英文:
golangci-lint gives unseen errors after reinstalling
问题
我将go的版本升级到了go1.18.3，按照https://go.dev/doc/install上的指示进行操作：
rm -rf /usr/local/go && tar -C /usr/local -xzf go1.18.3.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin
然后我尝试运行我的go项目的Makefile，但提示未安装golangci-lint。我猜这可能是由于rm -rf /usr/local/go导致所有的包都被删除了，或者在升级过程中我弄乱了文件。
我继续安装golangci-lint：
go install github.com/golangci/golangci-lint/cmd/golangci-lint@v1.46.2
报告了许多以前未见过的错误，比如：
could not import math/bits (-: could not load export data: cannot import "math/bits" (unknown export format version 2), export data is newer version - update tool)
undeclared name: `yaml
...
我感到很困惑，因为在进行代码检查之前，该项目曾经成功编译过。我应该降级golangci-lint吗？
英文:
I upgraded the version of go to go1.18.3, following the instruction on https://go.dev/doc/install:
rm -rf /usr/local/go && tar -C /usr/local -xzf go1.18.3.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin
Then I tried to run a Makefile for my go project but was prompted that golangci-lint was not installed. I assume that this was due to rm -rf /usr/local/go and all the packages were removed, or I somehow messed up with the files during the upgrade.
I went on to install golangci-lint:
go install github.com/golangci/golangci-lint/cmd/golangci-lint@v1.46.2
A lot of previously unseen errors were reported. Like
could not import math/bits (-: could not load export data: cannot import "math/bits" (unknown iexport format version 2), export data is newer version - update tool)'
undeclared name: `yaml
...
I'm quite confused because the project used to compile successfully after lint checks.
Should I downgrade gplangci-lint?

go install 将会把 golangci-lint 安装到你的 go/bin 路径中。之前它就是存在那里的，你说得对，rm -rf /usr/local/go 命令会将其删除。
至于新报告的错误，每次 golangci-lint 的更新都会引入更多的规则和检查器。你可以选择降级、修复这些错误，或者根据你的偏好配置 golangci-lint。详情请参考：https://golangci-lint.run/usage/configuration/
英文:
go install Will install golangci-lint into your go/bin path. And that is previous where it lived and you are correct that rm -rf /usr/local/go would have remove it.
As for the newly reported errors, every update of golangci-lint will bring in more rules and linters. You can either downgrade, fix the errors or configure golangci-lint to your preferences https://golangci-lint.run/usage/configuration/
