基本上,我试图从savReaderWriter模块运行一些Python代码,以创建一个准备在IBM SPSS中打开的.sav文件.作为macOS用户,我需要首先在终端中运行以下两行以使模块正常工作：
echo 'export DYLD_LIBRARY_PATH=/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/savReaderWriter/spssio/macos' >> ~/.bash_profile
echo 'export LC_ALL=en_US.UTF-8' >> ~/.bash_profile
在下面,您可以看到我试图在Python中运行的一段代码：
import savReaderWriter
savFileName = "someFile.sav"
records = [['Test1', 1, 1], ['Test2', 2, 1]]
varNames = ['var1', 'v2', 'v3']
varTypes = {'var1': 5, 'v2': 0, 'v3': 0}
with savReaderWriter.SavWriter(savFileName, varNames, varTypes, ioUtf8=True) as writer:
for record in records:
writer.writerow(record)
我的问题是,通过terminal.app在Python中运行代码时,就像一个超级按钮,并且出现了一个新的.sav文件,尝试在IDE中执行相同的代码(尝试过PyCharm和Spyder)会给我一个错误：

模块作者无法在此问题上为我提供帮助,因此,对于这个社区的任何建议,我将感到非常高兴.
编辑(添加sys.path)：
从终端：
['',
'/Library/Frameworks/Python.framework/Versions/3.6/lib/python36.zip',
'/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6',
'/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/lib-dynload',
'/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages',

从IDE：

问候,

解决方法:
找到了解决方案！
基本上,我需要创建指向错误中出现的每个dylib的符号链接,示例如下：
sudo ln -s /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/savReaderWriter/spssio/macos/libicudata48.1.dylib /usr/local/lib/libicudata48.1.dylib
sudo ln -s /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/savReaderWriter/spssio/macos/libicui18n48.1.dylib /usr/local/lib/libicui18n48.1.dylib
sudo ln -s /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/savReaderWriter/spssio/macos/libspssdio.dylib /usr/local/lib/libspssdio.dylib
sudo ln -s /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/savReaderWriter/spssio/macos/libzlib123spss.dylib /usr/local/lib/libzlib123spss.dylib
因此从理论上讲：
sudo ln -s /path/to/original /path/to/symbolic/link
问候,
MG
