less.js: Class constructor FileManager cannot be invoked without 'new'.
It seems that v3.10.0 breaks my build, webpack logs below:
ERROR in ./src/pages/score/components/current/no-join/index.less
Module build failed (from ./node_modules/_mini-css-extract-plugin@0.5.0@mini-css-extract-plugin/dist/loader.js):

Everything is ok when downgrade to v3.9.0, please investigate this issue and hope to fix it as soon as possible.

I have the same problem，you mast change you ‘package.json’ => “less”: “~3.9.0”, limit version
可以把package.json中 less版本的 ^ 去掉 重新安装一下 v3.9.0 应该就可以解决问题 大家可以试一下
虽然 锁定了版本 但是由于 ^, 所以会下载3 一下的最新版本， 最新版本应该是有问题的。
just use less-loader@5.0.0 every thing will be ok
This is an issue with an older version of
less-loader, not Less, which did not inherit the Less filemanager correctly.less-loader5.0 does. See: https://github.com/less/less.js/issues/3414#issuecomment-522223041@montanaflynn you can also fix the problem by specifying a sub version for
less-loadertemporarily:Manually specify less version ： npm i less@3.9.0 -D
ok!!!
你可以，把你package.js 里的less依赖，重新安装最近小版本依赖。
use
"less": "~3.9.0"Same here. npm picks up this “minor” release automatically, and breaks all of my builds. 😦
+1 version less 3.9.0 less-loader 4.1.0

Incidentally, for those watching this thread, I’ll re-open and probably submit a fix later today for older
less-loaderversions, just to have things be less annoying.It’s one of those edge cases where actually using the
Classsyntax to replace a prototype function throws an error withoutnew. A FileManager is supposed to always be invoked withnew(that’s the documented API), and older versions ofless-loaderapparently did not.Again, though, if you’re looking at the thread, just updating to
less-loader5.0 fixes this incompatibility.It’s not a node version issue.
Why does this problem arise? Node.js version is not right?
