我正在尝试编译laravel sass文件以应用更改，但是每次我运行（private void DataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
if (dataGridView1?.CurrentCell?.OwningColumn?.Name != "CategoryIdColumn")
return;
var combo = e.Control as DataGridViewComboBoxEditingControl;
if (combo == null)
return;
combo.DrawMode = DrawMode.OwnerDrawFixed;
combo.DrawItem += (obj, args) =>
{
var txt = args.Index >= 0 ? combo.GetItemText(combo.Items[args.Index]) : "";
var textColor = args.Index == 0 ? SystemColors.GrayText : SystemColors.ControlText;
var font = args.Index == 0 ? new Font(combo.Font, FontStyle.Italic) : combo.Font;
if ((args.State & DrawItemState.Selected) == DrawItemState.Selected)
{
textColor = SystemColors.HighlightText;
}
args.DrawBackground();
TextRenderer.DrawText(args.Graphics, txt, font,
args.Bounds, textColor,
TextFormatFlags.VerticalCenter | TextFormatFlags.Left);
};
}
或（private void DataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
if (e.ColumnIndex < 0 || e.RowIndex < 0 ||
dataGridView1.Columns[e.ColumnIndex].Name != "CategoryIdColumn")
return;
if (dataGridView1[e.ColumnIndex, e.RowIndex].Value == DBNull.Value)
{
e.CellStyle.Font = new Font(e.CellStyle.Font, FontStyle.Italic);
e.CellStyle.ForeColor = SystemColors.GrayText;
}
else
{
e.CellStyle.Font = new Font(e.CellStyle.Font, FontStyle.Regular);
e.CellStyle.ForeColor = SystemColors.ControlText;
}
}
）时，我都会遇到这些错误...

问题在于此错误是因为没有 node_modules 。
您必须运行 npm install 来下载Laravel Mix所需的所有软件包。
如果您具有 node_module 文件夹，则将其删除并再次运行 npm install 。
