Is there a way to log the output of npm install command
提问by EricS
I ran npm installon a project and it gives a number of errors and warnings that I want to catch, but the output is too long and being cut off so I can't view the full list in the terminal.
我运行npm install了一个项目，它给出了许多我想捕获的错误和警告，但输出太长并且被切断，因此我无法在终端中查看完整列表。
I tried redirect it to a file but the output is still being written to the terminal and I still get an output file which only list the dependency trees.
我尝试将它重定向到一个文件，但输出仍在写入终端，我仍然得到一个只列出依赖树的输出文件。
I also tried to pipe it to less in linux but it still run through many screens until stopped for continue.
我还尝试在 linux 中将其通过管道传输到 less，但它仍会运行许多屏幕，直到停止继续。
I checked npm doc and it doesn't seem to have log functionality, what I want is to be able to log the exact output in a file, how can I do it?
我检查了 npm doc，它似乎没有日志功能，我想要的是能够在文件中记录确切的输出，我该怎么做？

npm install 2>&1 | tee log.txt
npm install 2>&1 | tee log.txt
The 2>&1routes stderr to stdout, so everything will output in a single stream.
将2>&1stderr 路由到 stdout，因此所有内容都将在单个流中输出。

You may only be interested in the warnings and errors, if so try this:
您可能只对警告和错误感兴趣，如果是这样，请尝试以下操作：
The npm arg is
--silent. Ornpm config set loglevel warnif you want to only print warnings and errors. Or you can pipe it to/dev/null.
npm 参数是
--silent. 或者，npm config set loglevel warn如果您只想打印警告和错误。或者您可以将其通过管道传输到/dev/null.
so you have 2 options:
所以你有两个选择：
npm i --silentnpm config set loglevel warnthennpm i
npm i --silentnpm config set loglevel warn然后npm i
