我正在尝试使用 easy_install -U Scrapy 安装 Scrapy，但在尝试安装时出现奇怪的错误“无法打开包含文件”。有谁知道发生了什么事？这是我的完整回溯:

最佳答案
我在安装不同的 python 应用程序时遇到了同样的错误。我缺少 OpenSSL 开发包，解决方法是:
sudo apt-get install libssl-dev
关于python - Scrapy 安装失败，出现错误 'cannot open include: ' openssl/aes.h '，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25568566/
