类型错误 [ERR_INVALID_ARG_TYPE]：“数据”参数必须是字符串类型或 Buffer、TypedArray 或 DataView 的实例

Question

我们的构建环境目前使用 node 12.19.0 和 npm 6.14.8。当我看到节点 14.15.1（仍然是 npm 6.14.8）的新 LTS 版本可用时，我下载了它并运行我们的 webpack 构建脚本并收到此错误。新版本的节点是否抱怨一直存在但被 12.19.0 忽略的错误？

Answer 1

向 writeFileSync 添加第二个参数

代替：

fs.writeFileSync(`${folderName}/styles.css`);

做这个：-

fs.writeFileSync(`${folderName}/styles.css`, '');

它告诉 wfs 将什么内容写入文件。可以留空
