我正在尝试下载 NLTK 3.0 以在 Mac OS X 10.7.5 上与 Python 3.6 一起使用,但出现 SSL 错误:
I am trying to download NLTK 3.0 for use with Python 3.6 on Mac OS X 10.7.5, but am getting an SSL error:
import nltk
nltk.download()
我使用 pip3 命令下载了 NLTK:sudo pip3 install -U nltk
.
I downloaded NLTK with a pip3 command: sudo pip3 install -U nltk
.
更改 NLTK 下载器中的索引允许下载器显示所有 NLTK 的文件,但是当尝试下载所有文件时,会出现另一个 SSL 错误(见照片底部):
Changing the index in the NLTK downloader allows the downloader to show all of NLTK's files, but when one tries to download all, one gets another SSL error (see bottom of photo):
我对计算机科学比较陌生,对 SSL 一点也不了解.
I am relatively new to computer science and am not at all savvy with respect to SSL.

NLTK 下载 SSL:证书验证失败
使用 nltk.download() 下载错误
如果您运行以下终端命令,则无需禁用 SSL 检查:
You don't need to disable SSL checking if you run the following terminal command:
/Applications/Python 3.6/Install Certificates.command
在 3.6
的位置,如果它是较早的版本,请放置您的 Python 版本.然后你应该能够打开你的 Python 解释器(使用命令 python3
)并在那里成功运行 nltk.download()
.
In the place of 3.6
, put your version of Python if it's an earlier one. Then you should be able to open your Python interpreter (using the command python3
) and successfully run nltk.download()
there.
