我有一个运行良好的程序,但是当我通过 PyInstaller
将它变成可执行文件时,我遇到了问题。我将其追溯到证明问题的奇怪行为。在 main()
中,我放置了以下语句:
print float('1e-07')
当我运行我的普通 Python 脚本时,它会按预期打印 '1e-07'
。
当我运行我的 PyInstaller
.exe
程序时,它会打印 'ERR'
。
有人知道为什么会这样吗?
注意:这不是我创造的一些深奥的问题。我有一个相当大的应用程序,经常将字符串转换为 float 。我发现读取以前创建的项目不再有效,我设法将其调试到这种效果。我应该注意,有时它会正确转换数字(在我的程序中),有时则不会。应用程序中的其他一切都运行良好——只是这个数字转换问题。人们用不同的方式来回答转换数字的问题,但效果并不好。任何答案都应该集中在为什么在使用 pyinstaller 创建应用程序时 Python 中如此简单的东西不起作用。目前,在解决此问题之前,我无法构建此软件的版本!
更新:现在我创建了一个仅包含一行的程序,用于打印此值,并在 Pyinstaller
中打印为 'ERR'
> 生成的代码 - 必须是 PyInstaller
问题或我的失败以包含库或其他内容。任何帮助将不胜感激。
文件看起来像这样:
def main():
print float('1e-07')
if __name__ == '__main__':
main()
再次更新:
根据评论中的建议,我的代码现在如下所示:
import traceback
import sys
print "test"
try:
print float("1e-07")
except:
traceback.print_exc(file=sys.stdout)
没有异常被抛出,代码只是打印“ERR”——请注意,这仅在 PyInstaller 生成的 .exe 文件中——当从 PyScripter 运行时,它执行正常。
PyScripter 的输出:
测试
1e-07
PyInstaller 生成的 .exe 的输出:
测试
错误
命令行加输出:

最佳答案
哇!折腾了一上午,问题终于找到了。
这被追溯到一个 dll - python27.dll。
我在 friend 的机器上构建了应用程序(他的机器是 2.7.10),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),现在一切正常。
我曾尝试复制许多其他可疑的 .dll,但复制这个并且只有这个 dll 解决了问题。
我随后将我的整个 python 安装更新到 2.7.11 - 最新版本并构建了测试程序,最后它根据需要打印出 1e-07。
然后,在处理了我通过更新所有这些(包括 pyinstaller)产生的所有新问题之后,我能够构建我的发布应用程序。
令人震惊和惊讶的是,显然 Python 2.7.3 在 PyInstaller 生成的独立可执行文件中存在这个问题,但事实似乎确实如此。
