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If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it.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.
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.

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。
