mysql - 在 cloud9 上安装 mongrel 报错

Question

我正在运行以下命令来安装 mongrel(将应用程序的 ruby​​ 降级到 1.8.7p302，当尝试执行 bundle create --local 时，它要求安装 mysql，然后要求安装 mongrel)

gem install win32-open3 -v '0.3.2'

(master) $ gem install mongrel -v '1.1.5'

Answer 1

进入/usr/local/lib/ruby/gems/1.9.1/gems/mongrel-1.1.5/ext/http11

并在 http11.c 上使用 sudo nano 或 vi 并且:

将第 77 行替换为

for(ch = RSTRING_PTR(f), end = ch + RSTRING_LEN(f); ch < end; ch++) {进而将第 172 行替换为冒号 = strchr(RSTRING_PTR(temp), ':');

将第 174 行替换为

rb_hash_aset(req, global_server_name, rb_str_substr(temp, 0, colon - RSTRING_PTR(temp)));

替换第 176,177 行

rb_str_substr(temp, 冒号 - RSTRING_PTR(temp)+1,RSTRING_LEN(温度)));

替换第 298 299 行

dptr = RSTRING_PTR(数据);dlen = RSTRING_LEN(数据);

保存文件，

sudo ruby​​ extconf.rb && sudo make && sudo make install

转到 cd ../../lib/mongrel(或完整路径“/usr/local/lib/ruby/gems/1.9.1/gems/mongrel-1.1.5/lib/mongrel”

sudo nano handlers.rb

修复中的case语句

在第 208-212 行，将“: false”的实例更改为“then false”

然后 sudo gem install mongrel 如果构建简单地失败了

像这样选择第二个选项

你可以像这样强制安装 mongrel

sudo gem install mongrel -v 1.2.0.pre2 -- --with-cflags=\"-O2 -pipe -march=native -w\"

这对我有用，希望对你也有用。
