我正在尝试创建一个 virtualenv，但我收到了 Permission denied 错误。我正在使用以下代码

python2.7 -m virtualenv -p `which python2.7` test

这给出了这个错误信息：

为了调试os.py 中的错误，我添加了一个打印语句，看起来脚本试图创建目录/lib/python2.7 and /lib/python2.7/site-packages。我不明白为什么 virtualenv 试图在那里而不是在我当前的目录中创建这些目录。

我已经安装了没有 sudo 的 virtualenv，所以我不希望它在 root 拥有的路径中创建目录。

最后只有python可执行文件被复制到'test'目录，而不是setuptools、pip和wheels。

有没有办法避免 virtualenv 访问根目录？

将 python3 与 venv 一起使用可以正常工作，问题出在 virtualenv 上。

从我的主目录执行 virtualenv 没有错误。

Answer 1

看起来您正在尝试在 /lib/python2.7/site-packages 内创建 virtualenv test，但无论如何，您不应该拥有写入权限。

先尝试运行cd ~，在你的主目录中创建venv。

我也遇到了同样的神秘错误；原来我忘记了 $HOME/.pip/pip.conf 中更改前缀的设置。
