Sự cố khi cập nhật anaconda và cài đặt các gói mới

Question

Tôi đang cố gắng cài đặt seaborn trên anaconda trên Ubuntu-Linux.

conda install -c anaconda seaborn=0.7.1 

Tôi nhận được thông báo lỗi sau:

Bất kỳ ý kiến ​​gì vấn đề có thể ở đây? Rất cám ơn trước.

Answer 1

xin vui lòng xem tại đây: https://github.com/conda/conda/issues/3929

Vấn đề là một phiên bản cũ của gói mã hóa. Nó có thể được cố định bằng cách chạy:

CONDA_SSL_VERIFY=false conda update pyopenssl 

Answer 2

Một cách khác để vô hiệu hóa xác minh giấy chứng nhận SSL mà sẽ làm việc trên Windows cũng như:

thêm ssl_verify: False-.condarc tập tin.

.condarc tệp không được bao gồm theo mặc định nhưng tệp được tự động tạo trong thư mục chính của người dùng trong lần đầu tiên bạn chạy lệnh conda config.

Để thiết ssl_verify lệnh sau đây có thể được sử dụng:

conda config --set ssl_verify False.
