我想安装Lxml,然后我可以安装Scrapy.
当我今天更新我的Mac时它不会让我重新安装lxml,我收到以下错误:
In file included from src/lxml/lxml.etree.c:314:
/private/tmp/pip_build_root/lxml/src/lxml/includes/etree_defs.h:9:10: fatal error: 'libxml/xmlversion.h' file not found
#include "libxml/xmlversion.h"
^
1 error generated.
error: command 'cc' failed with exit status 1
我已经尝试使用brew来安装libxml2和libxslt,两者都安装得很好但我仍然无法安装lxml.
上次我安装时我需要在Xcode上启用开发人员工具,但由于它更新到Xcode 5,它不再给我这个选项了.
有谁知道我需要做什么？
Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/beautifulsoup4-4.6.0.dist-info'Consider using the `--user` option or check the permissions.
上面的错误是我尝试使用pip命令时得到的错误.我需要做的就是pip安装requirements.txt以使我的程序正常工作.我安装了python 2.7.1并将我的代码放在我可以使用python命令的地方.我尝试使用此命令更改权限:
chmod -R 777
但它不起作用.我在我的电脑上安装了自制软件.我还尝试使用这个链接使用虚拟环境:http: //sourabhbajaj.com/mac-setup/Python/virtualenv.html但它也给了我许可问题.有没有建议摆脱这个权限问题并成功运行pip？下面的sudo命令也不起作用.
sudo pip install -r requirements.txt
我尝试使用pip在ubuntu上安装django.但不幸的是我得到了这样的错误.谁能解释一下并告诉我一些方法来解决这个问题？

我尝试通过键入终端使用pip安装python库openpyxl:
pip install openpyxl
但它没有正确执行.它引发了一个例外:
