无法激活现有的 conda 环境

Question

我在 Pycharm 中创建了一个名为 Practice using Python3.7 的 Conda 环境。我使用的是 Mac 并使用 Pycharm 终端 (fish)，但是使用 iterm2 时收到相同的错误。

当我输入时，conda activate Practice我收到以下错误：

An unexpected error has occurred. Conda has prepared the above report.

我已经运行conda init fish并重新启动了 shell，甚至尝试重新启动机器，但仍然收到相同的错误。

这个问题阻止我运行代码，因为我的项目解释器已配置到此环境，但每当我尝试安装软件包时，它都会安装到活动环境（基础）。

我有同样的问题。请注意/usr/local/anaconda3/bin在您的PATH中出现了两次。确保您自己没有将该目录放在您的路径上。

在您的 Fish 配置中添加conda init fish一行，该行将创建一个“conda”shell 函数，并且通过将/usr/local/anaconda3/bin附加到您的PATH，您会干扰一些假设conda init。
