Question

我在Lion的virtualenv遇到了麻烦。我已经清理了重新安装的Virtualenv和Pip它，但似乎在创建一个新环境时正在努力寻找Pip。我删除了virtualenvwrapper以确保它不会干扰。

不幸的是，它正在查看的路径似乎在错误消息中被截断。

环境已创建部分，但没有激活脚本。这是追溯：

蒂姆：你可能从我在这个链接上看到的内容正确 - https://bitbucket.org/tarek/distribute/issue/168/easy_install-fails-with-byte-compiling

在链接的末尾还有另一个有趣的注释，您可能想要查看。它说 “设置导出VIRTUALENV_USE_DISTRIBUTE = 1解决了问题。”

我建议您使用分发来安装软件包，因为它似乎比传统的setuptools少了很多麻烦。使用 - 分发选项，如下所示： -

# Not using distribute, uses setuptools
$ virtualenv test1
New python executable in test1/bin/python
Installing setuptools............done.
Installing pip...............done.

# Using distribute by specifying the option
$ virtualenv --distribute test2 
New python executable in test2/bin/python
Installing distribute.....................................................................................................................................................................................done.
Installing pip...............done.

无论如何，很高兴你解决了自己的问题！： - ）

Answer 2

当您在Python中禁用字节编译（.pyc文件）时，easy_install无法正常工作。我在我的开发机器上做了这个，因为当我删除原始.py时，由于.pyc文件被使用，我一直在努力克服错误。

为了纠正这个问题，我删除了

export PYTHONDONTWRITEBYTECODE=1

来自~/.profile。

calvinx的回答也通过使用distribute而不是easy_install来解决这个问题。我认为这两个答案都可以被认为是正确的，但是calvinx允许你继续禁用字节编译，所以我会将其标记为正确。

Answer 3

我解决了它只是删除了所有的.pyc文件

无法在Lion中创建新的Virtualenv
