It is a bug with awscli and it might be fixed with the next versions. That's why, a best practices is to upgrade :

这是 awscli 的一个错误，可能会在下一个版本中修复。这就是为什么，最佳实践是升级：

brew upgrade awscli

回答by Nabin

You must have messed up with the brew. Try reinstalling it using: brew install awscli(followed by brew link awscliif needed).

你一定搞砸了酿造。尝试使用以下方法重新安装它：（如果需要，请brew install awscli跟随brew link awscli）。

This error occurs because your virtual environment has broken symlinks. Here is a nice solution taken from tevino's fix_virtualenvgist:

出现此错误是因为您的虚拟环境已损坏符号链接。这是取自tevino's fix_virtualenvgist 的一个很好的解决方案：

#!/usr/bin/env bash

ENV_PATH="$(dirname "$(dirname "$(which pip)")")"
SYSTEM_VIRTUALENV="$(which -a virtualenv|tail -1)"

BAD_ENV_PATHS="/usr/local"

echo "Ensure the root of the broken virtualenv:"
echo "    $ENV_PATH"

if [[ -z "$ENV_PATH" ]] || [[ "$ENV_PATH" = *"$BAD_ENV_PATHS"* ]]; then
    echo "The root path above doesn't seems to be a valid one."
    echo "Please make sure you ACTIVATED the broken virtualenv."
    echo "??  Exiting for your safety... (thanks @laymonk for reporting this)"
    exit 1
fi

read -p "??  Press Enter if you are not sure (y/N) " -n 1 -r
echo
if [[ $REPLY =~ ^[Yy]$ ]]; then
    echo "??  Removing old symbolic links......"
    find "$ENV_PATH" -type l -delete -print
    echo "  Creating new symbolic links......"
    $SYSTEM_VIRTUALENV "$ENV_PATH"
    echo "  Done!"
fi

I had similar issue while installing awscli with homebrew on mac. So final approach was "brew uninstall python3" and reinstall awscli again.

我在 mac 上使用自制软件安装 awscli 时遇到了类似的问题。所以最后的方法是“brew uninstall python3”并再次重新安装awscli。

After read the topic, It works for me:

阅读主题后，它对我有用：

1. Uninstall aws

1. 卸载 aws

1. Reinstall it again

2. 重新安装一遍

    $ brew reinstall awscli

If you have already python (python --versionworks. If not install it with brew install python). It works for me:

如果你已经有 python （python --version工作。如果没有安装它brew install python）。这个对我有用：

1. Uninstall aws

   $ sudo rm -rf /usr/local/aws
   $ sudo rm /usr/local/bin/aws
   

2. Install it again

   $ curl "https://s3.amazonaws.com/aws-cli/awscli-bundle.zip" -o "awscli-bundle.zip"
   $ unzip awscli-bundle.zip
   $ sudo ./awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws
   

1. 卸载 aws

   $ sudo rm -rf /usr/local/aws
   $ sudo rm /usr/local/bin/aws
   

2. 重新安装

   $ curl "https://s3.amazonaws.com/aws-cli/awscli-bundle.zip" -o "awscli-bundle.zip"
   $ unzip awscli-bundle.zip
   $ sudo ./awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws

I had it installed through curl, the regular way

我通过常规方式通过 curl 安装了它

$ curl "https://s3.amazonaws.com/aws-cli/awscli-bundle.zip" -o "awscli-bundle.zip"

Then it stopped working complaining about not finding python2.7

然后它停止工作抱怨找不到 python2.7

dyld: Library not loaded: @executable_path/../.Python
  Referenced from: /usr/local/aws/bin/python2.7
  Reason: image not found
Abort trap: 6

so I fixed it by following these steps (make sure you don't do this if you installed it through brew):

所以我按照以下步骤修复了它（如果你通过 安装它，请确保你不要这样做brew）：

$ sudo rm -rf /usr/local/aws
$ sudo rm /usr/local/bin/aws

Then I installed it using brew:

然后我使用 brew 安装它：

$ brew upgrade
$ brew install awscli

It's possible to trigger this error by having a problem in your virtualenv. For example, I had an existing working virtualenv and ran brew install awscliand it broke my virtualenv with this error. If that's the case, deleting and recreating your virtualenv (the same way you originally created it) should resolve the problem. It did for me.

如果您的 virtualenv 出现问题，可能会触发此错误。例如，我有一个现有的工作 virtualenv 并运行brew install awscli它并因此错误而破坏了我的 virtualenv。如果是这种情况，删除并重新创建您的 virtualenv（与您最初创建它的方式相同）应该可以解决问题。它对我有用。
