Question

我有两个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,

和

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，但命令“node”，“npm”和“install”，“cwd”如何， “fstream”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'

这意味着在执行fs.lstat('/home/ubuntu/.npm/iconv-lite/0.2.11/package/encodings/table/gbk.js', ...)之类的操作时，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。

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

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

这些约为fstream module。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

这是错误发生时的堆栈跟踪（类似于conosle.log(new Error().stack)的输出）：

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)

Answer 2

阅读NPM日志的一个怪癖：要查看流中的第一个错误。上游错误可能导致文件丢失，从而导致许多错误，例如您上面报告的错误。

尝试转到日志的顶部，然后向下滚动，直到找到初始的第一个错误。
