下面是Python3.7安装pyspider的方式,能安装成功但是后期有很多问题,所以不建议,请使用3.5版本的Python进行安装!!!由于要做爬虫工作,所以学习
pyspider
框架,下面介绍安装步骤以及安装过程中遇到的问题。系统环境如下:
- 64位win10系统
- Python3.7
用pip
命令安装pyspider
,命令pip install pyspider
进行安装,但是重点来了:报错!!!错误大概如下:
“Command "python setup.py egg_info" failed with error code 10”...
Your are using pip version 10.0.1, however version 18.0 is available...
所以接下来升级pip版本,执行命令 python -m pip install --upgrade pip
PS D:pythondemo> pip install pyspider

提示成功后再次执行pip install pyspider
进行安装,但是又双叒叕报错!!!错误不提示pip
版本问题了:
Command "python setup.py egg_info" failed with error code 10 in C:UsersxxxAppDataLocalTemppip-install-tc5uvu7lpycurl
经过网上大拿的经验需要安装wheel
,执行命令pip3 install wheel
安装,提示Successfully installed wheel-0.31.1
代表安装成功,然后访问https://www.lfd.uci.edu/~gohlke/pythonlibs/下载相关安装文件,具体如下:
PycURL, a interface to the libcurl library.
pycurl‑7.43.1‑cp27‑cp27m‑win32.whl
pycurl‑7.43.1‑cp27‑cp27m‑win_amd64.whl
pycurl‑7.43.1‑cp34‑cp34m‑win32.whl
pycurl‑7.43.1‑cp34‑cp34m‑win_amd64.whl
pycurl‑7.43.1‑cp35‑cp35m‑win32.whl
pycurl‑7.43.1‑cp35‑cp35m‑win_amd64.whl
pycurl‑7.43.1‑cp36‑cp36m‑win32.whl
pycurl‑7.43.1‑cp36‑cp36m‑win_amd64.whl
pycurl‑7.43.1‑cp37‑cp37m‑win32.whl
pycurl‑7.43.1‑cp37‑cp37m‑win_amd64.whl
具体下载版本根据你使用的环境来定,比如我的是python3.7,然后python是32位版本,则需要选择pycurl‑7.43.1‑cp37‑cp37m‑win32.whl
进行下载,注意:32或64位版本不是电脑的版本,是安装python的版本!!!
下载后进行安装,命令 pip3 install D:pythondemopycurl-7.43.1-cp37-cp37m-win_amd64.whl
执行,如果报错:
pycurl-7.43.1-cp37-cp37m-win_amd64.whl is not a supported wheel on this platform.
代表你安装的版本不对,就是上面所述的那个,我电脑是64位的,python是32位的,所以报错,然后下载pycurl‑7.43.1‑cp37‑cp37m‑win32.whl
后再执行命令pip3 install D:pythondemopycurl-7.43.1-cp37-cp37m-win32.whl
安装即可,提示Successfully installed pycurl-7.43.1
及安装成功!
费了很大事,最后再安装pyspider
就OK了,执行命令 pip3 install pyspider
提示
Successfully installed Flask-1.0.2 Flask-Login-0.4.1 Jinja2-2.10 MarkupSafe-1.0 PyYAML-3.13 Werkzeug-0.14.1 click-6.7 cssselect-1.0.3 defusedxml-0.5.0 itsdangerous-0.24 jsmin-2.2.2 lxml-4.2.5 pyquery-1.4.0 pyspider-0.3.10 tblib-1.3.2 tornado-4.5.3 u-msgpack-python-2.5.0 wsgidav-2.4.1
大功告成!!!
小结:安装过程中遇到上述问题不要急,一步一步去解决,百度不行就Google,总会有办法的,毕竟咱们不是第一个吃螃蟹的人!
