当我在mac os上使用pip安装mysql-python时,我总是得到这个错误,我如何解决这个问题?

它是Django deb模型的简化重新实现。 这是可行的(类似于Django所做的,尽管它是一个属性,而不是一个属性): class ClassPropertyType(type):
@property
def objects(cls):
return cls.init_empty_storage_if_needed()
class Model(metaclass=ClassPropertyType):
@classmethod
def init_empty_storage_if_needed(cls):

当加载python扩展时打开vscode终端时,它尝试执行以下操作:
source /Users/victor/.pyenv/shims/activate.sh
触发此错误:
pyenv: activate.sh command not found
The `activate.sh` command exists in these Python versions:

然后直截了当地关闭终端。我这里的pyenv装置有问题吗?
上下文:
which python > /Users/victor/.pyenv/shims/pythonpython --verison >
