PyInstaller 'no module named certifi‘错误

Question

我正在尝试使用PyInstaller编译Python程序。当我尝试使用使用ssl的函数时，get an Import Error

ImportError: No module named certifi

我已经修改了.spec文件，以便包含来自Python ssl库的cacert.pem文件：

# -*- mode: python -*-
a = Analysis(['main.py'],
             pathex=['D:\\Projects\\soundcloud'],
             hiddenimports=[],
             hookspath=None)
a.datas.append(('cacert.pem', 'cacert.pem', 'DATA'))
pyz = PYZ(a.pure)
exe = EXE(pyz,
          a.scripts,
          exclude_binaries=1,
          name=os.path.join('build\\pyi.win32\\main', 'main.exe'),
          debug=False,
          strip=None,
          upx=True,
          console=True )
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=None,
               upx=True,
               name=os.path.join('dist', 'main'))

但随后我得到了以下错误：

Traceback (most recent call last):
File "...\soundcloud\build\pyi.win32\main\out00-PYZ.pyz\api", line 186,

error:0B084002:x509 certificate routines:X509_load_cert_crl_file:system lib

在使用PyInstaller编译时，将证书包含在中以使ssl工作的正确方式是什么？

Answer 1

通过更改环境变量解决了此问题：

os.environ['REQUESTS_CA_BUNDLE'] = os.path.join(os.getcwd(), 'cacert.pem')
