我已经创建了一个环境，但是当我尝试将其导出时
conda env export --name ENVNAME > ENVNAME.yml
我收到以下错误消息:
InvalidVersionSpec: Invalid version '(>=': unable to convert to expression tree: ['(']

最佳答案
我遇到了类似的问题:这是由于 conda 和 pip 之间的一些(永久)不兼容。就我而言，pip 包 nb-black导致错误:正在运行 pip uninstall nb-black其次是 conda env export > environment.yml解决了它:在导出环境之前卸载黑色可能会有所帮助。
关于yaml - Conda 环境导出到 yaml 文件失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60205992/
