gem install nokogiri -v '1.6.8.1' không thành công

Question

Tạo ứng dụng Rails mới và gặp vấn đề với nokogiri. Đã nói thử gem install nokogiri -v '1.6.8.1' không thành công với đầu ra bên dưới. Tôi đã thử xóa Gemfile.lock và sử dụng Gemfile từ một ứng dụng khác mà không có vấn đề - bundle install vẫn không thành công. Lỗi ban đầu là bundle install tiếp tục hoạt động trong các ứng dụng khác.

Từ giao diện điều khiển:

gem install nokogiri -v '1.6.8.1'

IMPORTANT NOTICE: 

Building Nokogiri with a packaged version of libxml2-2.9.4. 

Team Nokogiri will keep on doing their best to provide security 
updates in a timely manner, but if this is a concern for you and want 
to use the system library instead; abort this installation process and 
reinstall nokogiri as follows: 

    gem install nokogiri -- --use-system-libraries 
     [--with-xml2-config=/path/to/xml2-config] 
     [--with-xslt-config=/path/to/xslt-config] 

If you are using Bundler, tell it to use the option: 

    bundle config build.nokogiri --use-system-libraries 
    bundle install 

Note, however, that nokogiri is not fully compatible with arbitrary 
versions of libxml2 provided by OS/package vendors.

Answer 1

Tôi cố gắng @ giới thiệu the_basterd của. Điều đó không hiệu quả, nhưng tham khảo là tốt — cảm ơn bạn the_basterd. Có gì làm việc từ tài liệu tham khảo đó là:

brew install libxml2

bundle config build.nokogiri --use-system-libraries --with-xml2-include=/usr/local/opt/libxml2/include/libxml2

tham khảo: https://github.com/sparklemotion/nokogiri/issues/1483

đăng Sau đó tại ref mà nói rằng những gì tôi đăng tải trên "được khuyến khích mạnh mẽ chống lại bởi Nokogiri"

brew unlink xz; bundle install; brew link xzđược ưu tiên.

Bạn cũng có thể gặp thông báo lỗi tương tự nếu bạn đã tải xuống Công cụ XCode nhưng chưa đồng ý với giấy phép.

Từ Terminal, chạy:

sudo xcodebuild -license 

Nhập mật khẩu quản trị của bạn, không gian thông qua thỏa thuận và gõ agree để chấp nhận. Chạy brew doctor và nếu cần, brew update và bạn sẽ ở trạng thái tốt.

Answer 4

Tôi gặp sự cố này với nokogiri-1.6.8.1 khi sử dụng bundle install --path vendor/bundle để cài đặt trực tiếp vào một dự án nằm trong thư mục đồng bộ hóa Google Drive. Việc gác máy dường như liên quan đến libxml2.

Trong khi đọc qua vấn đề GitHub được tham chiếu bởi @Greg và @the_basterd, tôi nhận thấy rằng someone was having trouble installing into a Box sync folder. Di chuyển thư mục dự án của tôi đến một vị trí khác đã hoạt động.

Không chắc chắn vấn đề cơ bản là khi cài đặt vào một thư mục đồng bộ hóa, nhưng tôi muốn được quan tâm để tìm hiểu xem có ai có bất kỳ suy nghĩ nào không.

Chưa thử nghiệm điều này với Dropbox, nhưng có lẽ điều đó cũng sẽ gây ra sự cố.
