如果我在npm run dev部分中添加以下代码，则_mobmenu.scss之后有错误当这部分代码被注释时，我没有错误。
@keyframes openbt {
from { :before { content: '\f0c9'; } }
to { :before { content: '\e804'; } }
}
@keyframes closebt {
from { :before { content: '\f0c9'; } }
to { :before { content: '\e804'; } }
}
.openbt:before {
animation: openbt 2s;
content: '\e804';
}
.closebt:before {
animation: closebt 2s;
content: '\f0c9';
}
我不知道在这里应该是哪个号码。

代码中的问题是您的scss语法，在关键帧中无需在后面提到，因为您已经将动画应用到了它。
像这样正确。
@keyframes openbt {
from {
content: '\f0c9';
}
to {
content: '\e804';
}
}
@keyframes closebt {
from {
content: '\f0c9';
}
to {
content: '\e804';
}
}
.openbt{
&:before {
animation: openbt 2s;
content: '\e804';
}
}
.closebt{
&:before {
animation: closebt 2s;
content: '\f0c9';
}
}
检查此运行示例
@-webkit-keyframes changeLetter {
0% {
content: "1";
}
100% {
content: "2";
}
}
@keyframes changeLetter {
0% {
content: "1";
}
100% {
content: "2";
}
}
.element {
display: -webkit-box;
display: flex;
-webkit-box-align: center;
align-items: center;
-webkit-box-pack: center;
justify-content: center;
min-height: 100vh;
}
.element:after {
-webkit-animation: changeLetter 3s linear infinite alternate;
animation: changeLetter 3s linear infinite alternate;
display: block;
content: "A";
font-size: 80px;
}<div class="element"></div>以上正在运行的示例在CSS中，这是相同的SCSS，不管它的CSS还是SCSS，逻辑都将保持不变。
@keyframes changeLetter {
0% {
content: "1";
}
100% {
content: "2";
}
}
.element {
display: flex;
align-items: center;
justify-content: center;
min-height: 100vh;
&:after {
animation: changeLetter 3s linear infinite alternate;
display: block;
