EOS nodeos 启动时 boost::filesystem::current_path: No such file or directory 错误

昨天更新 EOSIO 到 1.5.0 ，然后今早启动的时候就报错了，启动命令如下

nodeos -e -p eosio --plugin eosio::producer_plugin --plugin eosio::history_plugin --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin --plugin eosio::http_plugin -d /Users/yufei/Developer/eos/data --config-dir /Users/yufei/Developer/eos/data/config --http-server-address=0.0.0.0:8888 —-access-control-allow-origin='*' --contracts-console --http-validate-host=false --filter-on='*'

错误显示如下

发生这个错误的原因是因为老版本的还存在，而且部分命令和插件使用的是老版本。

因此，修复方法也很简单，只要执行以下命令即可

sudo ./scripts/clean_old_install.sh

然后就可以愉快的启动了～～～

然后我们再看看这个 clean_old_install.sh 脚本文件，内容如下

if [ -d "/usr/local/include/eosio" ]; then
   printf "\n\tOld eosio install needs to be removed.\n\n"
   printf "\tDo you wish to remove this install? (requires sudo)\n"
   select yn in "Yes" "No"; do
      case $yn in
         [Yy]* )
            if [ "$(id -u)" -ne 0 ]; then
               printf "\n\tThis requires sudo, please run ./scripts/clean_old_install.sh with sudo\n\n"
               exit -1

哈，其实就是删除 /usr/local/include/eosio 下的老文件
