virtualenv 在错误的地方寻找 easy_install 和其他文件
virtualenv looking in the wrong place for easy_install & other files
不知何故，我在 mac 上安装了 python 2.7，因此我尝试使用 "brew install python" 重新安装。现在，当我尝试创建一个新的 virtualenv 时，它会抛出一个关于找不到 /bin/easy_install 的错误。 easy_install实际上是在/usr/local/bin/easy_install。如果我将它符号链接到 /bin，virtualenv 会失败并显示 /bin/pip 等等 - 它正在寻找的每个文件实际上都在 /usr/local/bin 而不是 /bin
如何才能使 virtualenv 永久显示在正确的位置：/usr/local/bin？

但它应该在 /usr/local/bin 中查找，因为这是我现在唯一的 easy_install 并且它有效：
$ which easy_install

$ easy_install

我试过 pip uninstall virtualenv 然后 pip install virtualenv 但这没有帮助 - 同样的问题。
有人知道如何解决这个问题吗？
谢谢！

编辑：已解决！
尝试使用 /usr/local/bin/virtualenv-2.7 并按预期工作。我移动了 /usr/local/bin/virtualenv，然后将 /usr/local/bin/virtualenv-2.7 符号链接回 /usr/local/bin/virtualenv --- 现在一切似乎都很好。

我自己编译的 Python 3、然后安装virtualenvwrapper。但是在我从编译自己的 Python 切换到使用 deadsnakes PPA 之后，我 运行 遇到了上述问题中描述的问题。
virtualenv 脚本的 #! 部分似乎有问题。
我收到的错误如下：

我想知道这个神秘的、完全不存在的 /usr/local/bin/python3.6 在代码中的什么地方。
所以我安装了一个full-text搜索工具并在~/.local文件夹中寻找它。
nb@ubuntu-0xA520322HC30H:~$ cd .local

两个地方似乎是对 Python 的静态引用。
我现在有两个选择：
我可以编辑 /usr/local/bin/python3.6 中的文本以引用 /usr/bin/python3.6
我可以从 /usr/local/bin/python3.6 -> /usr/bin/python3.6
我选择 bin/virtualenv-clone 文件的选项 1：
但我也做了选项 2，以防万一这个问题存在于我系统的其他地方。
nb@ubuntu-0xA520322HC30H:~$ sudo ln -s /usr/bin/python3.6 /usr/local/bin/python3.6

总结：找出你的 virtualenv 试图使用哪个解释器位置，并从那个位置建立一个符号链接到你的实际 Python.
你需要这样做的原因是至少有几个 virtualenv 位置会有一个 #! 行指向一个特定的位置，但是如果你，比如说，从编译你的拥有 Python 使用 PPA。
起初我很犹豫要不要这样做，因为我更喜欢让包管理器处理这类事情，而不是让我的路径过于复杂。但似乎真的没有任何其他方法可以解决这个问题。我尝试卸载并重新安装 virtualenv 和 virtualenvwrapper，但无济于事。
¹嗯……我的 .local/bin 里有 pbr。接下来是什么，我的.local/fridge？该死的潮人
