第二个,npm正在做类似的事情fs.chmod('/home/ubuntu/app_f/node_modules/grunt/lib/grunt/util.js', ...)并且npm收到了ENOENT错误.

其余的是调试信息.这些都是错误发生时的一些变量/属性:

npm ERR! System Linux 3.2.0-54-virtual --> THis is the system type
npm ERR! command "/home/ubuntu/local/bin/node" "/home/ubuntu/local/bin/npm" "install" --> the command that was issued
npm ERR! cwd /home/ubuntu/app_f --> The current working directory
npm ERR! node -v v0.10.26 --> You should know this one!
npm ERR! npm -v 1.4.3 --> You should know this one!
npm ERR! path /home/ubuntu/app_f/node_modules/grunt/lib/grunt/util.js

这些是关于fstream模块.它表明它究竟在做什么.

npm ERR! fstream_path /home/ubuntu/app_f/node_modules/grunt/lib/grunt/util.js
npm ERR! fstream_type File
npm ERR! fstream_class FileWriter
npm ERR! fstream_finish_call chmod

conosle.log(new Error().stack)发生错误时,这是堆栈跟踪(类似输出):

npm ERR! fstream_stack /home/ubuntu/local/lib/node_modules/npm/node_modules/fstream/lib/writer.js:305:19
npm ERR! fstream_stack Object.oncomplete (fs.js:107:15)
