解决用anaconda安装scrapy后，在使用scrapy时报错

python版本为3.7

因为用anaconda安装scrapy非常方便，会自动下载所依赖的包，

所以就使用anaconda安装scrapy, 非常舒服，安装很成功

conda install scrapy

问题出现

当使用scrapy时出现报错， 这里我是创建新项目，发现报错

报错信息如下：

Traceback (most recent call last):
  File "G:\anaconda\Scripts\scrapy-script.py", line 10, in <module>
    sys.exit(execute())
  File "G:\anaconda\lib\site-packages\scrapy\cmdline.py", line 149, in execute
    cmd.crawler_process = CrawlerProcess(settings)
  File "G:\anaconda\lib\site-packages\scrapy\crawler.py", line 252, in __init__
    log_scrapy_info(self.settings)
  File "G:\anaconda\lib\site-packages\scrapy\utils\log.py", line 149, in log_scrapy_info
    for name, version in scrapy_components_versions()
  File "G:\anaconda\lib\site-packages\scrapy\utils\versions.py", line 35, in scrapy_components_versions
    ("pyOpenSSL", _get_openssl_version()),
  File "G:\anaconda\lib\site-packages\scrapy\utils\versions.py", line 43, in _get_openssl_version
    import OpenSSL
  File "G:\anaconda\lib\site-packages\OpenSSL\__init__.py", line 8, in <module>
    from OpenSSL import crypto, SSL
  File "G:\anaconda\lib\site-packages\OpenSSL\crypto.py", line 16, in <module>
    from OpenSSL._util import (
  File "G:\anaconda\lib\site-packages\OpenSSL\_util.py", line 6, in <module>
    from cryptography.hazmat.bindings.openssl.binding import Binding
  File "G:\anaconda\lib\site-packages\cryptography\hazmat\bindings\openssl\binding.py", line 13, in <module>
    from cryptography.hazmat.bindings._openssl import ffi, lib
ImportError: DLL load failed: 操作系统无法运行 %1。

其中最关键的报错应该是最后一个

File “G:\anaconda\lib\site-packages\cryptography\hazmat\bindings\openssl\binding.py”, line 13, in

from cryptography.hazmat.bindings._openssl import ffi, lib

解决方法

把你安装路径下的libeay32.dll和ssleay32.dll，放到C:\windows\system32

比如我的安装路径是

G:\anaconda\pkgs\openssl-1.0.2o-h2c51139_0\Library\bin

如果找不到 你可以使用everything这个软件(比系统自带的搜索好用多了，而且小)搜索libeay32.dll，找到相应路径

然后把文件复制到

C:\Windows\System32

路径下， 问题解决！
