坑1：linux用django startproject報錯??
[root@iZo4t6je6mwbb8Z django]# django-admin.py startproject demo1
Traceback (most recent call last):
File "/usr/local/lib/python3.6/site-packages/django/bin/django-admin.py", line 5, in <module>
from django.core import management
ImportError: No module named django.core
原因：
linux默認(rèn)是有python2的阳惹，但我又安裝了python3砚著，django是在python3的lib里筛婉，所以執(zhí)行django-admin.py startproject learn辩棒，調(diào)用的python環(huán)境是python2的涝影，所以找不到core.management嗤详。
解決方案：
cd /usr/bin
mv python python2 #原先的python是python2.7的軟連接
mv python3 python #現(xiàn)在修改python為python3
實際演示：
[root@iZo4t6je6mwbb8Z django]# cd /usr/bin
[root@iZo4t6je6mwbb8Z bin]# mv python python2
mv: overwrite ‘python2’? y
[root@iZo4t6je6mwbb8Z bin]# mv python3 python
[root@iZo4t6je6mwbb8Z bin]# cd /home/liujia/django
[root@iZo4t6je6mwbb8Z django]# django-admin.py startproject demo1
[root@iZo4t6je6mwbb8Z django]# ls
demo1
[root@iZo4t6je6mwbb8Z django]# cd demo1
[root@iZo4t6je6mwbb8Z demo1]# ls
demo1 manage.py
[root@iZo4t6je6mwbb8Z demo1]#
坑2：python manage.py runserver報錯：SQLite 3.8.3 or later is required (found 3.7.17)
原因：
阿里云自帶的centos的sqlite版本低了
解決方案：
＃更新SQLite 3

坑3：無法直接使用pip3或pip命令
原因：
未知
解決方案1：
使用python -m pip代替
解決方案2：另一個懷疑能解決的方案是安裝libffi-devel贮懈，然后重新從./configure這一步開始重新安裝python
yum install libffi-devel
坑4：安裝uwsgi報錯：plugins/python/uwsgi_python.h:2:20: fatal error: Python.h: No such file or directory
原因：
未知
解決方案：
yum install python-devel.x86_64
坑5：安裝uwsgi報錯：ModuleNotFoundError: No module named '_ctypes'
yum install libffi-devel
從./configure這一步開始重新安裝python
坑6：uwsgi啟動報錯：probably another instance of uWSGI is running on the same address
可以用命令殺掉這個端口在重啟：
sudo fuser -k 8080/tcp
坑7：安裝uwsgi報錯：Command "/usr/bin/python3 -u -c "import setuptools, tokenize;file='/tmp/pip-build-zcnqe9e2/uwsgi/setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" install --record /tmp/pip-f2pzir0h-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-zcnqe9e2/uwsgi/
yum install python3-devel -y
坑8：Invalid block tag on line 23: 'translate'
vi 到具體文件，執(zhí)行替換命令：
:%s#translate#trans#g
