Question

我在mac OS X的终端上输入nltk.download()后运行了命令python3。然后我收到此错误

PermissionError: [Errno 13] Permission denied: '/Users/shreya/nltk_data/corpora/panlex_swadesh.zip'

这是我在终端上得到的：

Answer 1

您对此文件的权限有误。您需要使用sudo执行脚本，或者最好通过运行此命令来更改权限：

sudo chmod +rwx /Users/shreya/nltk_data/corpora/panlex_swadesh.zip

此外，如果要更改目录中的所有权限，可以运行：

sudo chmod -R +rwx /Users/shreya/nltk_data/

Answer 2

出于某种原因，您的python下载过程无权将文件下载到nltk_data目录中。这很清楚。由于后者位于您的主目录下（假设您用户shreya），因此无法确定可能出现的问题。您可以编辑您的答案以提供更多信息，包括您正在运行的OS X版本以及可能与您的环境相关的任何其他信息。

您也可以尝试不同的方法：

删除整个nltk_data文件夹，退出并重新启动Python，然后重试。
指示交互式下载程序将文件放在不同的目录中（请参阅底部的字段）。
启动IDLE（例如，在终端输入idle或idle3）并在IDLE控制台中运行您的python代码。

也许其中一个会起作用。如果没有，您将以提供更多信息。
