dify本地开发环境搭建

docker是个好东西

devcontariner up 就可构建好一个本地的docker环境。和物理机的环境隔离。避免了各种奇葩的环境问题 如何进入这个容器进行开发呢？

vscode也是个好工具

  Note: This error originates from the build backend, and is likely not a problem with poetry but with gmpy2 (2.1.5) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "gmpy2 (==2.1.5)"'.
