AWS CDK python客户端在cdk部署中出现错误

Question

我的堆栈：

11.3.0

• jsii-0.20.11
• python 3.6
• Node.js

(通过npm安装aws cdk时自动安装)

我刚试过cdk init，然后做了pip install -e。

在此之后，我执行了cdk deploy，并给出了以下错误：

Traceback (most recent call last):
  File "app.py", line 3, in <module>
    from aws_cdk import core
  File "C:\Users\sgoud12\myfolder\myprojects\myapp\cdk\.env\lib\site-packages\aws_cdk\core\__init__.py", line 1967, in <module>

Answer 1

它通常意味着某种版本的错误: npm中的aws和python中的aws。考虑到这是一个很老的问题，我认为更新所有软件包，甚至重新安装环境都会有帮助。

在官方的aws bug跟踪器中也提到了类似的问题：

Answer 2

我同意，这是令人沮丧的，很难找到解决办法。使用@Trilliput的链接

我的脚步：

homebrew

• Remove

• 卸载pip

• 更新cli

1. 重新安装aws cli
2. 卸载aws
3. aws cdk

G 213

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

这不像我所希望的那样有效，所以我使用了下面所有的命令。我叫它焦土重新安装：

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

Answer 3

把python的版本从3.6提高到3.7.5对我来说很有魅力
