ModuleNotFoundError: No module named 'cryptography'
在您的问题中,引用和引用指出了在安装了Crypto模块后仍然出现ModuleNotFoundError的问题。引用提供了一些试错经验来解决这个问题。根据引用的经验,您可以尝试以下步骤来解决ModuleNotFoundError: No module named 'cryptography'的错误:
1. 首先,确保已经卸载了之前安装的Crypto模块。您可以使用以下命令卸载:
```
pip uninstall crypto
```
2. 然后,安装pycryptodome模块。您可以使用以下命令来安装:
```
pip install pycryptodome
```
3. 在安装完成后,重新运行您的Python脚本。现在,应该可以正常导入cryptography模块,而不再出现ModuleNotFoundError的错误。
需要注意的是,引用中提到,即使安装了pycryptodome模块并且成功导入了cryptography模块,但某些IDE(例如PyCharm)可能仍然无法识别模块名称。这可能导致在IDE中出现错误提示,但实际上您的脚本可以在命令行中正常运行。如果您遇到这种情况,您可以尝试使用命令行来运行您的脚本,或者尝试使用其他IDE来避免这个问题。
希望这些步骤可以帮助您解决ModuleNotFoundError: No module named 'cryptography'的问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
