在工作中使用npm安装包时,有时候会出现安装失败的情况,此时我们需要分析npm安装日志,查看具体失败信息。但是由于npm安装日志的内容比较冗长,阅读起来非常费时费力,因此需要一个工具来帮助我们更方便地查看npm安装日志。这时,日志视图就出现了。
日志视图是一个npm包,可以将终端中的npm安装日志转换成易读的格式,使我们更方便地了解安装过程和失败原因,从而更快地解决问题。
您可以使用npm来安装日志视图,命令如下:
npm install -g npmlogview
安装完成后,就可以在终端中使用日志视图了。
使用日志视图非常简单,只需要在npm安装包时添加参数“--loglevel verbose”即可生成安装日志,然后在终端中运行以下命令:
npmlogview
此时,日志视图会自动读取当前目录下的npm-debug.log文件,并将其转换成易读的格式,方便我们查看。
日志视图还有其他一些常用命令,包括:
以下是日志视图的示例输出结果:
npm install xx
