Python 刮片错误--导入错误：未加载库

我正试图用Scrapy做我的第一部分工作，使用的是来自的一个非常简单的演示，我得到一个ImportError：库未加载，如下所示

gchrist1$ scrapy crawl dmoz

但后者没有：

但我还是犯了同样的错误。我还尝试了在 但也犯了同样的错误

导入错误：dlopen（/Users/gchrist1/anaconda/lib/python2.7/site-packages/cryptography/hazmat/bindings//u openssl.so，2）：未加载库：libcrypto.1.0.0.dylib

在OSX上，Python和Scrapy等各种包可能都应该使用一个新的库，以便在运行时找到库的正确版本。听起来好像他们在构建/安装期间没有使用它

对libcrypto.1.0.0.dylib执行查找：

find <some directory> -name libcrypto.1.0.0.dylib

find-name libcrypto.1.0.0.dylib

---

获得路径后，在运行其他程序之前，使用设置路径

DYLD\u LIBRARY\u PATH

类似于Linux。另请参阅苹果的手册页。

也许您应该尝试升级

pip

，然后重新开始：

easy_install -U pip

easy_install -U pip
