我有一个使用pyvisa的脚本。在python控制台上一切正常但冻结我得到一个TypeError。
debug.py：
import visa
def main():
visa.log_to_screen()
rm = visa.ResourceManager()
# works
instr = rm.open_resource("GPIB0::12::INSTR")
# fails in frozen executable
instr = rm.open_resource("GPIB0::12::INSTR", write_termination="\r\n")
if __name__=="__main__":
main()
setup.py：
from cx_Freeze import setup, Executable
import os, site
[python_dir, site_dir] = site.getsitepackages()
include_files = []
missing_dll = ["msvcr100.dll"]
for dll in missing_dll:
include_files.append((os.path.join(python_dir, dll), dll))
buildOptions_exe = dict(
compressed = False,
# includes = ["pyvisa"], # doesn't solve this issue
include_files = include_files
)
setup(
name = "Debugger",
author = "Name",
version = "0.0.0",
options = dict(build_exe = buildOptions_exe),
executables = [Executable("debug.py"),]
冻结脚本的执行：

这种重新定义在哪里来自？
