ImportError with Pyinstaller and Pandas
提问by gwaldman13
I am trying to bundle a short python script into a single executable. I am able to successfully run pyinstaller using
我正在尝试将一个简短的 python 脚本捆绑到一个可执行文件中。我能够成功运行 pyinstaller 使用
pyinstaller script.py
However, when I run the executable I get the following error. I have tried everything and nothing seems to work.
但是，当我运行可执行文件时，出现以下错误。我已经尝试了一切，但似乎没有任何效果。
C:\Users\...\Python\dist\script>script

ImportError: C extension: lib not built. If you want to import pandas from the s

Here are the imports in my script:
这是我的脚本中的导入：
import pandas

from pandas import Series, DataFrame
import vertica_python
from StringIO import StringIO

Edit your .specfile to add the lines shown below just after the a = Analysis part. Then build using the --onefile flag– e.g., pyinstaller --onefile my_project.spec
编辑您的.spec文件以在a = Analysis part. 然后使用--onefile flag- 例如，pyinstaller --onefile my_project.spec
a = Analysis(...)
# Add the following
def get_pandas_path():
import pandas
pandas_path = pandas.__path__[0]
return pandas_path
dict_tree = Tree(get_pandas_path(), prefix='pandas', excludes=["*.pyc"])
a.datas += dict_tree
a.binaries = filter(lambda x: 'pandas' not in x[0], a.binaries)
The reason this is necessary is PyInstaller is grabbing pandas python code, but not grabbing the lib. This means that when the pandas code runs (from 'inside' the executable) it can't find the lib – so it tries to be helpful and suggest you need to build it.
这是必要的原因是 PyInstaller 正在抓取 Pandas python 代码，而不是抓取 lib。这意味着当 Pandas 代码运行时（从可执行文件的“内部”）它找不到 lib——所以它试图提供帮助并建议你需要构建它。
The workaround is detailed at http://github.com/pyinstaller/pyinstaller/issues/1580– it appears it might not work for all versions / operating systems, so best of luck.
解决方法在http://github.com/pyinstaller/pyinstaller/issues/1580 中有详细说明——它似乎不适用于所有版本/操作系统，所以祝你好运。

The error
错误
ImportError: C extension: lib not built.
Clearly tells you to run python setup.py build_ext --inplace.
to build the C extensions
明确告诉你运行python setup.py build_ext --inplace。构建 C 扩展
