Question

我的堆栈： python 3.6 Node.js 11.3.0 jsii-0.20.11（通过npm安装aws cdk时自动安装）

我刚刚尝试了ckd init，然后进行了pip install -e。之后，我进行了cdk部署，它给了我以下错误。

Traceback (most recent call last):
  File "app.py", line 3, in <module>
    from aws_cdk import core

Answer 1

通常表示某种版本的missmarch：npm中的aws-cdk和python中的aws-cdk。鉴于这是一个很老的问题，我想更新所有软件包甚至重新安装环境都应该有所帮助。

在aws-cdk官方错误跟踪器中提到了类似的问题：

我同意，这令人沮丧并且很难找到解决方法。使用@Trilliput中的链接

我的步骤：

卸载点子
更新自制软件
删除aws cli
重新安装aws cli
卸载AWS cdk
重新安装AWS cdk

命令：

sudo pip uninstall pip
brew update
sudo rm /usr/local/bin/aws
sudo rm /usr/local/bin/aws_completer
sudo rm -rf /usr/local/aws-cli
curl "https://awscli.amazonaws.com/AWSCLIV2.pkg" -o "AWSCLIV2.pkg"
sudo installer -pkg AWSCLIV2.pkg -target /
pip3 uninstall aws-cdk.cdk
pip3 install aws-cdk.cdk --use-feature=2020-resolver

那没有我希望的那样，所以我在下面使用了所有这些命令。我称它为焦土重装：

sudo pip uninstall pip
brew update
sudo rm /usr/local/bin/aws
sudo rm /usr/local/bin/aws_completer
sudo rm -rf /usr/local/aws-cli
brew uninstall node
brew uninstall pyenv

# CLOSE your terminal window and open a NEW terminal window.  
# when you run [which python] you should get /usr/bin/python
# run these commands to remove node and npm

curl "https://awscli.amazonaws.com/AWSCLIV2.pkg" -o "AWSCLIV2.pkg"
sudo installer -pkg AWSCLIV2.pkg -target /

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
python3 get-pip.py

brew install python3

# old CDK
pip3 uninstall aws-cdk.cdk

#new CDK
pip3 uninstall aws-cdk.core

# NEW CDK
pip3 install aws-cdk.core

#pip3 install aws-cdk.core --use-feature=2020-resolver

# reinstall aws cdk
npm install -g aws-cdk
npm install -g npm@7.0.13
sudo npm install -g npm@7.0.13
npm install -g aws-cdk
sudo npm install -g aws-cdk
sudo -i
sudo npm install -g aws-cdk
cdk --version

AWS CDK python客户端提供了cdk部署错误
