Python3没有这样的文件或目录 [英] Python3 no such file or directory

问题描述

我正在尝试制作python3可执行脚本并从shell运行它们.我在系统上安装了python 3.4.0.因此，我将'/home/spandan/python_codes'目录添加到 PYTHONPATH ，因为我打算将脚本和模块保存在这里.

I am trying to make python3 executable scripts and run them from shell.I have python 3.4.0 installed on my system. So, I added '/home/spandan/python_codes' directory to PYTHONPATH, as I am planning to keep my scripts and modules here.

但是，在尝试执行这些命令时，系统会抛出上述错误，除非我进入python_codes目录然后执行它们，否则脚本将不会执行.

However, while trying to execute these, the above error is thrown by the system, and the scripts wont execute unless I go into the python_codes directory and then execute them.

执行python程序:在这里我发现PYTHONPATH与编写脚本无关，以及如何设置python shebang.所以我将我的设置为#！/usr/bin/env python3.4.0

Executing python program : Here I found out that PYTHONPATH is irrelevant while making scripts, and also how to set the python shebang. So I set mine as #!/usr/bin/env python3.4.0

对吗?

推荐答案

您不必将python代码放在​​全局路径中.只需使您的python 3.4解释器解释器全局可用即可.为此，请在主目录中编辑.bash_profile或.bashrc文件，然后添加以下行:

You don't have to put your python codes in a global path. Just make your python 3.4 interpreter interpreter available globally. For that, edit .bash_profile or .bashrc file in your home directory and add the following line:

export PATH=${PATH}:/usr/bin/python3

这将使python3可执行文件，而不管您当前的工作目录如何.为了从您的codes目录执行代码，您只需要编写:

That will make python3 executable irrespective of your current working directory. In order to execute code from your codes directory, you just have to write:

$ python3 ./your_code.py

另一种方法是在代码的顶部添加shebang作为

Another way is to add the shebang at the top of your code as

#/usr/bin/python3

并修改权限为当前用户可执行(默认没有执行权限).

and change the permission to executable by the current user (by default it will not have execute permission).

$ chmod 744 your_code.py

然后直接执行脚本

$ your_code.py

希望我能解决您的问题.
