POHow to build properly an alias?
text
Body
copied!<p>I put one new alias <code>python3.3</code> in my <code>.bash_profile</code> so as to launch easily the <code>python3.3</code> version of <a href="http://www.pyzo.org/" rel="nofollow">pyzo</a>.</p> <p>I can use this alias in a terminal without any problem, but when I use something like <code>subprocess.check_call(args = ["python3.3", onePyFile])</code>, I have the following error.</p> <pre><code>Traceback (most recent call last): ... File "/Library/Frameworks/pyzo2013b/lib/python3.3/subprocess.py", line 540, in check_call retcode = call(*popenargs, **kwargs) File "/Library/Frameworks/pyzo2013b/lib/python3.3/subprocess.py", line 521, in call with Popen(*popenargs, **kwargs) as p: File "/Library/Frameworks/pyzo2013b/lib/python3.3/subprocess.py", line 818, in __init__ restore_signals, start_new_session) File "/Library/Frameworks/pyzo2013b/lib/python3.3/subprocess.py", line 1416, in _execute_child raise child_exception_type(errno_num, err_msg) FileNotFoundError: [Errno 2] No such file or directory: 'python3.3' </code></pre> <p>I guess that my alias is not seen everywhere. So how can I fix my problem ? What is the good way to build my own alias ?</p> <p>If I try <code>subprocess.check_call(args = ["python3.3", onePyFile], shell = True)</code>, I have the following error.</p> <pre><code>onePyFile.py: python3.3: command not found Traceback (most recent call last): File "mainFile.py", line 72, in <module> shell = True File "/Library/Frameworks/pyzo2013b/lib/python3.3/subprocess.py", line 545, in check_call raise CalledProcessError(retcode, cmd) subprocess.CalledProcessError: Command '['python3.3', 'onePyFile.py']' returned non-zero exit status 127 </code></pre> <p>If i just use <code>subprocess.check_call(args = ["python3.3", onePyFile])</code> where the first line of <code>onePyFile</code> is <code>#! /usr/bin/env python3.3</code>, I have the following error.</p> <pre><code>env: python3.3: No such file or directory Traceback (most recent call last): ... </code></pre> <p>I think that my problem is more about the symbolic link than the Python call. But I do not know what is wrong. Indeed this is the first time that I make a personal symbolic link with an alias.</p>
