安装后，布朗尼找不到@openzeppelin

Question

布朗尼没有发现openzeppelin合同，即使Brownie知道它已经安装了。

(base) andrea@andrea-ThinkPad-S430:~/MEGA/smart_contracts/demos/ERC20-brownie$ brownie pm install OpenZeppelin/openzeppelin-contracts@4.5.0
Brownie v1.18.1 - Python development framework for Ethereum

  File "brownie/_cli/__main__.py", line 64, in main
    importlib.import_module(f"brownie._cli.{cmd}").main()
  File "brownie/_cli/pm.py", line 39, in main
    fn(*args[""])
  File "brownie/_cli/pm.py", line 93, in _install
    package_id = project.main.install_package(uri)
  File "brownie/project/main.py", line 796, in install_package
    return _install_from_github(package_id)
  File "brownie/project/main.py", line 850, in _install_from_github
    raise FileExistsError("Package is aleady installed")
FileExistsError: Package is aleady installed

知道为什么吗？我对@chainlink也有类似的问题。

非常感谢

我认为关键字brownie所期望的是“重新映射”，而不是重新映射。这能解决问题吗？
