python获取文件修改时间 错误_python错误记录
raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named 'MySQLdb'
没有在__init__.py文件中导入pymysql
__init__.py
importpymysql
pymysql.install_as_MySQLdb()
goods.GoodsImage.image: (fields.E210) Cannot use ImageField because Pillow is not installed.
HINT: Get Pillow at https://pypi.python.org/pypi/Pillow or run command "pip install Pillow".
没有安装pillow
pip install pillow
缩进错误：
IndentationError: unexpected indent
pip安装超时：
1.添加超时时间
pip install 要安装的包名 --timeout 100
2.修改pip配置文件
创建pip.conf文件
mkdir~/.pip
cd~/.pip
在.pip目录下创建一个pip.conf文件
touch pip.conf
文件就创建好了(当然如果你已经有这个文件了这步可以跳过).2. 编辑pip.conf文件
sudo gedit~/.pip/pip.conf
打开pip.conf文件窗口,将以下内容复制到文件中:
[global]
timeout= 6000 #修改pip等待时间
[global]
index-url = http://pypi.douban.com/simple #换源
[install]
trusted-host=pypi.douban.com
虚拟环境创建失败
OSError: Command /home/kevin2/.virtua...ramid_p2/bin/python2 - setuptools pip wheel failed with error code 2
1.升级pip
2.换源
#在.pip目录创建并编辑pip.conf#pip安装需要使用的https加密，所以在此需要添加trusted-host
[global]
trusted-host =mirrors.ustc.edu.cn
index-url = https://mirrors.ustc.edu.cn/pypi/web/simple

pip3 install --upgrade pip setuptools不行的时候
修改了一下"sudo vim /usr/local/lib/python3.5/dist-packages/pip/_vendor/pkg_resources/__init__.py"
#orig_path.sort(key=position_in_sys_path)#module.__path__[:] = [_normalize_cached(p) for p in orig_path]
orig_path_t =list(orig_path)
orig_path_t.sort(key=position_in_sys_path)
module.__path__[:] = [_normalize_cached(p) for p in orig_path_t]
然后我试了很多种方法，而且还根据许多其他答案pip3 install --upgrade pip setuptools等等都不行，最终还是在外文的一个讨论区找到一个，修改了一下，觉得还可以：
具体来说就是编辑文件#2121~2122 : "sudo vim /usr/local/lib/python3.5/dist-packages/pip/_vendor/pkg_resources/__init__.py"
