当我试图在vercel上部署我的django应用程序时出错

  •  0
  • Emilio  · 技术社区  · 2 年前

    我在django上构建我的应用程序,所有依赖项都在文件“requirements.txt”中指定

    我没有在vercel上创建环境变量来部署,因为我看到了一个教程,里面的人没有。 我有两个名为build_files.sh和vercel.json的文件

    build_files.sh:

    pip install -r requirements.txt
    python3 manage.py collectstatic --noinput
    

    vercel.json:

    {
        "version": 2,
        "builds": [
          {
            "src": "gestor_backend/wsgi.py",
            "use": "@vercel/python",
            "config": {
              "maxLambdaSize": "15mb",
              "runtime": "python3.8"
            }
          },
          {
            "src": "build_files.sh",
            "use": "@vercel/static-build",
            "config": {
              "distDir": "staticfiles"
            }
          }
        ],
        "routes": [
          {
            "src": "/static/(.*)",
            "dest": "/static/$1"
          },
          {
            "src": "/(.*)",
            "dest": "gestor_backend/wsgi.py"
          }
        ]
      }
    

    requirements.txt:

    asgiref==3.7.2
    backports.zoneinfo==0.2.1
    certifi==2024.2.2
    cffi==1.16.0
    charset-normalizer==3.3.2
    cryptography==42.0.5
    defusedxml==0.8.0rc2

    sqlparse==0.4.4
    typing_extensions==4.9.0
    tzdata==2023.4
    urllib3==2.2.1
    

    这就是全部错误

    从你的 stderr 输出:

    你可以看到 pkg-config 找不到名称,它告诉您手动设置这些环境变量。这很可能是 mysqlclient 未被建造/发现。

    在the main.yml 的 Github操作 您可以看到,我正在将这些导出为环境变量。
