我是Python的新手,想在Mac上为Python 3.5安装Pillow软件包.我使用pip install pillowcommand并收到此错误：
Jaspers-MBP:~ jasperherrmann$pip install pillow
Collecting pillow
Using cached Pillow-5.1.0-cp27-cp27m-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_10_10_intel.macosx_10_10_x86_64.whl
prompt-toolkit 1.0.15 has requirement six>=1.9.0, but you'll have six
1.4.1 which is incompatible.
pandas 0.22.0 has requirement numpy>=1.9.0, but you'll have numpy 1.8.0rc1 which is incompatible.
html5lib 1.0.1 has requirement six>=1.9, but you'll have six 1.4.1 which is incompatible.
matplotlib 1.3.1 has requirement numpy>=1.5, but you'll have numpy 1.8.0rc1 which is incompatible.
jupyter-client 5.2.3 has requirement python-dateutil>=2.1, but you'll have python-dateutil 1.5 which is incompatible.
Installing collected packages: pillow
所以我继续尝试安装pandas六,pip install numpy和pip install python-dateutil所需的所有东西pandas,html5lib等,并得到下一个错误(对于所有命令相同)：
Jaspers-MBP:~ jasperherrmann$pip install six
Requirement already satisfied: six in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python (1.4.1)
prompt-toolkit 1.0.15 has requirement six>=1.9.0, but you'll have six 1.4.1 which is incompatible.
pandas 0.22.0 has requirement numpy>=1.9.0, but you'll have numpy 1.8.0rc1 which is incompatible.

jupyter-client 5.2.3 has requirement python-dateutil>=2.1, but you'll have python-dateutil 1.5 which is incompatible.
所以我以为所有其他六种都已经存在,而我只需要使用pip install –upgrade six命令对其进行升级.这是我遇到的最后一个错误,现在不知道如何继续：
Jaspers-MBP:~ jasperherrmann$pip install --upgrade six
Collecting six

Installing collected packages: six
Found existing installation: six 1.4.1
Cannot uninstall 'six'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
Jaspers-MBP:~ jasperherrmann$
所以在这里我很困惑,如果你们中的一些人对我的问题有解决的办法,我会很高兴的:-)
解决方法:
只需做pip install –ignore安装的枕头,就可以解决您的问题.
