Django模板语言未被PyCharm识别的问题及解决方法

我使用PyCharm专业版开发Django项目，昨日离开时项目一切正常，今日打开后发现模板中的{% load static %}显示为灰色，下一行的<!doctype html>提示“Unexpected tokens”。项目本身运行无异常，仅模板出现识别问题。我采用虚拟环境开发，项目托管在GitHub，相关模板有对应截图。

已尝试以下操作但未解决问题：

• 重新安装所有依赖（依赖均已满足）
• 激活虚拟环境（状态正常）
• 确保Docker处于运行状态
• 重新扫描索引、重启项目

Dockerfile 内容 #

FROM python:3.11.4

# Install PostgreSQL development packages
RUN apt-get update && apt-get install -y libpq-dev gcc

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
COPY . /app

# Install the required dependencies
RUN pip install --no-cache-dir -r requirements.txt

# Start the Django development server
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]

解决方法 #

更新：尝试重新扫描索引、重启项目均无效，最终通过「主菜单→文件→修复IDE」清除共享索引后，问题解决。
