How to work around rustup-init failure
(Jin Qing's Column, Mar., 2022)
rustup-init.exe may fail if some anti-virus software is running with realtime protection.
The error message is like this after many retries:
error: could not rename component file from 'C:\.../rust/html' to 'C:\.../rust/html'
And it is not possible to stop the anti-virus for a corporate laptop.
There is a way to workaround this. Here are the steps:
rustup-init until it begins to retry renaming
- Kill rustup-init when it is retrying
rustup will be installed before the failure
- do not let rustup-init do the cleanup after the final failure
rustup update to install all.
rustup-init again to setup others.
rustup update will report that rustc was not found:
