Question

我尝试在我的Windows cmd上安装flask，并在安装MarkupSafe模块时遇到UnicodeDecodeError

Exception:
Traceback (most recent call last):
  File "c:\python36\lib\site-packages\pip\compat\__init__.py", line 73, in console_to_str
    return s.decode(sys.__stdout__.encoding)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 5: invalid continuation byte

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
 File "c:\python36\lib\site-packages\pip\basecommand.py", line 215, in main
   status = self.run(options, args)

   return s.decode('utf_8')

问题来自于Pypi上MarkupSafe丢失的轮子。这是解决方法（Windows上的git-bash）：

pip install /c/tmp/markupsafe/dist/MarkupSafe-1.0-cp36-cp36m-win_amd64.whl

在您需要使用它的其他项目中，只需致电

即可

    protected override void OnModelCreating(ModelBuilder builder)
    {
        builder.Entity<Appoiment>().HasOne(a => a.ApplicationUser)
                .WithMany(au => au.Appointments)
                .HasForeignKey(a => a.ApplicationUserId)
                .IsRequired(false);

    }
