Python打包问题（Ppt）：尝试运行使用命令行中的non.py文件的打包项目时出错

Question

在执行$ pip install path/to/MyProject-0.1.0.tar.gz我能够使用python解释器成功地从我计算机上的每个目录import myproject 。

但是，我的目标是能够从每个目录运行$ myproject 。 当我运行$ myproject我得到了这个：

IOError: [Errno 2] No such file or directory: '/home/username/.virtualenvs/vir_env/local/lib/python2.7/site-packages/myproject/myproject_style.cssc'

我查看了/home/username/.virtualenvs/vir_env/local/lib/python2.7/site-packages/myproject/ dir， myproject_style.css文件就在那里。

注意错误说cssc而不是css 。 我不知道为什么我会收到此错误，因为当我导航到myproject目录并执行$ python __init__.py时程序运行完全正常

问题不是那么明显，但我想我知道什么是错的。

这行代码：

path_to_myproject = os.path.abspath(__file__)

不仅可以返回“... / __ init__.py”，还可以返回“... / __ init __。pyc”字符串

因此这行代码：

path_to_myproject_css = path_to_myproject.replace("/__init__.py", "/myproject_style.css")

不仅会__init__.py，还会__init__。 pyc - py模块的字节编译版本。 这是你获得cssc而不是css的最可能原因; 你只需在字符串“... / __ init __。pyc”中用“/myproject_style.css”替换“/__init__.py”。
