无法使用 pip Python 2.7 安装 aws-sam-cli

Question

版本

蟒蛇： 2.7.10

点18.0

aws-cli： 1.16.19

pip 18.0 from /Library/Python/2.7/site-packages/pip (python 2.7), aws-cli 版本基于 aws-cli/1.16.19 Python/2.7.10 Darwin/17.7.0 botocore/1.12.9

错误

在下面的Step 5中遇到以下错误：

Collecting aws-sam-cli
  Using cached https://files.pythonhosted.org/packages/ed/0a/448016d5004d1353229b6081c7a05d84c38be5bc70db72d0ac366372fc78/aws-sam-cli-0.6.0.tar.gz

采取的步骤

使用此参考，我执行了以下命令：

1. 安装pip

    curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py python get-pip.py

2. ADD USER_BASE_PATH到PATH ：

    export USER_BASE_PATH=$(python -m site --user-base) export PATH=$PATH:$USER_BASE_PATH/bin

3. 安装awscli

    pip --user install awscli

   必须使用user标志，因为pip install awscli失败：

    Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/urllib3-1.23.dist-info'

   考虑使用--user选项或检查权限。

4. 安装aws-sam-cli ：

    pip install --user aws-sam-cli

Answer 1

我遇到了同样的问题。 不得不升级setuptools来解决这个问题。你可以尝试运行这个命令：

pip install -U setuptools
