Question

我正在尝试使用命令sudo pip install scrapy安装scrapy，但是我收到的错误消息如下：

build/temp.linux-x86_64-2.7/_openssl.c:429:30: fatal error: openssl/opensslv.h: No such file or directory
    compilation terminated.
    error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

    ----------------------------------------
Command "/usr/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-tVcVY7/cryptography/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-zyty58-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-tVcVY7/cryptography/

该错误似乎与OpenSSL有关，需要根据http://doc.scrapy.org/en/latest/intro/install.html进行安装。但是，如果我运行sudo apt-get install openssl，我会收到一条消息，表明它已经安装：

如何解决此问题以安装scrapy？

Answer 1

使用Ubuntu软件包管理器apt-get安装scrapy。 apt-get将自动处理依赖项

sudo apt-get install python-scrapy

Answer 2

正如install documentation中所述，您应该执行以下操作：

sudo apt-get install python-dev python-pip libxml2-dev libxslt1-dev zlib1g-dev libffi-dev libssl-dev

Answer 3

问题是我必须通过命令sudo apt-get install libssl-dev安装OpenSSL开发包。
