使用npm list时，“无效”是什么意思？ [英] What does 'invalid' mean when using npm list?

问题描述

我是nodejs的新手，我刚刚在全球安装了Bower模块。从那时起，npm list命令给出了以下输出，这些输出是我在网络上搜索的，但找不到任何帮助：

I am new to nodejs and i had just installed bower module globally. Ever since then, npm list command gives the following output which I searched for on the web but couldn't find any help :

**npm ERR! invalid: chalk@0.5.1 /usr/local/lib/node_modules/bower/node_modules/chalk  
npm ERR! invalid: ansi-regex@0.2.1 /usr/local/lib/node_modules/bower/node_modules/chalk/node_modules/has-ansi/node_modules/ansi-regex  
npm ERR! invalid: configstore@0.3.1 /usr/local/lib/node_modules/bower/node_modules/update-notifier/node_modules/configstore  
npm ERR! invalid: object-assign@0.3.1 /usr/local/lib/node_modules/bower/node_modules/update-notifier/node_modules/latest-version/node_modules/package-json/node_modules/got/node_modules/object-assign  
npm ERR! invalid: registry-url@0.1.1 /usr/local/lib/node_modules/bower/node_modules/update-notifier/node_modules/latest-version/node_modules/package-json/node_modules/registry-url  
npm ERR! invalid: strip-ansi@0.2.2 /usr/local/lib/node_modules/bower/node_modules/update-notifier/node_modules/string-length/node_modules/strip-ansi  
npm ERR! not ok code 0**

其余输出正常，并列出已安装的模块。谁能解释这是怎么回事？

The rest of the output is normal and lists the installed modules. Can anyone explain what's going on?

推荐答案

我在安装有相同软件包的 dependencies和 devDependencies中遇到此错误。

I was getting this error having the same package installed both in "dependencies" and "devDependencies" with different versions.
