有没有人遇到过同样的问题或知道如何解决它？ 更新系统后，我遇到了很多问题。

系统：MacOS Catalina V10.15.3

Answer 1

我已经通过卸载“整个”python 并使用 conda 重新安装来解决这个问题。 我认为问题可能与其他 conda python 3.7 包有关，

conda remove --force

Answer 2

我在使用“Conda Install”安装 Conda Packages 时遇到了同样的问题，这是解决方案.. 从命令行安装程序安装 Anaconda

bash ~(/Path/to/file).sh 即使你没有使用 bash 作为默认值。 macOS Catalina 的默认值是 Zsh

转到 >> 系统偏好设置 >> 隐私与安全 >>全盘访问

为 Anaconda Navigator 提供“全盘访问”。 它在 macOS Catalina 中对我有用。 我什至尝试过sudo chmod 776 (Path to Anaconda)但没有用。 这适用于 miniconda3。 不兼容包的问题可以通过使用Conda update -all或 downgrade 更新 Conda 来解决，如果您使用conda downgrade安装旧包
