+
+### 解决办法
+
+
+#### 办法1
+
+> 相关Issue:https://github.com/shirou/gopsutil/issues/149
+> If you copy process_darwin_amd64.go to process_darwin_386.go, you can build. But it might be not work because struct size is different.
+> Since I can not get i386/darwin machine, I can not get struct size on 386 environment. FreeBSD/Linux on i386 can be get from AWS, but no darwin.
+> I can just add process_darwin_386.go to the repository, with warning comment. Do you really needs to darwin/386?
+
+
+
+简言之：修改gopsutil包中 `process_darwin_amd64.go`文件名为`process_darwin.go`
+
+#### 办法2
+
+如果make时出现关于这个包的错误https://github.com/shirou/gopsutil，在go.mod 和go.sum 下删除gopsutil包后重新go mod tidy 后就可以解决了
+
+```shell
+-       github.com/shirou/gopsutil v2.16.13-0.20170208025555-b62e301a8b99+incompatible
++       github.com/shirou/gopsutil v3.21.11+incompatible
+```
+
+
+### 其他类似的问题
+
+
+报错...
+
+```shell
+go test -coverprofile=.coverage.out `go list ./...` -short
+# github.com/shirou/gopsutil/cpu
+../../go/pkg/mod/github.com/shirou/gopsutil@v2.20.9+incompatible/cpu/cpu_darwin_cgo.go:13:5: error: 'TARGET_OS_MAC' is not defined, evaluates to 0 [-Werror,-Wundef-prefix=TARGET_OS_]
+   13 | #if TARGET_OS_MAC
+      |     ^
+1 error generated.
+
+```
+
+详细的报错具体大概是这种，如果想了解错误的原因可以查看官方Issue或者文档github.com/shirou/gopsutil包版本太低导致的TARGET_OS_MAC错误
