rust - rust 同步 channel 更新错误 'nightly --- (error reading rustc version)'

Question

我遇到了自动完成错误，所以我决定重新安装所有东西，但是在执行时出现了这个错误:

rustup update nightly

info: syncing channel updates for 'nightly-x86_64-unknown-linux-gnu'

nightly-x86_64-unknown-linux-gnu unchanged - (error reading rustc version)

在 rust rustc 1.17.0 中

Answer 1

做的时候:

->rustup override set nightly-x86_64-unknown-linux-gnu
info: using existing install for 'nightly-x86_64-unknown-linux-gnu'
info: override toolchain for '/home/' set to 'nightly-x86_64-unknown-linux-gnu'

  nightly-x86_64-unknown-linux-gnu unchanged - rustc 1.19.0-nightly (d3abc80b3 2017-05-09)

现在能够识别:

• nightly-x86_64-unknown-linux-gnu 不变 - rustc 1.19.0-nightly (d3abc80b3 2017-05-09)

代替

• nightly-x86_64-unknown-linux-gnu unchanged -(读取 rustc 版本时出错)

然后我每晚更新，因为它可能已损坏，也可能没有，这是正常的，也许它会起作用

->rustup update nightly
info: syncing channel updates for 'nightly-x86_64-unknown-linux-gnu'

  nightly-x86_64-unknown-linux-gnu unchanged - rustc 1.19.0-nightly (d3abc80b3 2017-05-09)

我做了一些测试，一开始没认出来 rustc 1.19.0-nightly (d3abc80b3 2017-05-09) 我不得不执行 2 次 ->rustup update nightly

---

根据正在寻找可以使用toolchain uninstall 但最后这个我无法确认:

->rustup toolchain uninstall nightly
info: uninstalling toolchain 'nightly-x86_64-unknown-linux-gnu'
info: toolchain 'nightly-x86_64-unknown-linux-gnu' uninstalled

->rustup self update

//..
->rustup update nightly
//..

注意:也许这个 (error reading rustc version) 真的不是任何严重的“错误”并且可以在不识别版本的情况下工作 rustc 1.19.0-nightly (d3abc80b3 2017-05- 09)
