Answer 1

我在安装不同的python应用程序时遇到了同样的错误。我错过了OpenSSL开发包，解决了：

sudo apt-get install libssl-dev

Answer 2

在OSX上

如果您被告知未创建链接，则

brew install openssl然后可能brew link openssl --force。

使用以下命令安装Scrapy

env CRYPTOGRAPHY_OSX_NO_LINK_FLAGS=1 LDFLAGS="$(brew --prefix openssl)/lib/libssl.a $(brew --prefix openssl)/lib/libcrypto.a" CFLAGS="-I$(brew --prefix openssl)/include" pip install scrapy

如果您愿意，可以将openssl替换为libressl。

Answer 3

安装openssl

就足够了

brew install openssl

并导出

export LDFLAGS=-L/usr/local/opt/openssl/lib
export CPPFLAGS=-I/usr/local/opt/openssl/include

在。尽量避免与--force参数链接，因为它可能导致与系统库的冲突。

Answer 4

对于所有在安装scrapy时遇到错误的人都应该遵循http://community.spiceworks.com/how_to/38490-setting-up-scrapy-on-windows-7。此链接描述了安装scrapy的最准确，最简单的方法，而不会在Windows 7和8上遇到任何错误。
