- setuptools_scm 问题
distutils.errors.DistutilsError: Could not find suitable distribution for Requirement.parse('setuptools_scm~=3.2.0')解决方法：
pip install setuptools_scm~=3.2.0说明
通过学习源码的编译我们可以进一步了解edgedb 的工作原理,对于启动可以进一步学习源码，了解启动的处理逻辑，目前直接运行edgedb-server
是有问题的，实际上因为后端是使用的pg 需要配置类似pg 的相关参数，实际我们可以解决systemd 的管理文件
