'lightercollective' 不是内部或外部命令，也不是可运行的程序或批处理文件

Question

I have installed webpack now I am trying to install webpack-cli but following errors occur:

    $ npm i --save-dev webpack-cli

    > webpack-cli@3.2.1 postinstall D:\Development\Practices\sample\starter\node_modules\webpack-cli
    > lightercollective

    'lightercollective' is not recognized as an internal or external command, 
    operable program or batch file.
    npm WARN starter@1.0.0 No description
    npm WARN starter@1.0.0 No repository field.

    npm ERR! Exit status 1
    npm ERR!

    npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Notes:

• I have tried restarting my command line.
• I have also tried npm cache clean --force
• And googling about an hour.
• Finally, what does that lightercollective is not recognized as.. in the above message means? Confused???

Answer 1

Install:

npm i -g lightercollective

They change stuff... you must specify version numbers when you get packages or it won't work in the future if there is some sort of a breaking change.

Answer 2

You can add lightercollective to your dependencies to solve the issue.

Official package page

"lightercollective": "^0.0.0"

Answer 3

Update webpack-cli: npm update webpack-cli --save-dev

In my situation, I went from 3.2.1 (which warned about "lightercollective") to 3.3.8. Seemed like the issue was resolved.
