如图所示,我使用了两种方法来安装scrapy模块,但都是失败了,失败的提示都相同。


第一种是:用网络安装的方法(pip install scrapy)

第二种是:lfd上下载,然后再用命令行安装但还是失败了。





各位大神有谁知道怎么安装这个模块吗?跪求

最后一行错误提示:  ERROR: Failed cleaning build dir for cryptography

      If you are seeing a compilation error please try the following steps to
      successfully install cryptography:
      1) 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
      2) Read https://cryptography.io/en/latest/installation.html for specific
         instructions for your platform.
      3) Check our frequently asked questions for more information:
         https://cryptography.io/en/latest/faq.html
      4) Ensure you have a recent Rust toolchain installed:
         https://cryptography.io/en/latest/installation.html#rust
      5) If you are experiencing issues with Rust for *this release only* you may
         set the environment variable `CRYPTOGRAPHY_DONT_BUILD_RUST=1`.

  error: can't find Rust compiler

  If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.

  To update pip, run:

      pip install --upgrade pip

  and then retry package installation.

  If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.

  This package requires Rust >=1.41.0.
