在 Ubuntu 虚拟环境中安装 scrypt-0.7.1 时出现问题

我正在尝试安装 python 包加密进入我在 Ubuntu 下的虚拟 Python 环境。我不太明白错误消息。我该怎么做才能让它工作？

答案1

两个错误消息，两个答案：

  1. 只需运行以下命令即可安装 ssl 开发库

    sudo apt-get install libssl-dev

    为什么？

    从错误信息来看：

    scrypt-1.1.6/lib/crypto/crypto_aesctr.c:38:25: fatal error: openssl/aes.h: Datei oder Verzeichnis nicht gefunden
#include <openssl/aes.h>

    哪里openssl/aes.h？

    % apt-file search openssl/aes.h
libssl-dev: /usr/include/openssl/aes.h

  2. 另一个错误信息

    /home/nuc/Dropbox/Julie/julie/lib/python2.7/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
  InsecurePlatformWarning

    使用此命令

    conda install cryptography
pip install 'requests[security]'

    或者使用 Python > 2.7.9
