Namecheap CPanel（Python应用）安装Python包遇问题求助

1. 依赖安装错误 #

使用requirements.txt安装依赖时出现以下错误：

error: subprocess-exited-with-error    
× Getting requirements to build wheel did not run successfully.  
│ exit code: 1  
╰─> See above for output.    
note: This error originates from a subprocess, and is likely not a problem with pip.
error: subprocess-exited-with-error
× Getting requirements to build wheel did not run successfully.
│ exit code: 1
╰─> See above for output.
note: This error originates from a subprocess, and is likely not a problem with pip.

2. requirements.txt内容 #

firebase
firebase_admin
Flask
Flask_Cors
pypdfium2
Pyrebase4
Werkzeug

3. 手动运行应用的语法错误 #

手动启动应用时触发语法错误：

[kazehoya@server145 flask-server]$ python server.py
File "server.py", line 47
doc_ref = db.collection("admins").document(f"{admin.uid}")
SyntaxError: invalid syntax
[kazehoya@server145 flask-server]$

注：该应用在本地环境运行完全正常。

4. 手动安装单个依赖的错误 #

尝试执行python -m pip install firebase时出现回溯错误：

Traceback (most recent call last):
File "/usr/lib64/python2.6/runpy.py", line 122, in _run_module_as_main
"__main__", fname, loader, pkg_name)
File "/usr/lib64/python2.6/runpy.py", line 34, in _run_code
exec code in run_globals
File "/home/kazehoya/newcorny.kazemo.shop/newcorny.kazemo.shop/flask-server/pip.py", line 29, in 
"This script does not work on Python {}.{}".format(*this_python),
ValueError: zero length field name in format

9月5日更新 #

已解决pip运行问题，但仍存在wheel构建失败错误。附上Python应用页面截图：

恳请提供帮助！😊
