Pet*_*e P 8 python data-conversion pyinstaller
我有一个工作正常的程序,但当我把它变成可执行文件时PyInstaller,我有问题.我将其追溯到一个表明问题的奇怪行为.在main(),我发表以下声明:
print float('1e-07')
当我运行我的普通Python脚本时,它'1e-07'按预期打印.
当我运行我的PyInstaller .exe程序时,它会打印出来'ERR'.
有谁知道为什么会这样？
NOTE: This is not some esoteric problem I created. I have a rather large application that frequently converts strings to floats. I found that reading in previously created projects doesn't work anymore and I managed to debug this down to this one effect. I should note that sometimes it converts the numbers properly (in my program) and sometimes not. Everything else runs fine in the application - it's just this number conversion problem. People have answered with different ways of converting numbers that don't work any better. Any answer should concentrate on why something so simple in Python does not work when the application is created with pyinstaller. Currently, I cannot build a release of this software until I can fix this problem!
UPDATE: Now I have created a program consisting only of one line that prints this value and it prints as 'ERR' in the Pyinstaller generated code - must be a PyInstaller problem or a failure of mine to include a library or something. Any help would be appreciated.
The file looks like this:
def main():
print float('1e-07')
if __name__ == '__main__':
main()
Update Again:
Based on recommendations in comments, my code now looks like this:
import traceback
import sys
print "test"
try:
print float("1e-07")
except:
traceback.print_exc(file=sys.stdout)
No exception is thrown and the code just prints 'ERR' - mind you this is only in the PyInstaller generated .exe file - when run from PyScripter it executes fine.
Output from PyScripter:
test
1e-07
Output from PyInstaller generated .exe:
test
ERR
Command Line plus output:

哇！搞了一个上午，终于发现问题了。
这被追溯到一个 dll - python27.dll。
我在朋友的机器上构建了该应用程序（他的机器是 2.7.10 版本），并在我的 pyinstaller 构建之上复制了这个 dll，从而替换了我的 dll（来自 2.7.3 版本），现在一切正常了。
我曾尝试复制许多其他可疑的 .dll，但是复制这个并且只有这个 dll 解决了问题。
随后，我将整个 python 安装更新到最新的 2.7.11，并构建了测试程序，最后根据需要打印出了 1e-07。
然后，在处理了通过更新所有这些（包括 pyinstaller）而产生的所有新问题后，我能够构建我的发布应用程序。
令人震惊和惊讶的是，Python 2.7.3 显然对 PyInstaller 生成的独立可执行文件存在此问题，但情况似乎确实如此。
