我有一个virtualenv的问题，我不知道我是如何造成它的。我遇到的问题是我无法在我的烧瓶应用程序的site-packages目录中安装任何flask-extensions。
我有一个之前覆盖过的stackoverflow问题，但我相信我发现了root问题，问题出在virtualenv本身。执行=IIF(SUM(IIF(Isnothing(Fields!Total.Value),0,Fields!Total.Value)) = 0,
"",
SUM(IIF(Isnothing(Fields!Total.Value),0,Fields!Total.Value)).ToString + " J"
)
时出现错误：
virtualenv env New python executable in env/bin/python

中有某种权限被拒绝，我不确定这意味着什么。有没有办法完全删除virtualenv。新应用程序的/lib目录不包含激活文件或任何内容。
此外，运行这些命令会产生以下结果：
bin但是当我执行(sudo) pip uninstall virtualenv
zsh: /bin/pip: bad interpreter: /usr/local/opt/python/bin/python2.7: no such file or directory
sudo: unable to execute /bin/pip: No such file or directory
和which virtualenv时，我明确地将它们放在which pip和/usr/local/bin/virtualenv/下。
有什么想法吗？
答案 0 :(得分：1)
我发现了问题！问题出在此文件/Users/drubio/.pydistutils.cfg
对于我遇到的另一个问题（我记不住了）我需要将这两行用于解决方法：
[install]
prefix=''
删除这些行使它工作。
