ubuntu与mac环境安装pyspider出现的问题以及解决方案

ubuntu下安装

• 一般会出现pycurl安装不了的问题，执行:

$ apt-get install python python-dev python-distribute python-pip \
libcurl4-openssl-dev libxml2-dev libxslt1-dev python-lxml \ 
libssl-dev zlib1g-dev

$ pip install pyspider

Mac系统

$ pip install pyspider

遇到安装不了pycurl错误:

$ sudo env ARCHFLAGS="-arch x86_64" LDFLAGS="-L/usr/local/opt/openssl/lib" pip install pycurl

• 遇到类似command 'clang' failed with exit status 1的错误:

$ brew install openssl

• 仍然有错会提醒你升级openssl：

$ brew upgrade openssl

• 写入环境变量:

$ echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

然后再尝试安装最上面的那个命令

• 遇到这个错误:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

尝试这个命令：

$ xcode-select --install

• 再遇到这个错误：

pycurl: libcurl link-time ssl backend (openssl) is different from compile-time ssl backend (none/other)

执行下面的操作：

$ pip uninstall pycurl

$ export PYCURL_SSL_LIBRARY=openssl

$ pip install pycurl

$ pip install pyspider

这就是mac可能遇到的错误了
