[已解决]下载chromium源码 download_from_google_storage 无法下载文件

当使用 gclient runhooks 后

出现下面的错误

 File gs://chromium-gn/1088992877b3a13f25b61c8fc18e25296d8cab33 for src/buildtools/win/gn does not exist.

> Error: Command download_from_google_storage --no_resume --platform=linux* --no_auth --bucket chromium-gn -s src/buildtools/win/gn.sha1 returned non-zero exit status  

已经设置 .boto 以及

set NO_AUTH_BOTO_CONFIG=E:\_ChromiumDev\gclient_chromium_src\.boto

.boto 内容是：

[Boto]
proxy = 127.0.0.1
proxy_port = 

但是 貌似通过 download_from_google_storage.py 这个工具，还是无法下载谷歌的文件，上面的是使用了代理。否则某些谷歌的文件无法访问。

现在是工具无法下载，但是浏览器可以下载。

后来 查了下，以及通过浏览器下载了部分文件。没有快速的解决方案，那就自己解决吧。

于是乎 写个 wget 下载的bat脚本，把缺失的文件批量下载下来！

运行 gclient runhooks 出现的所有

 0> File gs://chromium-gn/1088992877b3a13f25b61c8fc18e25296d8cab33 for src/buildtools/linux32/gn does not exist, skipping.

这样的错误，只要用上面的bat脚本运行下就可以下载了。直到 gclient runhooks 没有报错。就可以进行下一步 编译 chromium了。

编译chromium就是命令：

ninja -C src/out/Debug chrome

又出现了错误

ninja: build stopped: subcommand failed.

通过下面命令查看 具体哪里出错了。因为 批量任务，一下子刷屏了，看不到错误在哪里。

ninja -C src/out/Debug chrome|findstr error

rated_cjk_delta_bi_4.cc : error C2220: 警告被视为错误 - 没有生成“object”文件
注意: 包含文件:      C:\Program Files (x86)\Windows Kits\8.0\Include\shared\winerror.h
注意: 包含文件:      C:\Program Files (x86)\Windows Kits\8.0\Include\shared\winerror.h

解决方案，修改文件编码。

  今天编译gamebryo，出现error C2220: 警告被视为错误 - 没有生成“object”文件，晕死，在公司编译的时候还好好的。打开文件看了下，就是个头文件，里面定义了几个宏error <wbr>C2220: <wbr>警告被视为错误 <wbr>- <wbr>没有生成“object”文件。没办法，清除，重新编译，错误依旧，又搞了半天终于找到错误原因error <wbr>C2220: <wbr>警告被视为错误 <wbr>- <wbr>没有生成“object”文件

这种错误的原因是：原因是该文件的代码页为英文，而我用的系统中的代码页为中文。

解决方案：

1. 文件->打开->选择，然后保存。从新打开程序文件运行，此错误不再出现。

我用 notepad++ 配合everything 快速打开目标文件，然后 格式 转为 ansi编码。原来的是 utf8 no-bom 编码。这种编码，cl.exe MSVC的编译器 老是报错。
