which python
to check the installation location. After the installation is complete, type python in the terminal to verify whether the installation is successful.
2 . Install pip
1. Let's get the pip installation script first:
1
wget https://bootstrap.pypa.io/get-pip.py
If you don't have wget installed, you can go here and copy all the content, create a new get-pip.py file, Copy the content in and it is OK.

3. Modify the pip source
first enter the HOME path:

cd ~
create .pip directory:
1
mkdir .pip
create pip.conf file:
1
touch pip. conf
, you can open the pip.conf file with your favorite editor. I am using the source of v2ex, so add:
1
2
[global]
index-url = http://pypi.v2ex.com/simple
You can put The value of index-url is set to the address of its actual source.
3. Other modules are installed
1. Pillow/PIL
wants to use python to process pictures, naturally the PIL module is indispensable. Since PIL has not been updated for a long time, with the Pillow module, it depends on For PIL, the new version of pip will come with Pillow after installation, but it seems that there is no zlib module, so an error will be reported:
File "/Library/Python/2.7/site-packages/PIL/Image.py", line 1105, in paste
im.load()
File "/Library/Python/2.7/site-packages/PIL/ImageFile.py", line 190, in load
d = Image._getdecoder(self.mode, d, a, self.decoderconfig)
File "/Library/Python/2.7/site-packages/PIL/Image.py", line 389, in _getdecoder
raise IOError("decoder %s not available" % decoder_name)
IOError: decoder zip not available
因此我们需要手动重新安装:
sudo pip install -U Pillow
