error: can't find Rust compilerIf you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it.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 pipand 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.[end of output]note: This error originates from a subprocess, and is likely not a problem with pip.ERROR: Failed building wheel for tokenizers

方法：

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
info: downloading installer或者
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

然后重新打开终端

最后重新安装transformer

pip install transformers==4.15.0

我是第一种有效。
