如何在 conda env 中安装软件包

Question

我使用 conda 创建了一个环境，然后向其中添加了一个包，但是当我执行 conda list 时，它没有显示在已安装包的列表中。我做了 conda list 因为我的代码无法导入我安装的包。它正在发生在其他包中，但这个例子显示了熊猫：

(myenv) manishshukla@manishs-mbp ForecastModel % conda create -n testenv

NotWritableError: The current user does not have write permissions to a required path.
  path: /Users/manishshukla/.conda/envs/.conda_envs_dir_test
  uid: 501
  gid: 20

If you feel that permissions on this path are set incorrectly, you can manually
change them by executing

  $ sudo chown 501:20 /Users/manishshukla/.conda/envs/.conda_envs_dir_test

In general, it's not advisable to use 'sudo conda'.


(myenv) manishshukla@manishs-mbp ForecastModel % sudo conda create -n testenv1

我得到以下错误：

Dataprep.py", line 4, in <module>
    import pandas as pd
ModuleNotFoundError: No module named 'pandas'

任何指针都会有所帮助。如果这很重要，这是一个 macbook，我安装了 miniconda。

尝试不使用 sudo。一般来说，你不需要 sudo 来使用 conda 安装包

问题更新后更新

权限似乎有问题。您是否尝试过遵循 conda 给您的建议而不是使用 sudo？

在创建环境之前尝试sudo chown 501:20 /Users/manishshukla/.conda/envs。 您是否可以使用 sudo 安装 conda？如果你这样做了，我建议不使用 sudo 重新安装它。
