【windows cookiecutter安装fastapi 模板】

在使用cookiecutter安装fastapi的web项目模板时，发生报错，网上没有太多相关的记录，故记录下解决方法

1. 安装cookiecutter包
   pip install cookiecutter

2. 获取fastapi模板
   cookiecutter https://github.com/tiangolo/full-stack-fastapi-postgresql
   安装失败，报错如下：

   Traceback (most recent call last):
     File "D:\project\anaconda\envs\speak_test\lib\runpy.py", line 196, in _run_module_as_main
       return _run_code(code, main_globals, None,
     File "D:\project\anaconda\envs\speak_test\lib\runpy.py", line 86, in _run_code
       exec(code, run_globals)
     File "D:\project\anaconda\envs\speak_test\Scripts\cookiecutter.exe\__main__.py", line 7, in <module>
     File "D:\project\anaconda\envs\speak_test\lib\site-packages\click\core.py", line 829, in __call__
       return self.main(*args, **kwargs)
     File "D:\project\anaconda\envs\speak_test\lib\site-packages\click\core.py", line 782, in main
       rv = self.invoke(ctx)
     File "D:\project\anaconda\envs\speak_test\lib\site-packages\click\core.py", line 1066, in invoke
       return ctx.invoke(self.callback, **ctx.params)

     File "D:\project\anaconda\envs\speak_test\lib\site-packages\cookiecutter\main.py", line 67, in cookiecutter
       repo_dir, cleanup = determine_repo_dir(
     File "D:\project\anaconda\envs\speak_test\lib\site-packages\cookiecutter\repository.py", line 110, in determine_repo_dir
       cloned_repo = clone(
     File "D:\project\anaconda\envs\speak_test\lib\site-packages\cookiecutter\vcs.py", line 101, in clone
       subprocess.check_output(
     File "D:\project\anaconda\envs\speak_test\lib\subprocess.py", line 420, in check_output
       return run(*popenargs, stdout=PIPE, timeout=timeout, check=True,
     File "D:\project\anaconda\envs\speak_test\lib\subprocess.py", line 524, in run
       raise CalledProcessError(retcode, process.args,
   subprocess.CalledProcessError: Command '['git', 'clone', 'https://github.com/tiangolo/full-stack-fastapi-postgresql']' returned non-zero exit status 128.
   

3. 修改cookiecutter的源代码，不让它退出，找到出错的原因
   File "D:\project\anaconda\envs\speak_test\lib\subprocess.py", line 420, in check_output return run(*popenargs, stdout=PIPE, timeout=timeout, check=True,
   修改该句，把check=True改为ckeck=False

4. 再次执行cookiecutter https://github.com/tiangolo/full-stack-fastapi-postgresql
   报错如下：

   A valid repository for "https://github.com/tiangolo/full-stack-fastapi-postgresql" could not be found in the following 	locations:
   C:\Users\fortune\.cookiecutters\full-stack-fastapi-postgresql
   

5. 到git网站上下载包，然后手动替换
   
   解压并放到指定路径，记得修改文件名
   这里我解压到C:\Users\fortune.cookiecutters\full-stack-fastapi-postgresql，文件夹名称是full-stack-fastapi-postgresql
   

6. 执行cookiecutter https://github.com/tiangolo/full-stack-fastapi-postgresql
You've downloaded C:\Users\fortune\.cookiecutters\full-stack-fastapi-postgresql before. Is it okay to delete and re-download it? 该选项选择no
   Do you want to re-use the existing version? [yes]: yes 选择yes
   随后都是配置项了

初始化项目时需要用到的openssl模块，可以参考
openssl安装教程的第二种方法，下载exe文件后直接安装并配置好环境变量，最后使用openssl rand -hex 32命令获取一个key用作secret_key和password。
