Question

尝试更新virtualenv中的python安装或创建新的virtualenv时会发生这种情况：

[marcintustin@localhost oneclickrep]$ virtualenv --always-copy --clear --python=/usr/bin/python oneclickcosvirt/ 
Already using interpreter /usr/bin/python
Deleting tree oneclickcosvirt/lib/python2.7
Not deleting oneclickcosvirt/bin
New python executable in oneclickcosvirt/bin/python
Traceback (most recent call last):
  File "/usr/bin/virtualenv", line 9, in <module>
    load_entry_point('virtualenv==1.10.1', 'console_scripts', 'virtualenv')()
  File "/usr/lib/python2.7/site-packages/virtualenv.py", line 821, in main
    symlink=options.symlink)
  File "/usr/lib/python2.7/site-packages/virtualenv.py", line 956, in create_environment
    site_packages=site_packages, clear=clear, symlink=symlink))
  File "/usr/lib/python2.7/site-packages/virtualenv.py", line 1377, in install_python
    shutil.copyfile(py_executable_base, full_pth)
  File "/usr/lib/python2.7/shutil.py", line 82, in copyfile
    with open(src, 'rb') as fsrc:
IOError: [Errno 2] No such file or directory: 'python'
[marcintustin@localhost oneclickrep]$

结果始终如一。 /usr/bin/python存在并且工作得非常好（它也是由which拾取的python）。这是什么原因？

编辑：使用virtualenv版本1.10.1

Answer 1

这是virtualenv的错误。使用--always-copy标志会触发复制行为，该行为已被破坏。已经提交了错误报告和补丁。

第shutil.copyfile(py_executable_base, full_pth)行应为shutil.copyfile(py_executable, full_pth)。

Virtualenv：无法创建virtualenv：IOError：[Errno 2]没有这样的文件或目录：'python'
