将刮擦添加到平面项目中时出错

Question

我在建一个平面建筑的侏儒建筑项目。现在我想在我的项目中添加刮痕。我使用平板式脉冲发生器生成刮擦包并将其添加到清单中如下：

"modules": [
  "python3-cryptography",
  "python3-scrapy.json",
  {
    "name": "other-modules"
  }
]

但是，当我运行时，我会得到以下错误：

            Upgrade to the latest pip and try again. This will fix errors for most
            users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip

如果我加上“python3-setuptools_锈病”，就会导致这个错误：

ERROR:Could not build wheels for cryptography which use PEP 517 and cannot be installed directly

有什么办法解决这个问题吗？Tks预先

您是否尝试过将您的pip升级到最新版本，我在您的日志中看到了，也许可以尝试一下。
