这种情况，删除node_modules,重新安装试试了，尽量不用cnpm，如果还不行，报告下使用的插件版本，或者提供demo咯

GitOfZGT commented 2 years ago

@PathFun 似乎我也遇到这个问题了,配置 css: { preprocessorOptions: { less: { // 支持内联 JavaScript javascriptEnabled: true } } } 解决

缺少 javascriptEnabled: true 应该是报这种错误，他描述的是less包找不到

这段配置一直是有的，但就是报错。

GitOfZGT commented 2 years ago

在 v1.4.0.beta.5 修复，安装新版本前，先删除一次node_modules, 最好yarn.lock 也删除一次。

windows 下，已更新到beta.5 ，已删除 node_modues 和 yarn.lock，但此问题仍在。

提供的demo并未浮现上面的报错，只发现这个normal.less 文件不存在报错在这里插入图片描述

并且

GitOfZGT commented 2 years ago

或许可能是 node版本和 npm版本有差异，待测试

transtone commented 2 years ago

node-v16.13.0

看你运行的是 build，运行一下 npm run dev呢？

这个错误是运行 dev 之后，在浏览器打开页面的时候报的，不是一开始就有。

=======

是的，编译就会报错。

经测试，本机 windows 下 node-16.13.1, node-12.22.7 都会有此错误。 Linux 下 node-16.13.1 正常。

===========

v1.4.0-beta.9 已修复。
